Two new mammal localities have been discovered in the Lower Cretaceous
Ilek Formation of West Siberia, Russia, during a field work in 2014.
The Smolenskii Yar locality in the Chebula District of Kemerovo
Province produced an upper molariform tooth (M2) of a Gobiconodontidae
indet. The Ust’-Kolba locality in the Tisul’ District of Kemerovo
Province yielded a lower molar (m2) of the zhangheotherian Kiyatherium
sp. These are the ninth and tenth Mesozoic mammal localities for
Russia. The Kiyatherium-bearing vertebrate assemblage from the
Shestakovo 3 and Ust'-Kolba localities is likely to be the youngest
within the Ilek Formation, reflecting the time after the extinction of
the Tritylodontidae.
