Paralligator gradilifrons

Reptilia - Paralligatoridae

Taxonomy
Paralligator gradilifrons was named by Konzhukova (1954). Its type specimen is PIN 554-1, a partial skull (Nearly complete skull, lacking palate), and it is a 3D body fossil. Its type locality is Shiregin Gashun (PIN coll. 554) [MPE], which is in a Cenomanian/Santonian terrestrial sandstone in the Baynshire Formation of Mongolia.

It was recombined as Shamosuchus gradilifrons by Efimov (1982), Efimov (1983), Storrs and Efimov (2000) and Turner (2015).

Synonyms

Its type locality is Nogon Tsav (PIN 3141) [SMPE/SMGE], which is in a Maastrichtian terrestrial siliciclastic in the Beds of Nogon Tsav Formation of Mongolia.
