This rare Pterosaur tooth of Peteinosaurus was found in the upper triassic layers (Bull Canyon Formation, Dockum Group) of San Miguel County, New Mexico.
The first find of Pterosaur fossils are known from the triassic age. This fossil therefore belonged to one of the earliest Pterosaurs ever.
The tooth is complete, it measures about 4 mm.
Of course the plastic box is included.
Rarely offered unbroken fossil without any manipulations.
