Suskityrannus hazelae NOT FOR RE-USE

An artist's rendering of how Suskityrannus hazelae may have looked.


Everyone’s heard of T-Rexes, the twenty-foot-tall monsters that roamed the Earth back in the Late Cretaceous Period. But you may not have heard of their miniature cousin. It’s a six foot tall dinosaur called Suskityrannus hazelae, and it gives us a clue about when and how T-Rexes got as big as they did. Sterling Nesbitt is the paleontologist who found the second and most complete fossil of this new dinosaur, and is the lead author on the paper in Nature Ecology & Evolution. However, it took him twenty years to put this discovery together. Phil Sansom asked him how.
