Pamizinisaurus is a genus of sphenodontian reptile known from Lower Cretaceous (Albian) Tlayúa Formation of Mexico. A crushed skeleon of a juvenile reptile was found in Tlayua Quarry, in central Mexico. 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). The fossil was covered in small round osteoderms that could have protected it from predators.
