(Late Cretaceous, Harding County, SD)

Apparently our adult Edmontosaurus survived an attack from a theropod, which left deep gouges in the right dentary and shallower gouges in the left dentary. The Edmontosaur may have pulled away from its attacker, causing the deep wounds. Close examination suggests that the wounds may have begun to heal, leading to the possibility that it survived the attack for awhile, only to succumb to infection and die a short while later.

All four tooth batteries are completely intact. Exposure of the lingual surfaces clearly show the vertical stacking of the teeth, of which this animal possessed nearly 2,000. Wear surfaces are perfectly preserved. Hadrosaurian predentaries are exceedingly rare. Not only was this example intact, but was nearly in its proper position relative to the skull and dentary. Despite its injuries, or perhaps because of them, this is one of the finest Edmontosaur skulls in existence!
