I’m definitely no expert on Dimetrodon or Triassic fossils, but Dimetrodon was one of my favorite critters as a kid and still think they’re pretty cool as a big kid. I found a nice claw that’s advertised as Dimetrodon and wanted to make sure it’s actually from that animal. The seller says this claw was found in Northern Texas in the Texas Red Beds formation. It’s 5/8” long.   What do you folks think?
