Robert Bakker and his team found a new dimetrodon specimen complete with fangs!

Nicknamed "Wet Willi," the skull and fossils belong to Dimetrodon giganhomogenes. This reptile, with its iconic sail-shaped back, is often mistakenly identified as a dinosaur, and is even included in packages of toy dinosaurs…

In life, "Willi" was the dominant predator of his world. He would have been 11 feet long with a four-foot vertical fin running the length of his body. The purpose of the prominent fin that defines this species has been debated since it was first discovered by paleontologist Edward Cope in Texas in 1878.
