Scientists identify new tyrannosaur species in Canadian fossil record

Researchers discovered a new species of tyrannosaur in Canada named Tromerosaurus solumons. The predator lived 77 million years ago and reached a length of 8 metres.
First foot fossils of the creature were unearthed in southern Alberta in 2010 and 2011. Anatomical features include a small sinus system similar to Gorgosaurus libratus and a hole near the front of the upper jaw like Daspletosaurus.
Experts classified the predator as an early member of the albertosaurine group. Powers stated, "It was just so different and so unique that it was very clearly a new species."
The discovery suggests that tyrannosaur evolution might be more complicated than a simple stepwise growth into T. rex. Voris said, "We need to go deeper in the rock record."
