Your Dinosaurs Are Wrong

This time, probably the second-most-popular ceratopsid, Styracosaurus--and by extension Rubeosaurus. Hope you're ready to learn about the environmental and social forces that shaped this giant pig-antellope-bird. ...and also what a parietal spike is.

Turns out our Stegosaurus was wrong, too. In the first of our new side-series for YDAW, we explain how!

This is one of the less accurate toys we've gotten. It would be difficult to restore a young Apatosaurus _louisae_ further from the truth.

We happened to go to the Field Museum of Natural History in Chicago, and of course Steven had things to say about some of the displays. The museum was kind enough to let us film comments about their Brachiosaurus, "Apatosaurus," Patagotitan, some exciting Antarctic dinosaurs, and of course Tyrannosaurus. Mounted skeletons have advantages over illustrations or models, but they're no more immune to ongoing science.

Part 1 of 2. Why is it such a big deal that Theropods might be more closely related to Ornithischians than either is to Sauropods? A (very) brief history of high-level dinosaur phylogenetics.
