I’ve seen this chart floating around on my dash, and it occurred to me that I never posted the original version. So here is my and Jon's Dinosaur Classification Chart, in a hopefully Tumblr-palatable format.
Click here to see the moderately large version at DA.
This is a much simpler examination of dinosaur relationships than most of my watchers would probably find useful. Most of you will know that theropods are broken up into tetanurans and ceratosaurs, and that birds are nested within coelurosaurs, and that there are many internal divisions within sauropods and ornithiscians as well. But this chart is intended to be more of a quick, concise reference for laypeople, teachers, children, or whoever might have a passing interest in dinosaurs. My hope is that anyone who wants to quickly figure out what major group any given dinosaur falls into can glance at this chart and know immediately.
This was a collaboration between myself and Jon - I did the illustrations, and he did all of the layout and text. To see this chart in full resolution, please consider buying a poster in my Zazzle shop.
