Late Pleistocene microtine rodents from Snake Creek Burial Cave, White Pine County, Nevada, 1998,
Deprecated: Function get_magic_quotes_gpc() is deprecated in /home/isthin5/public_html/addon-domains/ on line 943
Bell Cj, Mead Ji,
A total of 395 microtine rodent specimens recovered from Snake Creek Burial Cave (SCBC) are referred to Microtus SP. and Lemmiscus curtatus. Radiocarbon and Uranium series dates indicate an ae for these fossils of between 9460 160) yr. B.P. and 15,1000 700 yr, B.P. The sample of lower first molars of Lemmiscus includes 4-, 5-, and B-closed triangle morphotypes. Earlier reports of the 4-closed triangle morphotype are from Irvingtonian deposits in Colorado, Nevada, and New Mexico and from early Rancholabrean deposits in Washington. The morphotype is not known in living populations of Lemmiscus. SCBC specimens constitute the youngest record of the 4-closed triangle morphotype and are the only-specimens reported item the late Rancholabrean. Thc time of disappearance of Lemmiscus with this molar morphology is unknown, but populations with this morphotype possibly became extinct at or near the end of the Pleistocene

A Pleistocene Tapir and Associated Mammals from the Southwestern Ozark Highland, 2002,

A mud deposit in Sassafras Cave near Stilwell, Oklahoma, produced a small assemblage of fossil vertebrates including an unidentified salamander and the mammals Myotis sp., Lasionycteris noctivagans, Pipistrellus subflavus, Tamias striatus, Peromyscus sp., Reithrodontomys sp., Microtus sp., and Tapirus veroensis. The fossiliferous mud deposit is a stream terrace containing abundant red clay accumulated behind roof fall and breakdown boulders that temporarily dammed the main stream-passage of the cave. The tapir fossils indicate a late Rancholabrean (late Pleistocene) age for the deposit. This is the first report of a tapir from the Oklahoma Ozark Highland and only the second report of Pleistocene megafauna from a cave in eastern Oklahoma. The tapir is represented by a partial skeleton with some of the distal leg bones articulated in life position in the deposit. The animal probably died while it was standing or laying in the mud, possibly after falling into the cave or walking in through an entrance that had a different configuration in the Pleistocene than the present sinkhole entrance

At least 132 specimens belonging to no less than 21 species of small terrestrial mammals from the Boreal were identi- fied within the finds from the Early Holocene sediments from Mala Triglavca (the Kras Plateau, SW Slovenia), namely Crocidura suaveolens, Sorex alpinus / araneus, S. minutus, Talpa cf. europaea, Barbastella barbastellus, Sciurus vulgaris, Cricetulus migratorius, Arvicola terrestris, Microtus agrestis / arvalis, M. subterraneus / liectensteini, Chionomys nivalis, Myodes glareolus, Dinaromys bogdanovi, Glis glis, Muscardinus avellanarius and Apodemus flaavicollis / sylvaticus / agrarius / uralensis. This small mammal assemblage indicates that their habitat was presumably a mosaic of a mixed, predominantly deciduous forest, dotted with small meadows and some rocky substrate. A comparison of allochronous microfaunas from the Kras Plateau indicated a rapid faunistic change in the last 5,000 years.

Eight caves and one filled cave passage containing mammal bone remains and terrestrial molluscs were discovered in the Severo-Muisky, Delyun-Uransky and Aglan-Yan Ranges in the Kelyana, Pravyi and Sredny Mamakan river basins of the Stanovoj Upland. Nineteen species of mammals were identified among collected bones: Ochotona hyperborea, Lepus timidus, Myodes rufocanus, Myodes rutilus, Microtus cf. gregalis, Microtus cf. oeconomus, Microtus arvalis, Myopus schisticolor, Tamias sibiricus, Pteromys volans, Martes zibellina, Plecotus auritus, Murina hilgendorfi, Amblyotus nilssoni, Myotis brandti, Myotis petax, Myotis bombinus, Rangifer tarandus and Cervus elaphus. Four taxons were determined to a genus (Lepus, Myodes, Microtus and Alticola), one to a family (Mustelidae), three to an order (Insectivora, Artiodactyla, Carnivora) and one to a class (Aves); five species of terrestrial molluscs were also found: Vallonia tenuilabris, Bradybaena schrencki, Nesovitrea hammonis, Discus ruderatus, Euconulus fulvus. The layers containing mammal remains are of Holocene Age based on preservation state of bones. The site with molluscs’ shells within the filled cave passage on the watershed near the Prokhodnoi brook could be formed in Holocene, as well as in Pleistocene. All identified species are typical representatives of fauna of the mountain taiga landscapes in the south of Eastern Siberia. The described locations of fauna remains are the only known, within the studied area.
