Luperosuchus -1(Skull)

Figure 1. Luperosuchus restored based on Romer 1971. Above: original drawing by Romer. Below tracing based on photo in Romer 1971, specimen PULR 04. Extension of the qj and a deeper max gives it more of a erythrosuchid look. At right is referred specimen PULR 057. Although related, the referred specimen strikes me as generically different with the low placement of the naris and large postorbital. Analysis on PULR 057 has not been done.(Text copied from source caption.).

Luperosuchus is a genus of rauichid crurotarsan, and lived in the mid-Triassic (Anisian stage). The type and only species is L. fractus.[1][2][3][4]
