Gorgosaurus and Daspleteosaurus were both tyrannosaurs that lived in the same environment. THey were believed to eat different types of prey, but to my mind they’d probably eat anything they could get.
This is my idea of a encounter between the two, a Daspleteosaurus confronting a piebald [because I could] Gorgosaurus who had taken down a already injured and weakened Styracosaurus, not its usual kind of prey but it was a opportunity.
I plan to use this illustration in one of my work in progress books about theropods.
