Étude taphonomique, paléoécologique et archéozoologique des faunes de grands mammifères de la seconde moitié du Pléistocène inférieur de la grotte du Vallonnet (Roquebrune-Cap-Martin, Alpes-Maritimes, France)

Vallonnet cave (Alpes-Maritimes, France) provided archaic lithic tools together with a big amount of large mammals of the end of lower pleistocene. At the crossing of diverse ecological niches in time and space, three main levels and within them several smaller units were distinguished. The poorly mineralized bones witnessed a huge diagenetic fragmentation. The presence of the animals in the cave seems to be linked to the reasons of their death. The exhaustive and systematic observation of the bones, like the bears probably used to die inside the cave. Some other carnivores especially hyenas, used the cave as a nursery. Man also occupied the cave and had an activity mainly on large cervid bones and on some other species as well. The very progressive deposit gave a way for carnivores and porcupine to gnaw the bones on the ground before their burial. The succession of actions (man, carnivores and porcupine) on the same bones is characteristic on Vallonnet large mammals bones.     

Rôle du gypaète barbu (Gypaetus barbatus) dans la constitution de l’assemblage osseux de la grotte du Noisetier (Fréchet-Aure,Hautes-Pyrénées,France)

Located in the Aure Valley (French central Pyrénées), the Noisetier cave opens at 825 m asl. This Middle Palaeolithic site has produced a Mousterian industry associated with a rich faunal assemblage. Bone remains are dominated by Chamois then Ibex and Red deer. Taphonomic analysis strongly suggests a human origin for the Ibex and the Red deer but questions arise for the Chamois. The chamois assemblage differed from the bones of both species by its low cut marks ratio. Semi-digested bones are particularly abundant. Differences are even more perceptible for skeletal portions. For Red deer and Ibex, long bone remains are mostly shaft portions whereas for Chamois, ends are the most abundant. Comparisons of the Noisetier cave bone assemblage with different present-day reference data leads to the conclusion that Chamois bones have mostly been accumulated by bearded vultures.     

Mammalian tooth marks on the bones of dinosaurs and other Late Cretaceous vertebrates

Abstract: We describe bones from the Late Cretaceous of Alberta – including bones of large dinosaurs, a femur from the aquatic reptile Champsosaurus, and a dentary from the marsupial Eodelphis– that bear tooth marks made by animals with opposing pairs of teeth. Of the animals known from the Late Cretaceous of North America, only mammals are capable of making such tooth marks. In particular, multituberculates, which have paired upper and lower incisors, are the most likely candidates for the makers of these traces. The traces described here represent the oldest known mammalian tooth marks. Although it is possible that some of these tooth marks represent feeding traces, the tooth marks often penetrate deep into the dense cortices of the bone. This raises the possibility that, much as extant mammals gnaw bone and antler, some Cretaceous mammals may have consumed the bones of dinosaurs and other vertebrates as a source of minerals. However, none of the tooth marks described here resemble the extensive gnaw traces produced by Cenozoic multituberculates or rodents. This suggests that specialized gnawing forms may have been rare or absent in the Late Cretaceous of North America.     

Habitat et mode de vie des chasseurs paléolithiques de la Caune de l'Arago (600 000-400 000 ans)

Several human occupations have been identified within the deposits of the Caune de l’Arago Cave site, dated from 700 000 years to 100 000 years old. The exceptional wealth of these archeological levels provides an opportunity for the study of different types of habitat and behavioral patterns of Paleolithic hunters between 600 000 and 400 000 years ago. Results from preliminary studies, carried out over the last 30 years on these archeological levels, allow for the proposition of a typology for cave habitats during the Middle Pleistocene in the south of France. In fact, four types of habitat were identified and defined. They have been described according to different characteristics such as, the thickness of the archeological accumulation, the animal species represented, the season during which the animals were hunted, the state of conservation of the fossils discovered, the morpho-technological and typological characteristics of the lithics, the categories of raw materials used and the territory exploited by the hominids inhabiting the cave, as defined by the raw materials represented. The four habitation types defined are: the long duration habitat, where the cave was used as a home base; the temporary seasonal habitat, in which case the cave served as a secondary campsite; the hunting stopover and the bivouac, during which the cave was used as a refuge for short term stays. Behavioral patterns appear to be directly related to the type of habitat and oriented towards a principal activity: hunting. The activities performed by the inhabitants of the cave seem to be more diversified during prolonged or seasonal occupations, whereas they appear to be reduced or very specialised during brief stays. Generally, The characteristics studied show that the Caune de l’Arago Cave site had multiple uses over time for Anteneandertalian family groups and hunters who left traces of their activities, allowing us to better understand their lifestyle.     

Accumulations osseuses en périphérie de terriers de petits carnivores : les stigmates de prédation et de fréquentation

Faunal remains from spoil heaps of two burrows inhabited by small carnivores (fox and badger) are analysed from a taphonomical point of view. This analysis provides characteristics for bone accumulation produced by small carnivores and will be a powerful tool for deciphering site formation about the occupational alternation of small carnivores and humans. Identified species were grouped by size classes. Faunal spectrum is composed by varied species of microfauna (70%), mesofauna (30%). Macromammal remains are under represented (less than 1%) and come from scavenged carcasses. Predators and consumed species are compared on the basis of the skeletal part representation, age classes and recording of predation marks (gnawed and digested bones). Skeletal part representation shows that all taxons exhibit a low-representation of axial skeleton and autopodial bones. Predators show a high representation of hind limb bones and a low representation of the fore limb bones whereas consumed species exhibit a reverse pattern. Mortality curve analysis provides an attritional profile for carnivores and helps for the establishment of the season of occupation of the burrow. Adults largely dominate consumed species. Moreover, predation marks are found in 1% of the carnivores’ bones and from 15% to more than 40% on prey bones. The large-sized prey bones only wear gnawed marks (20%) and anthropic marks (10–20%) whereas microfaunal remains exhibits more digested marks (40%) than gnawing stigmata (5%). Medium-sized animals bones wear both marks and with the same proportions (10–15%).     

Quand désarticuler laisse des traces : le cas de l’hyperextension du coude

In this paper, we try to document butchery practices from the past. We attempt to characterize through experimental data the marks produced when dismembering using overextension of the elbow of Sheep and several bird species. For birds, the experimentation was realized with uncooked carcasses. In many cases, overextension produced break down of the olecranon fossa of the humerus, with medial wrench of the distal part. Moreover, the proximal joints of the radius and ulna are broken. Bony and uncooked forelimb Sheep bones have been dismembered by overextension. Observations were noticed only on the radio-ulnar. The ulnas had a negative wear scar up to the anconeus process. Sometimes, these marks are associated with lateral crushing of the bone. In the second part of the article, we compare our experimental data with archaeological material. Although we found many cases of dismembering by overextension on bird bones, no data were found on small ungulates material.     

Was the European cave bear an occasional scavenger?

Rabal‐Garcés, R., Cuenca‐Bescós, G., Canudo, J.I. & de Torres, T. 2011: Was the European cave bear an occasional scavenger? Lethaia, Vol. 45, pp. 96–108. The cave bear Ursus spelaeus fossils remains are quite abundant in the Late Pleistocene site of Coro Tracito (Huesca, Spain). The site constitutes the highest mountain record of cave bears in the Iberian Peninsula. Being a monospecific locality, it permits the study of the biology and dietary habits of this species. The study of the limb bones established first, the mortality pattern of this population of Ursus spelaeus and, second, the alteration pattern due to carnivore tooth‐marks. Some authors have performed similar analyses in the same kind of skeletal elements in other cave bear localities all over Europe and, therefore it has been possible to compare our results with those from other sites. The tooth‐marks found in the bones of cave bears, especially in monospecific sites, have been attributed to a scavenging behaviour. In agreement with the authors, our analysis presented here supports the hypothesis of scavenging behaviour for cave bears. □Behaviour, Late Pleistocene, Spain, taphonomy, tooth‐marks, Ursus spelaeus.     

A diagnosis of crocodile feeding traces on larger mammal bone, with fossil examples from the Plio-Pleistocene Olduvai Basin, Tanzania

Neotaphonomic studies have determined the patterns of bone damage created by larger mammalian carnivores when consuming mammalian carcasses. Typically, mammalian carnivores gnaw and break bones to various degrees in order to access marrow, grease, and brain tissue. In contrast, crocodiles attempt to swallow whole parts of mammal carcasses, inflicting in the process tooth marks and other feeding traces on some of the bones they are unable to ingest. Although crocodiles are major predators of larger mammals along the margins of protected tropical rivers and lakes, their feeding traces on bone have received little systematic attention in neotaphonomic research. We present diagnostic characteristics of Crocodylus niloticus damage to uningested mammal bones resulting from a series of controlled observations of captive crocodile feeding. The resulting bone assemblages are composed of primarily complete elements from articulating units, some of which bear an extremely high density of shallow to deep, transversely to obliquely oriented tooth scores over often large areas of the bone, along with shallow to deep pits and punctures. Some of the tooth marks (bisected pits and punctures, hook scores) have a distinctive morphology we have not observed to be produced by mammalian carnivores. The assemblages are also characterized by the retention of both low- and high-density bone portions, an absence of gross gnawing, and minimal fragmentation. Together, the damage characteristics associated with feeding by crocodiles are highly distinctive from those produced by mammalian carnivores. Modern surface bone assemblages along the Grumeti River in Tanzania's Serengeti National Park contain a mixture of specimens bearing damage characteristic of crocodiles and mammalian carnivores. Comparison of Plio-Pleistocene fossil bones from Olduvai Gorge, Tanzania, to bones damaged by captive and free-ranging Nile crocodiles reveals direct evidence of fossil crocodilian feeding from larger mammal bones associated with Oldowan stone artifacts.     

Le Paléolithique ancien de l’Europe orientale et du Caucase

Currently, only Tréhougol’naya Cave has reliably dated evidence for human settlement in Eastern Europe and Caucasus, from the beginning through the middle of the Middle Pleistocene. In Eastern Europe, assemblages from Khriatchi and Mikhailovskoé, and possibly Darvagchai I, appear to be the only stratified locations that tentatively can be compared (despite problems with these materials) with Tréhougol’naya. In the eastern limits of Central Europe, layer VI in Korolevo I is the only stratified assemblage that may be compared with Tréhougol’naya. All these Lower Paleolithic occupations yielded the Pre-Mousterian small tool industries with some pebble tools, but without Acheulean bifaces and Levallois technique. These data suggest that Eastern Europe lies outside the distribution range of the Acheulean techno-complex demarcated with the “Movius Line”. In the Southern Caucasus, the Dmanissi hominine and lithic records document the fact that the earliest small-brained humans – probably later H. habilis-rudolfensis or earlier H. ergaster-erectus hominids bearing Pre-Oldowan technology – initially left Africa and appeared in Western Asia as early as 1.8 Ma ago. However, in the Southern Caucasus, the available chronological data indicate that the Acheulean complex has a later temporal appearance here compared to the Upper Acheulean or Acheulo-Yabrudian in Western Asia. Two main Upper Acheulean industrial variants currently can be recognized in the Southern Caucasus. The first, called the Kudarian by the author (from the caves of Kudaro I, Kudaro III, and Azyk), is characterized by lithics made from mostly siliceous rocks, rare Acheulean bifaces, and non-Levallois flaking technique. The second variant is characterized by lithics made from volcanic rocks, numerous Acheulean bifaces, and often more laminar or Levallois debitage. It can be suggested that there are independent origins for these Southern Caucasus Upper Acheulean industrial variants. Possible roots of the Acheulean assemblages of Kudarian variant might be in the local earlier Lower Paleolithic small tool assemblages with some pebble tools but without Acheulean bifaces. The other Caucasus variant of the Upper Acheulean appears to be related to the Levantine Upper Acheulean.     

Beyond leopards: tooth marks and the contribution of multiple carnivore taxa to the accumulation of the Swartkrans Member 3 fossil assemblage

The ca. 1.0 myr old fauna from Swartkrans Member 3 (South Africa) preserves abundant indication of carnivore activity in the form of tooth marks (including pits) on many bone surfaces. This direct paleontological evidence is used to test a recent suggestion that leopards, regardless of prey body size, may have been almost solely responsible for the accumulation of the majority of bones in multiple deposits (including Swartkrans Member 3) from various Sterkfontein Valley cave sites. Our results falsify that hypothesis and corroborate an earlier hypothesis that, while the carcasses of smaller animals may have been deposited in Swartkrans by leopards, other kinds of carnivores (and hominids) were mostly responsible for the deposition of large animal remains. These results demonstrate the importance of choosing appropriate classes of actualistic data for constructing taphonomic inferences of assemblage formation. In addition, they stress that an all-encompassing model of assemblage formation for the hominid-bearing deposits of the Sterkfontein Valley is inadequate and that each must be evaluated individually using not just analogical reasoning but also incorporating empirical data generated in the preserved fossil samples.     

La Grotte des Félins, site paléolithique du Pléistocène supérieur à Dar Bouazza (Maroc)

In the continental sediments filling a cave that developed in Middle Pleistocene deposits near Casablanca, Morocco, a very rich mammal fauna from the last climatic cycle was discovered. It was associated with a Middle Palaeolithic poor and atypical lithic assemblage manufactured on blocks and pebbles. The lower fossiliferous layer contained abundant carbonized remains of felids. Unfortunately, the site was destroyed by quarrying before adequate excavations could be carried out.     

Les industries lithiques préoldowayennes du début du Pléistocène inférieur du site de Dmanissi en Géorgie

The lithic industry discovered at the Dmanissi site, in Georgia is dated to between 1.81 and 1.7 Myrs and is in association with a rich faunal assemblage composed of large Quaternary vertebrates, as well as several hominid fossils attributed to Homo georgicus, and attests to the human presence on the border of Europe at the beginning of the Lower Pleistocene. The material taken into account in this study was excavated from 1991 to 1999 and comprises 4446 lithic pieces coming from Beds I through VI of the site. The assemblage is very homogenous from the base to the top of the deposits and shows no significative evolutionary tendencies. The lithic material includes a high proportion of whole pebbles (33.8% of the assemblage) coming from two nearby rivers, the Mashavera and the Pinezaouri. They are essentially of fine and coarse grained volcanic tuff, basalt, but also of rhyolite, granite, quartz, as well as other volcanic and metamorphic rocks. Pebbles used for percussion, shaping or debitage were chosen according to their petrographic nature, their morphology and their size. Whole pebbles with percussion marks situated on their extremities or with isolated removals showing convexe edges, are abundant (1.3% of the assemblage). Other pebbles showing percussion marks on a flat face, were used as anvils. Broken pebbles and pebble fragments are very numerous (30.4% of the assemblage). These often show percussion marks on their cortical surfaces. Fractures are generally related to violent percussion as the pebbles were used for striking instruments, or as they were intentionally broken. Some fractures may have been caused accidentally during flaking. Pebble tools represent 4.8% of the lithic assemblage and 10% of the industry, excluding whole and fractured pebbles. These include essentially the primary choppers (pebbles with isolated concave removal negatives) (6% of the industry and 60.1% of the pebble tools), choppers showing continuous cutting edges without a point (2.1% of the industry and 21.2% of the pebble tools). Chopping-tools are very rare (0.8% of the industry and 8.7% of the pebble tools). Although choppers without pointed cutting edges were made using very few removals (3.3 on average), they usually present a regular cutting edge and seem relatively standardised. Cores are well represented (5% of the industry, excluding whole and broken pebbles). They are characterized by a low degree of exploitation and by a frequence of cortical striking platforms. Cored knapped on a single face are most frequent, representing nearly half of the pieces (42.3%), while bifacial cores are present in smaller proportions (34.2%) and multifacial cores are rare (6.3%). Non-modified flakes are very numerous and usually of small size and intentional retouch is absent. On the other hand, the cuttingedges of many the pieces; broken pebbles, pebble tools, cores and flakes, show irregular micro-retouch and irregular retouch such as isolated notches or with continuous or overlapping configuration, sometimes associated with localised crush marks which appear to have been caused by intensive use and heavy working of the pieces. A total of 31.3% of the non-modified flakes show irregular retouch on their cutting edges. One of the main characteristics of the Dmanissi industry appears therefore to be the obtaining of flakes, most often of small size, to be used without modification. The technological and typological characteristics of the lithic industry from Dmanissi allow to attribute the assemblage to a "Pre-Oldowayen" cultural horizon (Lumley de et al., 2004), characterized by the absence of small retouched tools, which appears in East Africa from 2.55 Myrs ago. This cultural horizon is present at the border of Europe, at Dmanissi, around 1.81 Myrs ago and in Western Europe, on the shores of the Mediterranean, at Barranco León about 1.3 Myrs ago and at Fuente Nueva 3 about 1.2 Myrs ago. The lithic industry from the Dmanissi site seems anterior to the Oldowan cultural horizon, characterized by the presence of standardized small retouched tools, which appears in East Africa around 1.8 Myrs ago and emerges in Mediterranean Europe around 800?000 years ago.     

Identification des impacts de projectiles sur le squelette des grands ongulés

In the context of the collective research program “functional technology of solutrean points”, conducted from 1987 to 2000, more than 300 impacts were experimentally produced on ungulate carcasses (goat, cow, horse). Based on the classification of these types of impacts proposed by P. Morel in 1991, we can estimate that only the inclusions of point fragments in the bones remain diagnostic in most archaeological contexts. The other types, such as scrapings or splittings, can be confused with tool traces, carnivore tooth marks or postdepositional alterations. P. Morel has published the results for small herbivores, and we present our results here for large herbivores. More than 200 stigmata were observed on the carcasses of an adult cow and horse following experimental shots with solutrean projectiles (shouldered points, laurel leaf points and willow leaf points) and a few reindeer antler points. These traces are concentrated around the vital parts of the animals. The most common types are marginal scrapings and splittings, but implantations are more numerous than on small ungulate skeletons. This numerically significant body of data is derived from carefully controlled experiments. Indispensable for the interpretation of the stigmata observed on bones found in Paleolithic sites, such experiments contribute to our knowledge of the conditions prey exploitation and allow us to address questions concerning the fossilization of these traces and their apparent frequency.     

L’exploitation non alimentaire des ressources animales pendant le Magdalénien au Nord-Est de la Peninsule Ibérique. L’exemple de la grotte du Parco (Alòs de Balaguer, Lleida, Espagne)

Parco cave, discovered in 1974, has yielded more than 50 objects fashioned of hard animal parts from levels dating to later phases of the Magdalenian. In the work described here, we have undertaken a technotypological analysis of this previously unstudied bone and antler assemblage. The osseous series from Parco are homogeneous and very similar to those from nearby sites of roughly the same time period; that is to say of the late Upper Magdalenian of the peninsular Mediterranean. The latter are composed primarily of hunting weapons dominated by antler projectile points, as well as eyed bone needles and a few shell ornaments. Technological analysis shows production in which there is a tight relationship between morphological type and raw material employed. The production schema saw the removal of blanks by means of groove and splinter technique, followed by shaping of pieces by scraping and finishing of them - in some cases by abrasion.     

Deux nouveaux sites à traces de pas dinosauroïdes dans la Formation Dolomitique de l’Hettangien de Lozère,Languedoc-Roussillon,France

Recent ichnological studies revealed two new localities showing dinosaur footprints in the Hettangian Dolomitic Formation from the Causses Basin, southern France. The traces are reported from the northern part of the basin, in Lozère, an area where Lower Jurassic dinosaur ichnites were poorly documented. The surfaces bearing footprints are characterized by a large number of traces. The ichnites are ascribed to Grallator (Hitchcock, 1858), Dilophosauripus (Welles, 1971) and Eubrontes (Hitchcock, 1845) whose trackmakers were theropods. Although numerous tracksites were previously described in the southern part of the Causses Basin, these three ichnotaxa are for the first time observed in association into the Dolomitic Formation.     

Les récentes découvertes à Baerya dans le district de Bijie, au nord de la province de Guizhou (Chine)

Fauna associated with stone artifacts have recently been uncovered, in the course of a survey from a cave site named Baerya, town land of Bijie, Guizhou province. The first observations suggest a human occupation. In the absence of chrono-stratigraphic data, it is not possible to assess the age of the site. Nevertheless the presence of lower Pleistocene fauna suggests a very ancient age for this human occupation. Further field research will be necessary to determinate the age and nature of the site.     

贵州毕节发现古人类化石与哺乳动物群

2008年12月在贵州毕节团结乡首次发现麻窝口洞化石点,经2009年、2012年和2013年3次发掘,在麻窝口洞上部砂质黏土地层中共发现了四千余件哺乳动物牙齿化石。2013年7月发现的3枚古人类牙齿,分别为左上犬齿、左上第一臼齿和右上第二臼齿。人类牙齿尺寸偏小,臼齿咬合面沟纹简单,没有复杂的咬合面皱纹和附尖齿带结构,牙根短而不显粗壮,上述特点有别于我国已经发现的直立人和早期智人,可归入解剖学上的现代人。与人类相伴的哺乳动物化石,经初步鉴定共计8目20科43属53种,动物群组合反映出亚热带森林生态环境。根据动物群的时代特点,地貌地层及堆积物的光释光年代测定,指示毕节麻窝口洞古人类的时代可能为中更新世晚期,或者晚更新世早期,毕节古人类牙齿的发现为东亚地区现代人的起源及演化增添了新的证据。     

Réévaluation de la présence humaine au Pléistocène inférieur dans le Sud de l'Espagne

The Early Pleistocene locality at Venta Micena (Orce, Guadix-Baza basin, province of Granada, Spain) has provided four fossil remains - skull fragment VM-0, and long bone diaphyses VM-1960, VM-3691, and VM-12000 - which have been tentatively attributed to the hominids. Although several methodologies have been used to ascertain the human affinities of these specimens - including anatomical, morphometric and immunological analyses - the results obtained have not been conclusive, instigating a persistent debate. A taphonomic approach is used here for estimating the probability that a taxon the size of Homo sp. (~ 50 kg) could be represented in the fossil assemblage by four bone fragments and no tooth remain. A least-squares regression analysis between the percentage of teeth and the body mass estimated for each taxon of large mammals (N = 20) predicts a raw abundance of six teeth for Homo sp. in the assemblage. Given that up to the present moment no tooth remains attributable to the hominids has been unearthed during systematic excavations in the Venta Micena quarry, which has provided more than 15,000 fossils of large mammals, this argues strongly against the possibility that the three bone specimens could belong to Homo sp. The phalanx CV-0 from the Early Pleistocene site of Cueva Victoria (Cartagena, Spain) has also been attributed to the genus Homo. The taxonomic assignment of this specimen is biased, however, because it was not compared with Theropithecus oswaldi, the only primate species actually recorded from this karstic locality. A comparative anatomical and morphometric analysis of fossil and modern specimens of Theropithecus suggests that CV-0 can be attributed to T. oswaldi. As a result, Cueva Victoria does not contribute additional information concerning the first human settlements in Europe. By these reasons, apart from the paleoanthropological and archaeological findings from Atapuerca (TD lower levels and Sima del Elefante), the rich archaeological assemblages from Barranco León and Fuente Nueva-3 in Orce, dated 1.3-1.2 Myrs, which include fourteen hundred stone tools of Oldowan technology, constitute at present the only unequivocal evidence of human presence in Southeast Spain during Early Pleistocene times.     

Le Moustérien de Grèce à la lumière des récentes recherches

Thanks to recent research and the re-evaluation of the archaeological material coming from older research, the Mousterian of Greece has started to become better known. Aside the surface findings, which testify the presence of Mousterian throughout the entire continental Greece, only five Middle Paleolithic sites have been excavated. Almost every remnant has been dated to the last ice age. All lithics belong to the “typical” Mousterian, while the Quina Mousterian has not been certainly testified. The Levallois method is almost always present, more or less frequent, but always dominated by non-Levallois methods. The recurrent variations, mostly centripetal, have been more frequently used. The “Micromousterian” of Asprochaliko is the only lithic assemblage from which the Levallois method is absent.     

Validation of bone surface modification models for inferring fossil hominin and carnivore feeding interactions, with reapplication to FLK 22, Olduvai Gorge, Tanzania

Resolving the issue of how Early Stone Age hominins acquired large mammal carcasses requires information on their feeding interactions with large carnivores. This ecological information and its behavioral and evolutionary implications are revealed most directly from the tooth, cut, and percussion marks on bone surfaces generated by hominin and carnivore feeding activities. This paper employs a bootstrap method, a form of random resampling with replacement, to refine published neotaphonomic models that use the assemblage-wide proportions of long bones bearing feeding traces to infer the sequences in which Plio-Pleistocene hominins and carnivores accessed flesh, marrow, and/or grease from carcasses. Results validate the sensitivity of the models for inferring hominin feeding ecology, which have been questioned on grounds shown here to be unfounded. The bootstrapped feeding trace models are applied to the late Pliocene larger mammal fossil assemblage from FLK 22 (Zinjanthropus site), Olduvai Gorge, Tanzania. High frequencies of tooth and percussion marking on long bone midshaft fragments from FLK 22 are most consistent with those feeding trace models that simulate hominin scavenging from carcasses defleshed by carnivores, while cut mark data indicate that hominins more often had access to upper forelimb flesh than upper hind limb flesh. Together, the bone surface modification data indicate that hominins typically gained secondary access to partially defleshed carnivore kills, but they also allow for the possibility of some carcasses being processed only by carnivores and only by hominins.
