If you couldn’t tell from the Pterosaur posts that have been appearing lately, sometimes some non dinosaur things end up ruling everything around me as well. Heres an awesome Dimetrodon specimen from my trip to the American Museum of Natural History last year. Here’s a bit of info from a post I made on my “Paleogram” (@Paleontology on Instagram) last week.
"This is Dimetrodon and you have a lot more in common with this animal than you think! While most people are quick to label these guys as dinosaurs or reptiles they are actually more closely related to mammals than anything else. Dimetrodon is a member of the synapsids, sometimes called the "mammal like reptiles" and went extinct 40 million years before the first dinosaurs appeared. A small opening (synapse) in the back of Dimetrodon’s skull is found in humans as well as mammalian ancestors in between.
Evolution, u crazy!”
