Can everyone see this figure? This is Tarjadia, an early pseudosuchian related to Erpetosuchus and Ornithosuchus. White is known elements, olive is missing material.

Cool study, thanks for sharing!  I find it interesting how few teeth Tarjadia had in its upper jaw.

Apparently that's a feature common to erpetosuchids, but I have no idea what the functional significance of that might be. It's definitely odd!
