Khunnuchelys

Description

Khunnuchelys was a genus of trionychine turtle from the Late Cretaceous of Asia. Three species are known, K. erinhotensis, the type species, K. kizylkumensis, and K. lophorhothon. K. erinhotensis lived in China from the late Turonian until the middle Campanian. K. kizylkumensis existed during the late Turonian of Uzbekistan. The third species, described in 2013 by Danilov et al., persisted from the early to middle Campanian of Kazakhstan.
