Select two clades that constitute Eurypoda:

Which of the following is a characteristic NOT shared by stegosaurs and ankylosaurs?

First Ceratopsian dinosaur appeared in _____________ , migrated to _____________ and diversified in later Cretaceous.

The photo below is a picture of a basal ornithischian with feather.  Considering modern birds evolved from Theropod (a member of the other lineage, Saurischia,) this specimen brings up an important point in evolution of feather/dinosaur/birds.  What does this specimen tell you about their evolution?

The photo below is one of the best-preserved dinosaur fossils ever found.  Which statement(s) is/are applicable?  Select all that apply.

What are some of the problems that make it difficult to establish relationships in the clade pachycephalosauria?

What is shown on this picture (pointed by white arrows) ?

A pachycephalosaur’s tooth morphology (shown in the figure below) represents that of a typical primitive ornithischian tooth similar to that found in heterodontosaurids and thyreophorans. What does this tell us about its tooth function?

Stegosaurs are not found in Late Cretaceous rock record (thus, they may have gone extinct in early-middle Cretaceous.)  Based on what you learned in class, what is the possibility?  Provide at least three supporting evidence.

What does a big and commodious abdomen most likely mean for an ankylosaur?
