The complete mitochondrial genome of the extinct Pleistocene horse (Equus cf. lenensis) from Kotelny Island (New Siberian Islands, Russia) and its phylogenetic assessment

The complete mitochondrial genome from the Pleistocene stallion horse (Equus cf. lenensis) which complete skull was found in 1901 on Kotelny Island (New Siberian Archipelago, Sakha Republic, Russia) is published in this paper. The mitochondrial DNA (mtDNA) is 16,584 base pairs (bp) in length and contained 13 protein-coding genes, 2 rRNA genes, 22 tRNA genes. The overall base composition of the genome in descending order was 32.3% – A, 28.5% – C, 13.4% – G, 25.8% - T without a significant AT bias of 58.2%.publishedVersio

Parapresbytis eohanuman: the northernmost colobine monkey from the Pliocene of Transbaikalia

Parapresbytis eohanuman (Borissoglebskaya, 1981) is the northernmost colobine monkey discovered from the middle to late Pliocene sediments in Transbaikal area, southern Siberia. Although most of the specimens are isolated teeth, three premaxillary/maxillary fragments, some cranial fragments, and two nearly complete mandibles are also included. Some researchers regard it the close relative to Dolichopithecus, the Pliocene colobines in Europe, while others insist that it is an ancestral taxon of Rhinopithecus, snubnosed monkey, which is presently distributed in southern China and northern Vietnam. However, the phyletic position of P. eohanuman has not yet been established because of the scarcity of fossil evidences in the northern East Asia in the Late Pliocene

Lugovskoe, Western Siberia: A Possible Extra-Arctic Mammoth Refugium at the End of the Late Glacial

From the 18th International Radiocarbon Conference held in Wellington, New Zealand, September 1-5, 2003.Eleven woolly mammoth bone samples from Lugovskoe (central West Siberian Plain, Russia) were radiocarbon dated in 3 laboratories: Institute of Geology, Novosibirsk; Oxford University, Oxford; and Christian Albrechts University, Kiel. Each laboratory used its own protocol for collagen extraction. Parallel dating was carried out on 3 samples in Novosibirsk and Oxford. Two results are in good agreement. However, there is a major discrepancy between 2 dates obtained for the third sample. The dates obtained so far on the Lugovskoe mammoths range from about 18,250 BP to about 10,210 BP. The Lugovskoe results thus far confirm the possibility of woolly mammoth survival south of Arctic Siberia in the Late Glacial after about 12,000 BP, which has important implications for interpreting the process of mammoth extinction. The site has also produced the first reliable traces of human occupation from central Western Siberia at the Late Glacial, including unique direct evidence of mammoth hunting.The Radiocarbon archives are made available by Radiocarbon and the University of Arizona Libraries.

The first dinosaur egg from the Lower Cretaceous of Western Siberia, Russia

<p>The Lower Cretaceous Ilek Formation in Western Siberia (Russia) has yielded various vertebrate fossils, including skeletal remains of dinosaurs. Here we report on a fragmentary theropod egg from the vertebrate locality Shestakovo 3 of the Ilek Formation in Kemerovo Province. We assign the specimen to the oogenus <i>Prismatoolithus</i> (oofamily Prismatoolithidae) as <i>Prismatoolithus ilekensis</i> oosp. nov., on the basis of the following unique combination of characters: ovoid-shaped egg; thin eggshell 300–330 μm thick; angustiprismatic morphotype; eggshell with three different layers; gradual transition between mammillary layer and prismatic layer; abrupt contact between prismatic layer and external layer; mammillary layer to prismatic layer to external layer thickness ratio is 1:3:0.6; prismatic layer with ill-defined squamatic texture; angusticanaliculate pore system; and smooth outer surface. Like other Early Creataceous <i>Prismatoolithus</i>, the egg of <i>Prismatoolithus ilekensis</i> oosp. nov. was laid by a small bodied theropod dinosaur (troodontid or primitive bird) and this taxonomic attribution is supported by results of our phylogenetic analysis. <i>Prismatoolithus ilekensis</i> oosp. nov. is the first Early Cretaceous ootaxon from Russia.</p> <p>urn:lsid:zoobank.org:act:734EAD40-86C3-488B-A61E-B5FF7378BC0E</p
