The Tyrannosauridae originated in Asia more than 100 million years ago. This family of theropod dinosaurs is comprised of about 9 genera including Tyrannosaurus. Tyrannosaurus rex first appeared in North America about 67 million years ago (MYA). The landscape they inhabited looked completely different from the western interior plains of today. At that time South Dakota closely resembled a richly diverse subtropical environment. T. rex territory included palm, ginkgo, and redwood trees, and many types of ferns, but was nearly devoid of grasses.
This brightly colored dinosaur makes an excellent child's toy. There are several Vinyl Models available in the Favorite Collection line of soft bodied toys. Mr. Kazunari Araki, a famous Japanese sculptor, supervised the the production of this line of Favorite Collection models.
