Various versions of Dimetrodon, with and without sails or humps, and with both mammalian and reptilian faces.
I'd say remove the cat nose on #4 but keep the whiskers and you have the most accurate one.
Instead of being a finback (Bakkerian) Dimetrodon has turned into a noodleback! This is a really nice and simple diagram of a more modern look for Dimetrodon. Keep up the great work
The second one at the under is probably the most accurate one
I still love number 1 of Dimetrodon.
Good work. The one I find most feasible is number 4.
Very cool! Really love that adorable dog-ish face!
Even though they are mammal like reptiles I still enjoy them with the more reptilian face. what about you?
