Bachatsk Quarry (Pleistocene of Russian Federation)

Where: Siberia, Russian Federation (54.0° N, 86.0° E: paleocoordinates 54.1° N, 86.0° E)

When: Sagarlyk Formation, Early/Lower Pleistocene (2.6 - 0.8 Ma)

• In the Late Cenozoic an almost continuous sequence of Quaternary sediments, over 150 m thick, ranging from the beginning of the Early Pleistocene to the Holocene, was accumulated in this area.

Environment/lithology: terrestrial; coal and sandy claystone

• The Panthera mandible IGM-519 was found in the Bachatsk Quarry, in the section represented by sediments of 2 extremely diachronous and lithologically-different subaqueous formations. Very compact gray–green sandy clays of Sagarlyk Fm are overlain with a significant hiatus by the lacustrine–alluvial gray–blue plastic clays of the Kedrovka Fm. The subaerial deposits of the Sergeevo Fm separating these subaqueous sequences in the complete sections are missing in this outcrop.

Size class: macrofossils

Preservation: permineralized, replaced with other
