Holotype

AMNH 6523, incomplete skull and maxilla, first cervical vertebrae and some dermal scutes. Represented by abudant material including an excellent skull and postcranial skeleton of a juvenile. The premaxilla is not covered by dermal ossifications, and the large oval nostril faces rostrally and is divided by a horizontal septum.

At least in juveniles, the nasal area has a laterally situated third opening that leads into a premaxillarly sinus. The beak is slightly wider than the distance between the caudalmost maxillary teeth. A joint expedition of Hayashibara and the Mongol science academy found a mass of 22 young individuals of 2 m in body length of Pinacosaurus in the Gobi Desert.

This was the second finding of a Pinacosaurus mass since the CCDP found 12 individuals of Pinacosaurus in \\\\\\\'88 and \\\\\\\'90.
