Prostrepsiceros and Protragelaphus (Artiodactyla,Mammalia) from the Late Miocene locality of Chomateri (Attica,Greece)

The Late Miocene fossiliferous locality of Chomateri is located close to the classic locality of Pikermi, but unfortunately its faunal context is not sufficiently known. Some fossil remains of spiral-horned antelopes from Chomateri are assigned to Prostrepsiceros rotundicornis and Protragelaphus skouzesi. The co-existence of P. rotundicornis and P. skouzesi is relatively rare in the Late Miocene, but well-documented in Pikermi. Comparisons of the Chomateri material support a middle Turolian age for the Chomateri locality and suggest a close chronological relation to the Pikermi fauna.     

Musteloids and feloids (Mammalia, Carnivora) from the late Miocene locality of Pikermi (Attica, Greece)

Some relatively rare carnivore remains from Pikermi are studied. The present specimens include Simocyon primigenius(ROTH and WAGNER, 1854), Promeles palaeatticus(WEITHOFER, 1888), Martes woodwardiPILGRIM, 1931, Felis atticaWAGNER, 1857 and Machairodus giganteus(WAGNER, 1848), as well as some postcranial remains that resemble Enhydriodon? latipesPILGRIM, 1931 and are assigned to Mustelidae gen. et spec. indet. Some of these species were not known until now but from their holotypes as M. woodwardi and E.? latipes. Other species such as F. attica and M. giganteus are better known but from relatively scant material. Since the material of the earlier mentioned species comes from Pikermi, their type locality, it is of especial importance and improves our knowledge for the Pikermi carnivores and their relationships to other species. In some cases where the material comes from ossiferous blocks, the accompanying faunal context is discussed.     

Proboscideans from the upper Miocene localities of Thermopigi,Neokaisareia and Platania (Northern Greece)

In the present article, we study the proboscidean remains from three upper Miocene localities of Northern Greece: Thermopigi (Serres), Neokaisareia (Pieria) and Platania (Drama). The material from the Turolian locality of Thermopigi includes only postcranial specimens. The morphological features of the scapula indicate the presence of the deinotheriid Deinotherium sp., whereas the rest of the specimens are morphologically distinct from Deinotherium and can be referred to Elephantimorpha indet. The material from Neokaisareia consists of a partial skeleton of a single individual and is attributed to the mammutid Mammut sp. (M. obliquelophus?). This taxon is known in Greece from the early–middle Turolian. The Platania proboscidean belongs to the tetralophodont amebelodontid Konobelodon cf. atticus. The genus Konobelodon was already present during the Vallesian of the wider area, but the lower tusk of the Platania shovel-tusker presents some morphological and metrical differences from the Vallesian representative, yet it has also smaller dimensions in its deciduous dentition than the morphologically similar Turolian specimens. The type locality of K. atticus is Pikermi (Attica, Greece), correlated to the middle Turolian, but the known biostratigraphic range of this species covers the entire Turolian. Platania is possibly correlated close to the Vallesian/Turolian boundary and the possible record of this species could document one of its earliest occurrences.     

<Emphasis Type="Italic">Mesopithecus</Emphasis> (Primates,Cercopithecidae) from the turolian locality of Vathylakkos 2 (Macedonia,Greece)

Two skulls, two mandibles and some postcranials ofMesopithecus from the locality “Vathylakkos 2” of Axios Valley (Macedonia, Greece) enlarge our knowledge about the genus and its differentiation. The new material together with an old skull from the same locality is compared with the Pikermi, “Ravin des Zouaves 5” (Axios Valley), and Maramena (Serres basin) samples. It is concluded that the VathylakkosMesopithecus resemblesM. pentelicus from Pikermi, as wellM. delsoni from “Ravin des Zouaves 5” and it is referred asMesopithecus sp. aff.M. pentelicus. The biochronological age of “Vathylakkos 2” has been considered as MN 12, while recent magnetostratigraphic data indicate an age of about 7.5 Ma. This age confirms the position of the VathylakkosMesopithecus between Pikermi and “Ravin des Zouaves 5”. Some dental indices compared with those of the RecentCercopithecus suggest that the Vathylakkos sample is monospecific.      

An almost complete skeleton of Metailurus parvulus (Carnivora, Felidae) from the late Miocene of Kerassia (Northern Euboea, Greece)

We describe a partial skeleton of Metailurus parvulus from the Turolian site of Kerassia 1 (Northern Euboea, Greece). The material, which consists of a mandible, the anterior and posterior limb-bone elements, some sternal bones and some vertebrae, is the most complete known of this species. The dental material is compared to specimens from Pikermi and Chomateri (Greece), and China. The limb-bones available offer us the possibility to discuss the status of some previously described specimens from Pikermi. The limb proportions indicate that M. parvulus had elongated posterior limbs relative to the anterior ones, which reflects developed jumping skills. M. parvulus had moderately developed cursorial abilities, intermediate between open and closed habitat felids, and probably frequented primarily relatively open woodlands.     

Poor but classic: The squamate fauna from the late Miocene of Pikermi,near Athens,Greece

I here describe new fossil remains of lizards and snakes from the late Miocene of Pikermi, near Athens, Greece. This classical locality, known since at least the middle of the 19th century, has yielded over the decades abundant mammal fossils, whereas squamate remains have been confined to early discoveries of Varanus remains during the 19th century. The first specimen among these varanid fossils, a large vertebra described by Albert Gaudry during the 1860s, represents also one of the earliest discoveries of a fossil monitor lizard worldwide. Nevertheless, this historically important specimen has only been briefly described and its so far only available images were the original lithographs and subsequent sketches of two only of its views. I here describe this specimen in detail and provide photographs of all its standard views. The additional squamate remains from the Pikermi area are fragmentary. Nevertheless, they document the presence in Pikermi of other lizard groups, such as lacertids and probable anguines, while snakes are described for the first time. Among the snake fossils, probable erycines and colubrids are identified; if indeed an erycine, this would be the oldest occurrence of that group in the Eastern Mediterranean, thus extending back its stratigraphic range in the area by several million years.     

The parrots (Aves: Psittaciformes) from the Middle Miocene of Sansan (Gers,Southern France)

The occurrence of Archaeopsittacus sp. (Psittaciformes) in the fossil deposits of Sansan (France) is reported, testifying to a survival of this genus in the Middle Miocene, as Archaeopsittacus verreauxi was described from the Early Miocene of Saint-Gérand-le-Puy (France) and was recorded only from its type locality. The data discussed here indicate the presence of two parrot species from Sansan, as it is the type locality of another parrot species, Pararallus dispar, only known from this locality. The differences between the humeri of these two taxa are described in detail, together with the differences from the other European fossil parrot species. The presence of more than one species of parrot in the same locality is not rare, but in Europe it is recorded in Sansan for the second time. Evidence for parrots also confirms the paleoenvironmental reconstruction of Sansan, as parrots are primarily arboreal species. Archaeopsittacus also represents one of the few common elements between the Early and Middle Miocene European bird assemblages.     

Ademosynoides asiaticus Martynov, 1936, the earliest known member of an extant beetle family (Insecta, Coleoptera, Trachypachidae)

Fossil beetles are described from Kedrovka beds of the locality Babii Kamen’, Kuznetsk Basin, Siberia. According to different authors, this locality is dated to the terminal Permian or basal Triassic. SEM studies have shown that Ademosynoides asiaticus Martynov, 1936, described from this locality, should be placed in the family Trachypachidae, which makes it the earliest known extant family of beetles. In addition to the re-studied holotype, further material is described for this species; a new species of the same genus and a new genus and species of the same family are also described. As a result, almost 10% of the 78 beetle fossils known from this locality are identified as belonging to Trachypachidae. Unfortunately, the study of these beetles is complicated by the rather poor preservation quality and very small size of the majority of the fossils, which usually cannot be properly studied without using SEM. However, even in this case there is no full certainty that the results are absolutely reliable.     

First giraffid skulls (Bohlinia attica) from the late Miocene Maragheh fauna,Northwest Iran

An almost complete skull and a second partial skull of Bohlinia attica (Artiodactyla: Giraffidae) from the late Miocene of Maragheh in northwestern Iran is described along with a complete upper dentition from Samos in Greece. These specimens enrich what is known of this species. The skull has massive bent ossicones. The braincase is horizontal to the face in lateral view. The upper premolars have strongly curved styles. The metapodials of this species are elongate with a deep plantar trough. The braincase is short and the occipital does not extend caudally. The type material of Bohlinia is from Pikermi but this taxon is also known from localities in F.Y.R.O. Macedonia, Greece, Turkey, Bulgaria, Iraq, and Iran. The new specimens are similar to others except that the ossicone terminates in a knob and the palatine choanae are positioned caudally. This taxon along with Honanotherium, which is most similar but with shorter metapodials and simpler premolars, can be placed in the subfamily Bohlininae.     

Ancylotherium pentelicum (Perissodactyla, Mammalia) from the Upper Miocene of central and western Turkey

We report here new fossils of A. pentelicum from two Turolian localities of central and western Turkey, Pinaryaka and Salihpasalar (Kemikalan). The material, which consists of well preserved distal limb-bones, is compared with the few previously described specimens, mainly from Samos and Pikermi, but the observed differences should probably be attributed to individual variation. There is no evidence of evolution of the species during the Middle Turolian of the eastern Mediterranean, where it filled a narrow ecological niche, before its extinction.     

Fossil frogs (Anura) from Shanwang (Middle Miocene; Shandong Province, China)

The early middle Miocene biota from the Shanwang locality in eastern China is one of the most diverse and well preserved in the world. This overall richness contrasts with its low diversity of anuran amphibians. The most abundant anurans are representatives of the family Ranidae, which remains the dominant group in the extant anuran fauna of China. Besides Rana basaltica Young, some other ranids can be recognised at the locality, and are clearly distinguishable from R. basaltica based on their larger size and different proportions. Ranids are also represented by a developmental series of tadpoles, ranging from approximately Nieuwkoop-Faber (NF) stage 43 to a metamorphosing tadpole of NF stage 57. This is the first known developmental series of fossil non-pipoid Anura outside the Pelobatidae. In addition to the ranids, Bufo shandongensis nov. sp. (replacement name for B. linquensis), represented by one of the earliest known articulated bufonid skeletons, is described and illustrated. Another large toad, Macropelobates linquensis (Yang) nov. comb., is re-described; it can be assigned to the Pelobatoidea, with a possible relationship to the Scaphiopodidae, and can be considered, based on the presence of a large spade, a tibiofibula shorter than the femur, and a short astragalus and calcaneus, to be the earliest known anuran burrower.     

A skull of Mesopithecus with bite marks (author's transl)

A skull of Mesopithecus pentelicus (Roth and Wagner) from the Turolian (Upper Miocene) of Pikermi (Greece) shows hole-shaped bitemarks. Considering the behavior and the character of the dentition of the groups of carnivores represented in Pikermi, it is supposed that these bitemarks have been caused by a felid of the size of a leopard. In the fauna of Pikermi only Metailurus parvulus (Hensel) can be taken into consideration. By the defects on a skull of a juvenile Australopithecine, interpreted by Brain in 1970 as bitemarks of a leopard, the above explanation gets a very essential support.     

Calcaneal features of the Greek Miocene primate Mesopithecus pentelicus (Cercopithecoidea: Colobinae)

This paper investigates substrate preferences of the Greek Colobine Mesopithecus pentelicus WAGNER, from the Miocene of Pikermi, by examining selected functional features of the calcaneus that distinguish between arboreal and terrestrial Cercopithecidae. Mesopithecus possesses a relatively long proximal calcaneal region associated with a slightly low and wide surface for the insertion of m. triceps surae. These features approximate that of semi-terrestrial Cercopithecidae and would suggest terrestrial cursorial activities. On the other hand, the relatively long and narrow proximal calcaneo-astragalar facet, similar to that of most arboreal species, would provide ampler subtalar movements. The mosaic of these features implies a semi-terrestrial way of life and conforms to the savanna-woodland paleoenvironment of Pikermi, Greece. These features appear to be well associated with foot function and change of habitus and are used to examine scenarios of the evolutionary history of the Colobinae.     

Neocometes (Rodentia,Platacanthomyinae) from the early Miocene of Echzell,Germany

The dental material described in this paper represents the largest known sample of molar material of the extinct platacanthomyine rodent Neocometes Schaub and Zapfe. It can be attributed to Neocometes similis Fahlbusch, the stratigraphically oldest and most primitive of the two species recognized in the European Miocene. This rich material provides sufficient samples of all molar positions to evaluate and confirm the morphologic and morphometric characters given for N. similis. The evolutionary stage of the Neocometes population from Echzell is only slightly more derived than the one from the type locality Erkertshofen 2, and supports the biostratigraphic setting of Echzell given by earlier authors. N. similis is the first mammal described in detail from the fossiliferous ash layers of Echzell, a locality situated at the southwestern margin of the Vogelsberg volcanic complex in central Germany.     

NewLiparis species (Orchidaceae) from South Central and East Africa

Liparis molendinacea is related toL. deistelii and known so far only from the type locality in Kawambwa district in the Northern Province of Zambia.L. nyikana likewise is related toL. deistelii, it is distributed in E. and SW. Tanzania and in N. Malawi.L. chimanimaniensis is related toL. nervosa and known so far only from the Chimanimani Mountains in the Eastern Province of Zimbabwe.     

New material of Chalicotheriidae (Perissodactyla,Mammalia) from the Late Miocene of Axios Valley,Macedonia (Greece) with the description of a new species

Chalicotheriids are rare in the late Miocene mammal localities of Axios Valley, Macedonia (Greece). The new campaign of excavations, since 1972, has provided some specimens, which are studied in this article. They are coming from two different localities. The late early Vallesian locality of Pentalophos 1 (PNT) has provided a skull and a mandible of an Ancylotherium. The morphological characters of the PNT material as the small size, the long snout, the shallow mandibular corpus, the strong cingulum in the teeth, the short tooth rows and the short M3/m3 indicate that it differs from the known Turolian species A. pentelicum and allow the erection of a new species, named Ancylotherium hellenicum n. sp., which can be used as a biostratigraphic marker of the Vallesian. The middle Turolian locality Prochoma 1 (PXM) has provided only one M3, which is determined to the chalicotheriine Anisodon macedonicus. This species was earlier described from the middle Turolian locality Vathylakkos 3 (VAT) and the late Turolian one of Dytiko 3 (DKO) of Axios Valley. The biogeography and biostratigraphy of the late Miocene chalicotheres of the Greco-Iranian Palaeoprovince (GRIP), as well as their palaeoecology are also discussed. The common chalicothere of GRIP is A. pentelicum, expanded from the Balkans to Afganistan and ranging stratigraphically from the early to the late Turolian. Chalicotherium goldfussi is certainly present in GRIP and it also ranges from the early to the late Turolian; its possible Vallesian occurrence needs confirmation. The other two late Miocene chalicotheres of GRIP A. macedonicus and Kalimantsia bulgarica are restricted to the Turolian of the Balkan Peninsula.     

The presence ofsus strozzii in the villafranchian (villanyian) of macedonia (greece)

The locality of Gerakarou is a new Pleistocene one in Macedonia (Greece) found in 1978. Between the material recovered there is a suid skull, which is studied in this article. Its morphological characters and dimensions allow us to determine this asSus strozzii Forsyth Major. It seems to be similar to the Upper Valdarno and Olivola suids and different from the other Villafranchian suid,Sus minor. Thus it is dated to Late Villafranchian (Villanyian). The certain presence of the species in Greece, where it was known only from some isolated specimens referred asSus cf.strozzii, completes the knowledge of the geographic distribution of the species in Southern Europe.     

A new hipparion (Mammalia,Perissodactyla) from the Vallesian (Late Miocene) of Greece

A small hipparion from the Vallesian (early Late Miocene) of Northern Greece is studied. It is coming from the locality “Ravin de la Pluie” of the lower Axios valley, near Thessaloniki. Its characteristics as the small size, the short symphysis, the long snout, the high enamel plication, the well developed protostylid, the large m₃ and the elongated m₁-m₃ series distinguish it from the other known eurasiatic small hipparions, allowed us to derive a new species,Hipparion macedonicum. It lived during Vallesian and can be used as a stratigraphic species for this period.     

Observations on the Turin specimen ofMesopithecus pentelici (Wagner, 1839)

A fossil specimen ofMesopithecus pentelici Wagner, 1839, from the Pikermi paleontological assemblage and currently housed at the Geological Museum of the Earth Sciences Department of the University of Turin, is described herein. The left mandibular ramus displays dental features which permit us to assign it to a young female individual. Anatomical patterns are discussed and are compared with other similar remains of more recent discovery.
