New Triassic Dino from Brazil

[Troodon]

A very well preserved herrerasaurid dinosaur, Gnathovorax cabreirai is described in the attached paper.  For us collectors it gives us clues around Carnian age teeth.  Unfortunately most of the teeth available to collectors are Norian or earlier in age.

Unfortunately the paper does not do a great job describing the teeth, here is what we have:

"All tooth crowns are blade like, caudally curved and labiolingually compressed. The premaxillay and dentary teeth lack serrations in their mesial margins. However, in the distal margin there are small serrations that form a right angle with the main axis of the tooth. In the maxillary teeth the serration occur in both margins."
