Info Blurb:
Gorgosaurus was a relatively small tyrannosaur of approximately 25 feet ( 7.62m) that lived over 70 million years ago in what is now western North America and Canada. It would have shared it’s habitat with a wide variety of herbivores but the most common were the Hadrosaurs. These included Brachylophosaurus , Gryposaurus and the Corythosaurs illustrated above.
The sycamore trees are members of the family Platanaceae and this group of modern trees would have been a common sight in the Late Cretaceous, along with ferns, horsetails and various mosses. There is one obvious exclusion from the mega flora of what would become the Great Plains and Rocky Mountains of North American however. There were no grasses in the Big Sky Country; these would not evolve for many millions of years--------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------
