An article published in the journal “Communications Biology” reports the identification of a new species of tyrannosauroid, the superfamily of carnivorous dinosaurs the famous T.rex belongs to. A team of researchers examined a very incomplete skeleton dating back to about 96 million years ago and named the species, which lived in today’s Utah, Moros intrepidus. It’s the oldest tyrannosauroid discovered so far in North America and this can help to understand the evolution of these dinosaurs in the larger forms that lived later.
