Asset Overview
Huge thanks to Scan The World ( https://www.myminifactory.com/scantheworld ) who sent me to Brussels on a scanning trip: without them, this 3D model would not exist.
Museum of Natural Sciences, Brussels, Belgium.
Dimetrodon lived a little bit less than 300 million years ago (-2999 000 to -275 000 000), before the dinosaurs roamed the earth. It is considered to be a "mammalian reptile", a synapsid, not a dinosaur.
This is the scan of a cast, not a real fossil: since there was some artistic work involved, I can't allow the 3D model to be downloaded, sorry!
