Hey everyone, this is for anything Sphenacodont--dimetrodon, or otherwise. Collections/pictures/discussions/whatever. This is the splinter thread off of the sphenacodont collections thread, so if anyone would like to bring over anything from the other thread, please feel free. I'm going to bring over some interesting posted info that covered different topics, and with links to interesting and useful info.
*some discussions covering other things and animals in relation to sphenacodonts is perfectly fine. For instance, spinosaurus, Permian topics, apex predators, or whatever. As long as it has some relation. Side-tracking is fine, just bring it back home before too long, please.
Here's a link to the previous thread. It would be greatly appreciated if you post pictures of any dimetrodon/sphenacodont fossil material you have:)
