During an expedition to the Krasnoyarsk Territory, scientists from Tomsk State University and St. Petersburg State University (TSU and SPBU), discovered the remains of a previously unknown mammal, the baidabatyr.
It is classified among multituberculates, one of the ancient taxa of mammals of the Middle Jurassic. The name derives from the structure of its teeth.
