†Pamizinsaurus tlayuaensis Reynoso, 1997
|
Pamizinisaurus is a genus of sphenodontian reptile known from Lower Cretaceous (Albian) Tlayúa Formation of Mexico. A crushed skeleton of a juvenile reptile was found in Tlayua Quarry, in central Mexico.[1] It was named Pamizinsaurus tlayuaensis by Reynoso in 1997, after the name of the quarry of which it was found. Its skull length is 16 millimetres (0.63 in).[2] The fossil was covered in small round osteoderms that could have protected it from predators.[1]
Relatives
Reynoso (1997) argued that Pamizinsaurus was a genus of the subfamily Sphenodontinae; grouping it with the modern Sphenodon (better known as the Tuatara), Zapatadon, Cynosphenodon, Homoeosaurus, Sapheosaurus, and Ankylosphenodon.[1]
