Gobiocerus mongolicus Sokolov, 1952, Turcocerus kekemaidengensis Ye Jie et al., 1999; and Hypsodontus sp. were recorded in Miocene deposits of the Valley of Lakes (MN4-MN8) and Oioceros atropatenes (Rodler et Weithofer, 1890) occurred in the Mio-Pliocene (MN11-MN20) of northwestern Mongolia. Gobiocerus, Turcocerus, and Hypsodontus represent the same evolutionary lineage. Thus, Caprinae existed in Central Asia in the Early Miocene. They diverged from the Bovidae at the Oligocene-Miocene boundary. The presence of early bovids in this region suggests that this group could have appeared in Central Asia.  相似文献

New taxa of Orthoptera Ensifera are described in the families Mogoplistidae [Protomogoplistes asquamosus gen. et sp. nov. (Upper Cretaceous) in the subfamily Protomogoplistinae subfam. nov. and Archornebius balticus gen. et sp. nov. (Eocene), Pseudarachnocephalus gen. nov., P. dominicanus sp. nov., and P. latiusculus sp. nov. (all Miocene) in Mogoplistinae] and Gryllidae [Eopentacentrus borealis gen. et sp. nov. (Eocene), ?Grossoxipha feminea sp. nov. (Miocene), and Apentacentrus copalicus sp. nov. in the subfamily Pentacentrinae, ?Cyrtoxipha electrina sp. nov. and ?Cyrtoxipha illegibilis sp. nov. (both Miocene) in Trigonidiinae, and Baltonemobius fossilis gen. et sp. nov. (Eocene) in Nemobiinae]. The Miocene genera Proanaxipha Vickery et Poinar and Grossoxipha Vickery et Poinar are transferred from the subfamily Trigonidiinae to Pentacentrinae. P. latoca Vickery et Poinar and Abanaxipha longispina Vickery et Poinar are redescribed; the male of the latter species is described for the first time.  相似文献

In the late Miocene deposits in the Taralik–Cher locality (Tuva Republic), fossil remains of a giant mustelid of the genus Eomellivora Zdansky, 1924 have been found. This finding is the first reliable evidence of the Eomellivora inhabiting the modern Russia. Teeth of the Eomelliovra from Taralik–Cher are similar in size to those of E. wimani and E. piveteaui from the late Miocene in Eurasia. The morphology of teeth of the material from Tuva is most similar to that of E. ursogulo; therefore, it is considered a small form of Eomellivora ursogulo. The described finding expands the understanding of diversity, variability, and distribution of representatives of the genus Eomellivora in Asia during the late Miocene.  相似文献

The Thinodromus lunatus species group is revised. The following new species are described: Thinodromus (s. str.) cattiensis sp. n. from Vietnam, Thinodromus (s. str.) forsteri sp. n. from southern Thailand, Thinodromus (s. str.) himalayensis sp. n. from Nepal and northern India, Thinodromus (s. str.) inconspicuus sp. n. from southern China, Thailand, and Vietnam, and Thinodromus (s. str.) spotus sp. n. from southern China. The following new synonymy is established: Thinodromus (s. str.) deceptor (Sharp, 1889) = Thinodromus (s. str.) gravelyi (Bernhauer, 1926), syn. n.; = Thinodromus (s. str.) reitterianus (Bernhauer, 1938), syn. n. Lectotypes are designated for Trogophloeus lunatus Motschulsky, 1857, Trogophloeus pustulatus Bernhauer, 1904, Trogophloeus socius Bernhauer, 1904, Trogophloeus sumatrensis Bernhauer, 1915, Trogophloeus lewisi Cameron, 1919, Trogophloeus gravelyi Bernhauer, 1926, Trogophloeus reitterianus Bernhauer, 1938, and Trogophloeus unipustulatus Cameron, 1941. A key is presented to all the species of the Thinodromus lunatus group.  相似文献

The phasianid genera Perdix, Plioperdix, and Bantamyx from the Neogene of Mongolia and Transbaikalia are reviewed. Based on published data and new material, the diagnoses of Late Pliocene Perdix margaritae Kurochkin and Plioperdix ponticus (Tugarinov) and Late Miocene Bantamyx georgicus Kurochkin are emended. It is shown that a tarsometatarsus from the Upper Miocene of the Pavlodar locality belongs to the genus Palaeoperdix rather than Palaeortyx, as was proposed in the previous studies. Small Neogene Asian phasianids are compared in detail with Neogene taxa from Europe and extant genera.  相似文献

Ant imprints, new and previously known, from Middle Miocene deposits near Kerch (Crimean Peninsula, Russia) are described or redescribed. A new Myrmicinae species, Solenopsis atavinus sp. nov., is described based on a wingless female. A winged female similar to the earlier described Dolichoderus tauricus Dlussky, 1981 is found: due to the excellent preservation of this specimen, the new specimen and the holotype of D. tauricus are redescribed and can be reclassified as Ponerites tauricus (Dlussky, 1981), comb. nov. Oecophylla taurica sp. nov. is described based on a partly preserved imprint of a female thorax with a forewing, the venation of which allows it to be positively identified as a weaver ant. Two other species are transferred from the formal genus Camponotites to Oecophylla based on forewing venation: O. kraussei (Dlussky et Rasnitsyn, 1999), comb. nov. (Early Eocene, United States) and O. macroptera (Dlussky, 1981), comb. nov. (Middle Miocene, Stavropol, Russia). One of the studied forewing imprints is similar in venation to Paraphaenogaster microphthalmus Dlussky, 1981, described from the Middle Miocene of Vishnevaya Balka (Stavropol province, Russia) and so is attributed to this species. Dolichoderus tavridus sp. nov. is described based on a forewing.  相似文献

New taxa of the suborder Blattina (order Dictyoptera), possibly belonging to the family Corydiidae (Erucoblatta semicaeca gen. et sp. nov., Miocene; Proholocompsa gen. nov., Eocene; and Holocompsa nigra sp. nov. and H. abbreviata sp. nov., Miocene) and belonging to the family Ectobiidae (Plectoptera electrina sp. nov., Miocene; Agrabtoblatta symmetrica gen. et sp. nov. and ?Symploce rete sp. nov., Pleistocene) are described. The taxonomic position of the enigmatic genus Raphidiomimula Grimaldi et Ross from the Upper Cretaceous is discussed.  相似文献

From the Bavarian Early/Middle Miocene (MN5) site Sandelzhausen, nine species of carnivoran mammals are identified including the hemicyonine ursid Hemicyon stehlini, the amphicyonids Amphicyon cf. major and Pseudarctos bavaricus, the mustelids Ischyrictis zibethoides and Martes cf. munki, the mephitid Proputorius pusillus, the viverrid Leptoplesictis cf. aurelianensis, the felid Pseudaelurus romieviensis, and finally the recently described barbourofelid Prosansanosmilus eggeri. With these taxa present, Sandelzhausen shows a carnivoran community typical, though deprived, for the Lower to Middle Miocene of Europe, but different from roughly contemporary Mediterranean faunas such as those from Çandir or Pa?alar in Turkey.  相似文献

Remains of fishes, turtles, birds, and mammals are described from the Upper Miocene (MN13) Shkodova Gora locality (Ukraine, Odessa Region), the only representative locality of Pontian large vertebrates in the northwestern Black Sea Region. Asiatic fish and avian taxa are recorded for the first time in the Upper Miocene of Europe. The Shkodova Gora ichthyofauna includes eight freshwater fish species (belonging to Acipenseridae, Cyprinidae, Siluridae, and Percidae). Taxa that have previously been recorded only in Western Siberia (Abramis bliccoides, Perca lepidopoma), eastern Kazakhstan, and the Altai Mountain (Rutilus tungurukensis) are revealed. Acipenser gueldenstaedtii is recorded for the first time in the Upper Miocene of Eastern Europe. The occurrence of the genus Ctenopharyngodon, a member of the Chinese plain faunal assemblage is of great interest. The Shkodova Gora avifauna (seven taxa) is mostly composed of waterfowl, including Phalacrocorax mongoliensis, which has previously been known only from the Lower Pliocene of Mongolia. The finding of Proanser major is the youngest record of this species in the fossil record. Mammals of the Shkodova Gora association include a hare resembling Trischizolagus dumitrescuae, Palaeoryx cf. pallasi, and Hipparion cf. moldavicum, which have not been mentioned among Pontian taxa of the northern Black Sea Region. Pontian paleolandscapes in the area of the Shkodova Gora locality are reconstructed.  相似文献

A new species, Betula erkovetskiensis Blokhina et O.V. Bondarenko (Betulaceae), from the deposits of the Sazanka Formation (upper Middle?Upper Miocene) of the Erkovetskii Brown Coal Field (Amur Region, Russia) is described based on anatomical features of fossil wood. The new species shows some wood anatomical characters of the extant birch subgenus Betula, B. davurica, B. nigra (section Dahuricae), and B. papyrifera (section Betula). Fossil wood of Betula is found in the Amur Region for the first time.  相似文献

The distribution of the allochthonous crab Percnon gibbesi and its relationships with other benthic invertebrate species was assessed inside the marine reserve of Cabo de Palos—Islas Hormigas (Mediterranean sea, Spain) and neighbouring non-protected sites. Although a significant spatial variability was detected at finer spatial scale, there was no influence of protection measures or insularity on the abundance of P. gibbesi. The presence of small holes, encrusting algae and low slope favour the colonization success of this crustacean, and the spatial distribution of these habitat features could explain the observed pattern. The abundance of P. gibbesi was similar to that of native crab species; however, a non-significant negative relationship between the abundance of P. gibbesi and native crabs (Pachygrapsus marmoratus and Eriphia verrucosa), urchins (Arbacia lixula and Paracentrotus lividus) and a snail (Phorcus turbinatus) was observed. This work highlights the importance of monitoring alien crab population densities taking structural habitat and other potentially influential factors into account and the likely effect of this alien species on the native ones.  相似文献

A new species, Laricioxylon erkovetskiense sp. nov. (Pinaceae) identified on the basis of anatomical features of fossil wood from the Sazanka Formation (upper Middle Miocene–Upper Miocene) of the Erkovetskii Brown Coal Field (Amur Region) is described. The new species shares some characters with the extant larches Larix cajanderi and L. olgensis.  相似文献

In the present work, we provide muscular reconstruction and we infer functional properties of the forelimb of Plesiotypotherium achirense, a fossil mesotheriid notoungulate from the late Miocene of Achiri (Bolivia). This locality has yielded the widest sample ever available for the forelimb of a mesotheriid. In addition, we propose a qualitative comparison of the forelimb (osteology and myology) at the family level, including the Miocene–Pleistocene mesotheriines Mesotherium cristatum, Plesiotypotherium achirense, Caraguatypotherium munozi, Plesiotypotherium casirense, and Pseudotypotherium sp, and the late Oligocene trachytheriine Trachytherus alloxus. Functional properties are consistent with a digging ability and a “scratch-digger” lifestyle for Mesotheriidae. In general, there are only slight differences among the comparison sample, except for Mesotherium cristatum, which reflect significant osteological modifications, likely to help increasing the moment arm while scratch-digging. These features are mainly observable on scapulae (distal border caudally displaced) and humeri (deltoid crest distally oriented and crista supracondylaris lateralis laterally projected).  相似文献

Two new species of the family Derbidae are described. Anticedusa gen. n. (tribe Cedusini) includes the recent A. loisae sp. n. (type species) from Costa Rica and A. dominicana sp. n. from the Miocene Dominican amber. Cedochrusa gen. n. (type species Cedusa quixoa Kramer from Panama) of the tribe Cedochreini also contains a new species, Cedochrusa luculenta sp. n. from Costa Rica. A new subtribe Eocenchreina subtrib. n. comprising genera Eocenchrea Muir, Melusa Em., and Anticedusa gen. n. is erected for Cedusini with the achilid venation of the clavus.  相似文献

The modern New Zealand flora has a relatively low number of families and genera in relation to land area, but well-preserved macrofossils and pollen from three sites in southern New Zealand suggest that the floras in Eocene, Oligocene and Miocene times were much more diverse at the generic level. At Pikopiko, Southland, a late Eocene in situ forest with fern understory was dominated by conifers, Casuarinaceae, Lauraceae, Nothofagus, Proteaceae, and mesothermal angiosperms including palms (aff. Calamus), Sapindaceae: Cupaniae and Picrodendraceae. At Newvale Mine, Southland, a leaf bed within a thick lignite seam represents leaf fossils preserved in a late Oligocene oligotrophic bog. This site demonstrates that Agathis, Dacrycarpus, Dacrydium, Halocarpus, Microcachrys, Podocarpus and Phyllocladus coexisted with diverse angiosperms including Nothofagus, Gymnostoma, Cunoniaceae, Ericaceae, Sapindaceae and several Proteaceae. Pollen data add Meliaceae, Myrtaceae, Onagraceae and Rubiaceae to the flora. At Foulden Maar, Otago, mummified leaves and flowers, including several with in situ pollen, demonstrate the existence of a diverse flora surrounding an Early Miocene lake. This site contains numerous monocot macrofossils including Astelia, Cordyline, Ripogonum and Typha, as well as the oldest fossils known for Orchidaceae and Luzuriagaceae. This flora was dominated by Lauraceae with affinities to Cryptocarya and Litsea, but other families include Araliaceae, Cunoniaceae, Elaeocarpaceae, Euphorbiaceae sensu lato, Menispermaceae, Myrsinaceae, Myrtaceae, Onagraceae, Proteaceae and Sterculiaceae. Many ferns, conifers, and Nothofagus are from lineages with Gondwanan ancestors, whereas other taxa show links to Australia (e.g., Gyrostemonaceae), New Caledonia (e.g., Beauprea) and South America (e.g., Luzuriaga, Fuchsia). Many of these taxa are now extinct in New Zealand, and therefore indicate much wider biogeographic ranges for many families and genera in the past.  相似文献

The European Miocene records a wide diversity of hyaenid ecomorphotypes represented by multiple genera. Among these, Hyaenictis Gaudry, 1861, is one of the least known. This genus includes four species from the late Miocene and Pliocene of the Old World, but in Europe Hyaenictis is only represented by two species, recorded by scarce and fragmentary remains: Hyaenictis graeca Gaudry, 1861, from Pikermi (MN12; Greece) and Hyaenictis almerai Villalta Comella and Crusafont Pairó, 1948, from Sant Miquel de Toudell (MN10; Vallès-Penedès Basin, NE Iberia). Here, we describe a new skull of Hyaenictis aff. almerai from the Vallès-Penedès site of Ronda Oest Sabadell Sector D (MN10), representing the most complete European specimen of the genus. In the presence of m2 and virtual lack of m1 metaconid, the described cranium more closely resembles Hyaenictis rather than any other medium- to large-sized European hyaenid. However, the new skull does not fit well with previously known Hyaenictis species, more closely resembling the bone-cracking Adcrocuta Kretzoi, 1938, in the development of premolar accessory cuspids and the possession of relatively broad cheek teeth. These and other features (strong mandibular muscular insertions and enamel microstructure) denote more durophagous adaptations than previously documented in Hyaenictis (considered a cursorial/dog-like hyaena), and favor the inclusion of H. aff. almerai in the transitional bone-cracking hyaenid ecomorphotype.  相似文献
