The Eocene pufferfish genus Eotetraodon (Tetraodontidae) has previously been known only on the basis of E. pygmaeus (Zigno, 1887) from the lowermost Middle Eocene of Monte Bolca, Italy. To Eotetraodon we now add E. gornylutshensis sp. nov. from the uppermost Middle Eocene of the Kuma Horizon of the northern Caucasus (Gorny Luch locality). E. gornylutshensis sp. nov. differs from E. pygmaeus by having much longer ribs and one less vertebra in the caudal peduncle.  相似文献

Fragmentary remains of sea turtles (Cheloniidae sensu lato: Argillochelys sp., Puppigerus nessovi Averianov, 2005, and Cheloniidae gen. indet.) from the Ikovo locality (Lugansk Region, Ukraine; Lower Lutetian, Middle Eocene) are described. The genera Argillochelys and Puppigerus are recorded for the first time in Eastern Europe. The turtle assemblage from Ikovo is similar at the generic level to West European assemblages (Belgium, Great Britain) of approximately the same age (Lower-Middle Eocene). In the presence of P. nessovi, the Ikovo assemblage is similar to that from the Middle Eocene Dzheroi 2 locality (Uzbekistan).  相似文献

Early Paleogene insectivore mammal associations of Asia include true insectivores (superorder Insectivora: order Lipotyphla: suborders Erinaceomorpha and Soricomorpha; orders Didymoconida and Leptictida) and insectivore-like placentals (superorder Ferae: order Cimolesta: suborders Didelphodonta, Palaeoryctida, and Pantolesta). The associations from Mongolia are the most taxonomically diverse. The Late Paleocene association from the Zhigden Member of the Naran-Bulak Formation of the Tsagan-Khushu and Naran-Bulak localities includes the following soricomorph insectivores: the micropternodontid Sarcodon pygmaeus Matthew et Granger and Hyracolestes ermineus Matthew et Granger (Sarcodontinae), the geolabidid Gobigeolabis verigranum Lopatin, the nyctitheriid Praolestes nanus Matthew, Granger et Simpson, P. maximus Kondrashov, Lopatin et Lucas (Praolestinae subfam. nov.), Jarveia erronea Kondrashov, Lopatin et Lucas (Asionyctiinae). Moreover, the Zhigden association includes the didymoconid Archaeoryctes euryalis Lopatin (Ardynictinae), the palaeoryctid Pinoryctes collector gen. et sp. nov., and the pantolestid Zhigdenia nemegetica gen. et sp. nov. (Pantolestinae). The Early Eocene association from the Bumban Member of the Naran-Bulak Formation of the Tsagan-Khushu locality includes the micropternodontid Prosarcodon maturus Lopatin et Kondrashov (Sarcodontinae); the nyctitheriids Bumbanius rarus Russell et Dashzeveg (Praolestinae), Oedolius perexiguus Russell et Dashzeveg, Edzenius lus gen. et sp. nov. (Asionyctiinae), and Eosoricodon terrigena Lopatin (Eosoricodontinae); the plesiosoricid Ordolestes ordinatus gen. et sp. nov. (Butseliinae); and the cimolestids Naranius infrequens Russell et Dashzeveg, Tsaganius ambiguus Russell et Dashzeveg, and Bagalestes trofimovi gen. et sp. nov. (Cimolestidae). The Middle Eocene association from the Khaychin Formation of the Khaychin-Ula 2 and Khaychin-Ula 3 localities includes the erinaceomorphs Eogalericius butleri Lopatin and Microgalericulus esuriens gen. et sp. nov. (Erinaceidae, Galericinae), the soricomorphs Metasarcodon reshetovi Lopatin et Kondrashov (Micropternodontidae, Sarcodontinae), Soricolestes soricavus Lopatin (Soricidae, Soricolestinae), and Asiapternodus mackennai Lopatin (Apternodontidae, Asiapternodontinae subfam. nov.); the didymoconids Ardynictis captor Lopatin (Ardynictinae), Khaichinula lupula gen. et sp. nov. (Didymoconinae), Kennatherium shirense Mellett et Szalay, and Erlikotherium edentatum gen. et sp. nov. (Kennatheriinae subfam. nov.); and the palaeoryctid Nuryctes gobiensis Lopatin et Averianov (Palaeoryctidae). Late Paleocene insectivores from the Dzhilga 1a locality (Kazakhstan) comprise the nyctitheriids Voltaia minuta Nessov and Jarveia minuscula Nessov (Asionyctiinae). The faunal assemblage dated terminal Early Eocene from the Andarak 2 locality (Kyrgyzstan) includes the micropternodontid Metasarcodon udovichenkoi (Averianov), the erinaceid Protogalericius averianovi gen. et sp. nov. (Galericinae), and the palaeoryctids Nuryctes alayensis Lopatin et Averianov and Palaeoryctidae gen. et sp. indet. From the end of the Paleocene to the onset of the Middle Eocene, the taxonomic composition and ecological structure of insectivore communities of Central Asia gradually changed, insectivore-like placentals and primitive soricomorph groups were replaced by the Recent families of Lipotyphla. The morphological and evolutionary study of Early Paleogene Asian insectivores has provided important data on phylogenetic relationships of the Insectivora. The family Micropternodontidae is divided into the subfamilies Sarcodontinae and Micropternodontinae. The earliest insectivore family Geolabididae is recorded in the Paleogene of Asia. A new classification of the family Nyctitheriidae, dividing it into the subfamilies Nyctitheriinae, Amphidozotheriinae, Asionyctiinae, Eosoricodontinae, and Praolestinae subfam. nov., is proposed. Based on the morphological continuity between Eosoricodontinae (Nyctitheriidae) and Soricolestinae (Soricidae), the family Soricidae is proposed to originate from eosoricodontine nyctitheriids. The family Plesiosoricidae is divided into the subfamilies Butseliinae and Plesiosoricinae. A new subfamily, Asiapternodontinae subfam. nov., is established in the family Apternodontidae. The analysis of evolutionary transformations of the dental system suggests the continuity of molar types in the suborder Soricomorpha, which supports the validity of the infraorders Tenrecomorpha and Soricota (the latter includes the superfamilies Micropternodontoidea, Nesophontoidea, Soricoidea, Talpoidea, and Solenodontoidea). The subfamily Galericinae (Erinaceidae) is recorded in Asia at the Early-Middle Eocene boundary. The family Didymoconidae is divided into the subfamilies Ardynictinae, Didymoconinae, and Kennatheriinae subfam. nov. Some members of the subfamily Kennatheriinae display a clear edentate functional pattern, which is atypical for insectivores and is interpreted as an adaptation for feeding on colonial insects. The following scenario of insectivore evolution, describing the major stages of their history, is proposed: (1) in the first half of the Late Cretaceous, the first occurrence of Insectivora (probably in North America); (2) in the second half of the Late Cretaceous, the primary radiation of Insectivora, establishment of Leptictida, Didymoconida, and Lipotyphla; detachment of Erinaceomorpha and Soricomorpha; (3) at the Cretaceous-Paleocene boundary, the primary radiation of Soricomorpha and establishment of Tenrecomorpha (Africa) and Soricota (North America); (4) in the Paleocene, expansion of Soricota in the Northern Hemisphere, the primary radiation of Erinaceomorpha, and emergence of Erinaceidae (North America); (5) at the Paleocene-Eocene boundary, radiation of Soricota and Erinaceidae; (6) at the Early-Middle Eocene boundary, appearance of Soricidae, Talpidae, and Galericinae; (7) in the Middle Eocene-Oligocene, replacement of primitive groups by Recent families and related groups and the formation of the Recent subfamilial diversity of the families Soricidae, Talpidae, Erinaceidae, and Tenrecidae; (8) in the Miocene-Pliocene, disappearance of primitive groups of the Recent families, a decrease in the diversity of Erinaceomorpha, extensive radiation of Soricidae and the formation of the Recent generic diversity of insectivores.  相似文献

Beetle remains from the Triassic Khey-Yaga locality, Nenets National District, Korotaikha Basin, Nyadeita Formation, Olenekian-Anisian are described. Only isolated elytra have been found. Tetracoleus tshalyshevi gen. et sp. nov. and T. minimus sp. nov. are described and assigned to Tricoleidae, and six new species are described in formal taxa. Tetracoleus is close to Permian tricoleids just found in the Newcastle Group of Australia and the Vyatkian Aristovo locality of northern European Russia. The composition of elytra in the locality is closer to that of Lower Triassic localities than other Middle Triassic localities and characterizes the beginning of a recovery after the Permian-Triassic ecological crisis. Longxianocupes Hong in Liu, Liu et Hong, 1985 is shown to be a junior synonym of Sogdelytron Ponomarenko, 1969. The species Palademosyne ovum Ponomarenko, 2004, P. elongatum Ponomarenko, 2004, and P. latum Ponomarenko, 2004 are transferred to the genus Pseudochrysomelites Handlirsch, 1906.  相似文献

Until now, the earliest known members of the triggerfish family Balistidae have been two genera from the Oligocene. Herein is described the new balistid Gornylistes prodigiosus gen. et sp. nov. from the uppermost Middle Eocene (Kuma Horizon) of the Northern Caucasus (Gorny Luch locality); it is as thoroughly modern in its bauplan as the taxa of balistids from the Oligocene and more recent periods, and far more advanced morphologically than the several stem taxa of the balistoid + ostracioid clade known from earlier in the Middle and Lower Eocene and from the Upper Paleocene.  相似文献

The earliest member of an extant ant genus of the subfamily Myrmicinae, Aphaenogaster dlusskyana sp. nov., from the Sakhalin amber (Russia, Middle Eocene, 43–47 Ma) is described. Fossil representatives of the genus Aphaenogaster are critically analyzed and it is proposed to transfer many of these to the fossil morphotaxon Paraphaenogaster. The morphology, distribution, and possible evolutionary trends of the genus Aphaenogaster are reviewed and it is suggested that this genus appeared in the territory currently occupied by the Palearctic not later than the Early Eocene (over 50 Ma). Aphaenogaster dlusskyana can be considered the oldest described representative of an extant genus of the subfamily Myrmicinae, although earlier, as yet undescribed, records of extant genera of Myrmicinae belong to the Early Eocene.  相似文献

The oldest representative of the family Entelodontidae (suborder Suiformes), Proentelodon minutus gen. et sp. nov, is described from the Middle Eocene Khaichin Ula II Fauna in Mongolia. In addition to the genus Proentelodon, the new subfamily Proentelodontinae includes the genus Eoentelodon from the Middle-Upper Eocene of China, Mongolia, and Kazakhstan. The new data bring clues to the origin and systematic position of Entelodontidae, features of their evolution, dispersal, and changes in taxonomic diversity. They also elucidate the early evolutionary stages of Suiformes.  相似文献

A new genus, Tologuica, with two species (T. aurorae sp. nov. and T. karhui sp. nov.), from the Middle Miocene of the Sharga locality (western Mongolia) is described. The new genus shares some characters with the extinct genera Palaeocryptonyx, Palaeortyx, and Plioperdix and with extant Coturnix. The foot structure suggests that Tologuica resembled in ecology the European genus Palaeortyx and was probably adapted to an arboreal mode of life, in contrast to the terrestrial Coturnix and Plioperdix.  相似文献

The genus Riasanites, represented in Central Russia by two successive dimorphic species, is revised. R. swistowianus is found in the basal beds of the rjasanensis Zone. Its descendant R. rjasanensis is also found in this zone, but upwards in the section, including the beds with Surites spasskensis and Externiceras solowaticum. The representatives of Riasanites from the Crimea and Northern Caucasus are assigned to two species, R. crassicostatus and R. maikopensis, respectively. It is suggested that Riasanites evolved from Sub-Mediterranean Himalayatidae, which migrated from the Western Tethys via the Polish Passage into the Central Russian Basin, and from there to Mangyshlak, the Northern Caucasus, and the Crimea.  相似文献

The fauna of grass flies (Diptera: Chloropidae) of the Crimean Peninsula is reviewed for the first time. The study is based on examination of the collection of the Zoological Institute, Russian Academy of Sciences (St. Petersburg), which includes the material collected in Crimea by the authors, the collections of the Zoological Museum of the M. V. Lomonosov Moscow State University and V. I. Vernadsky Crimean Federal University (Simferopol). The annotated list includes 92 species in 34 genera and three subfamilies. Most of the species (61) are recorded from Crimea for the first time. Six species, Chlorops horridus Becker, Ch. puncticornis Loew, Dicraeus (Oedesiella) beschovskii Nartshuk, Lasiosina chandleri Ismay, Meromyza meigeni Nartshuk and Oscinimorpha longirostris (Loew) are recorded for the first time from Russia and Eastern Europe. The characters for distinguishing Oscinimorpha arcuata Duda from O. longirostris (Loew), i.e., the structure of head and the male genitalia, are provided. The boreo-montane species Oscinella vastator (Curtis) and Meromyza curvinervis (Zetterstedt) are found on the Chatyrdag Mountain and Yaila (mostly forestless plateau in the Crimean Mountains). Species with southern European, Mediterranean and Macaronesian-Mediterranean ranges were recorded mostly on the South Coast of Crimea. The Crimean fauna of Chloropidae is compared with the faunas of Sardinia and Turkey.  相似文献

Upper Triassic Norian reef boulders, exposed in a locality near the fountain “Tavuk Cesme” (“Chicken Fountain”) in Taurus Mountains, southern Turkey yielded a large number of hypercalcified sponges, including “sphinctozoans”, “inozoans”, “spongiomorphids”, and “chaetetids”. The sphinctozoans from this locality are described in this paper. Geologically, this locality belongs to the Anamas-Akseki autochthonous. The reef boulders of this locality are exposed near the “Tavuk Cesme” fountain, located at the road, leading from the town of Aksu to Yenisarbademli. The following taxa are described: Amblysiphonella taurica nov. sp., Anthalythalamia riedeli Senowbari-Daryan, Calabrisiphonella sphaerica nov. sp., Calabrisiphonella cuifi nov. sp., Cinnabaria minima Senowbari-Daryan, Colospongia recta nov. sp., Colospongia sp. 1, Colospongia sp. 2, Colospongia sp. 3, Cryptocoelia compacta nov. sp., Cryptocoelia? sp., Deningeria crassireticulata Senowbari-Daryan, Zühlke, Bechstädt and Flügel, Discosiphonella minima Senowbari-Daryan and Link, Gigantothalamia ovoidalis Senowbari-Daryan, Hajarispongia dipoyrazensis nov. sp., Hajarispongia cortexifera nov. sp., Kashanella irregularis Senowbari-Daryan, Kashanella cylindrica nov. sp., Parauvanella ferdowsensis Senowbari-Daryan, Parastylothalamia cylindrica nov. gen., nov. sp., Asiphothalamia polyosculata nov. gen, nov. sp., Sollasia norica nov. sp., and Thaumastocoelia sphaeroida Senowbari-Daryan. The most abundant sponge is Amblysiphonella taurica nov. sp. followed by Hajarispongia dipoyrazensis nov. sp., Colospongia and Discosiphonella minima Senowbari-Daryan and Link are also relatively abundant. The stylothalamid sponge Parastylothalamia nov. gen. is an abundant sponge genus in other Norian reefs of the Taurus Mountains, but is rare at the “Tavuk Cesme” locality.  相似文献
