Tyrannosauridaes are a Family of Dinosaurs in the Suborder of Theropoda. These giant carnivores first appeared in Asia back in the Jurassic period and then later migrated to Europe and North America, which drove out other Species of Carnivores. One of the oldest known relatives to the Tyrannosaurids were the Proceratosauridaes, small Dromaeosauridae-like Dinosaurs, but don't get confused with Tyrannosaurs and Proceratosaurs, they're two different Families. By the Cretaceous many different species appeared including but not limited to Daspletosaurus, Albertosaurus, Gorgosaurus, Tarbosaurus, Alioramus and most famously Tyrannousaurus. Many characteristics of these Dinosaur included large, strong and thick teeth, forward facing eyes, wide skulls, short arms with two fingers and some light feathers on the neck, shoulder and back (still up to debate on were the feathers were on a Tyrannosauridae). They have a unique predator-prey relationship with Ceratopsidaes with a species of Ceratopsidae in the same general area of a Tyrannosauridae Species all over the Northern Hemisphere. These Dinosaurs are truly fascinating and though most of them are quite similar they are all unique at the same time.
