Nice Triceratops sp. parietal section of a very big adult Triceratops. The frill is left in its natural condition, no restorations. The bone was just freed from matrix to expose the structure so typical for triceratops frill. Nice beautiful Hell Creek warm coloration.

Triceratops horridus

Late Cretaceous (67 - 66 mil y)

Hell Creek Formation, Montana, USA

295 mm - 11.6" (long)

Very good
