Ostafrikasaurus Posted January 16, 2016 Share Posted January 16, 2016 I found this fossil of a piece of Dimetrodon spine on ebay from a presumably reputable site. Is the fossil genuine? And if it is, does it really belong to Dimetrodon? Link to comment Share on other sites More sharing options...
Troodon Posted January 16, 2016 Share Posted January 16, 2016 (edited) Looks like others I've seen but not sure of specific Synapsid it may be. Added the image from seller for others to take a quick look. Here is one in my collection Edited January 16, 2016 by Troodon Link to comment Share on other sites More sharing options...
Coelacanth Posted January 20, 2016 Share Posted January 20, 2016 Either Dimetrodon sp. or Ophiacodon sp. Link to comment Share on other sites More sharing options...
