Abstract

The mandible of a gigantic bear from the terminal Miocene of the Kosyakino quarry in the Stavropol Territory of Russia is described. The presence of a premasseteric fossa of the mandible and characteristic features in the structure of the lower cheek teeth (P4 with posterior cingulid cusp and without medial ridge, M1 with elongated paraconid, large metaconid, double entoconid and developed mesoconid, and M1–M2 without cingulids) allow to attribute the studied specimen to the genus Huracan and to erect a new species, H. borissiaki.
