Like pterosaurs, ichthyosaurs and plesiosaurs, Dimetrodon, while commonly mistaken for a dinosaur, isn't actually a dinosaur. In fact, unlike pterosaurs, ichthyosaurs and plesiosaurs, Dimetrodon isn't even a reptile, but instead belongs to a diverse group of animals that includes all modern day mammals. Seriously.
Before dinosaurs walked the Earth, there was a meat-loving beast called Dimetrodon, which researchers just determined had the first known serrated "steak knife" teeth.
This latest song from The Doubleclicks is about one of my favorite animals, Dimetrodon, a mammal-like reptile called a synapsid who lived during the Permian period, millions of years before dinosaurs evolved. Somehow, The Doubleclicks have figured out exactly why I love Dimetrodon.
This is Dimetrodon, the world's top predator about 270 million years ago. Living before the dawn of the dinosaurs, this striking creature was actual a distant ancestor of mammals like us. Now we've discovered the most complete Dimetrodon skeleton ever.
