Records of Bison priscus Bojanus (Artiodactyla, Bovidae) skeletons in Western Siberia

Abstract

skeletons or even their articulated fragments are rare. Occasionally, the remains represent postcranial skeletons (Shpansky, unpublished data). In the West Siberian Plain, only three relatively complete articulated bison skeletons have been discovered to date. These include records in the sites of Vladimirskaya mine (Tom River, Kemerovo Region), Grigorievka Village (Irtysh River, Pavlodar Region), and Krasniy Yar Village (Ob River, Tomsk Region; Fig. 1). The burial in the Vladimirskaya mine was described by P.M. Ryzhkov (1927). The skeleton was located in diagonally layered alluvial sands at a depth about 6 m and comprised 34 bones, including a skull fragment and both mandibular rami. The two other finds have not been published yet (apart from morphological analysis of * Corresponding author 1 Note that two different sites with the name "Krasniy Yar" are mentioned in this paper. To avoid confusion, here and further in the text, the exact location of the site is specified in brackets.

A Middle Pleistocene steppe bison find within the Dürnstein Castle (Wachau, Lower Austria)

“…The Western Siberian range is 74-90 mm for 75 cows, and 80-108 mm for 143 bulls. Means are around 79 mm for females and 93 for males (Shpansky et al, 2016). As a result the Krems-Kreuzbergstraße specimen (84.0 mm Bd) is close to the mean.…”

“…Martin (1987) observed a radius length range of 334-425 mm (N=28) from Rhine terraces, again below the Dürnstein specimen. Observations on Western Siberian Pleistocene populations report 343-431 mm for male individuals (N=49), and the range of 102 further specimens is 333-414 mm (Shpansky et al, 2016). The dimensions of the proximal and the distal ends of the radius of the Dürnstein bison underline its large size and sturdiness (Figs.…”

“…Finalmente, la hendidura articular de la ulna es amplia y presenta un ángulo obtuso de aproximadamente 135° (Olsen, 1960;McCuaig-Balkwill y Cumbaa, 1992;Barone, 1995;Pales y Garcia, 1981;France, 2009 Guthrie, 1966), además de que es parte del grupo de bisontes de origen eurasiático (McDonald, 1981). Los radios de B. priscus son largos y gráciles, pero con epífisis gruesas, lo que les da un aspecto de tener una cabeza amplia (Shpansky et al, 2016), en contraposición, el elemento UM 1346 no presenta una región epifisiaria notablemente expandida (Figura 6). En B. priscus la ulna se encuentra fuertemente anquilosada al radio (Prat et al, 2010;Shpansky et al, 2016), mientras que en UM 1346, se observan claramente la superficie de sinostosis radio-ulnar y la zona de inserción del ligamento interóseo proximal y no existe evidencia de anquilosis, lo que sugiere la presencia de un espacio interóseo proximal bien desarrollado.…”

Además, en B. priscus (Figura 7) el relieve lateral de inserción se presenta en un ángulo cercano a 90°, presenta una tuberosidad lateral muy grande, alta y ligeramente hendida, con un borde dorsal que se encuentra a la misma altura del proceso coronoide y en algunos ejemplares, incluso lo excede en altura (Prat et al, 2010…”

CHRONOLOGY OF THE MIS 3 MEGAFAUNA IN SOUTHEASTERN WEST SIBERIA AND THE POSSIBILITY OF LATE SURVIVAL OF THE KHOZARIAN STEPPE MAMMOTH (MAMMUTHUS TROGONTHERII CHOSARICUS)

“…The 14 C dating of mammalian fossils was conducted by both liquid scintillation counting (LSC; lab code SOAN) and accelerator mass spectrometry (AMS; lab codes UBA, GrA, and AA) (Tables 1-2). Methods of the pretreatment of bones are fully described in Kuzmin and Orlova (2004) for LSC; and in Zenin et al (2000), Shpansky et al (2016), and Kuzmin et al (2018) for AMS. We applied the quality criteria for bone collagen suggested by van Klinken (1999) and Brock et al (2012), with the determination of the collagen yield, C:N ratio, and stable isotopes (δ 13 C and δ 15 N) values whenever possible.…”
