Encyclopedia
Jushatyria is an extinct genus
of rauisuchid
. Fossil
s have been found in the district of Kumertau
near the Ural Mountains
in European Russia
that date back to the Ladinian
stage of the Middle Triassic
. Additional material has been described from a locality on the banks of the Berdyanka River that was previously assigned to a rauisuchid-like archosaur. However, this material differed from the original specimens because it lacked slit-like antorbital openings accomopanying the antorbital fossa
. Thus all material currently referred to Jushatyria most likely does not represent a single taxon.

Antorbital fenestra
An antorbital fenestra is an opening in the skull, in front of the eye sockets. This skull formation first appeared in archosaurs during the Triassic Period. Living birds today possess antorbital fenestrae, but the feature has been lost in modern crocodilians...
