According to Carr et al. 2005, Dryptosaurus is demarcated from 
Appalachiosaurus by the absence of a socket in the dorsal margin of the 
astragalus and the lack of the cranial process of the tibia.

Lianmugin Fm. is Shen and Mateer 1992. An outline of the Cretaceous system in 
northern Xinjiang, western China; pp.49-77 in Mateer and Chen (eds.), Aspects
