Stegoceras validum + Striatornata sp.

Stegoceras validum, a 2m long pachycephalosaur, looks even more diminutive next to Striatornata plants. Striatornata sanantoniensis is known from fossils further south alongside southern species of Steogceras, but similar species may have existed in the Dinosaur Park Formation with S. validum. Striatornata bleonged to the Musaceae, a group of plants including ginger and bananas. It appearance here is based on the later Spirematospermum (which could grow up to 3m tall) but with shorter, stouter seed pods, which look especially delicious to the little pachycephalosaur.
