This is a colored-pencil portrait of the tyrannosaurid Thanatotheristes degrootorum, the fossil remains of which were uncovered from the Foremost Formation in Alberta, Canada. It would have hunted other dinosaurs in the subtropical forests and wetlands of that region between 78 and 77 million years ago, and it seems to have been most closely related to another medium-sized tyrannosaurid called Daspletosaurus.
