Cosgriffius

Cosgriffius is an extinct genus of trematosaurian temnospondyl within the family Trematosauridae.^[1][2][3] It was described in 1993 by Samuel P. Welles based on a single partial skull from the well-known Meteor Crater Quarry (Early Triassic Moenkopi Formation) in Arizona that also produced more abundant remains of the capitosaur Wellesaurus peabodyi.^[4] The skull was long and slender, features typically associated with the trematosaurid subfamily Lonchorhynchinae. This is the only trematosaurid known from western North America.
