Young Tyrannosaur and other Tyrannosaurs

Young Tyrannosaur

This is a drawing of a young Tyrannosaur.  She is around 6 years old.  That makes her as big as a large horse.   There is evidence that it took a T. rex about 18 years to become an adult.  But they cotinued to grow after they reached sexual maturity.  The biggest were probably around 30 years old or so when they died.  There were several types or species of Tyrannosaurs.  The Tyrannosaurs include Daspletosaurus, Teratophoneus, Bistahieversor, Tarbosaurus, Nanuqsaurus, Zhechengtyrannus, and Tyrannosaurus.   Albertosaurus and Gorgosaurus are also closely related.  There was also Yutyrannus, Lythronax, and Moros intrepidus.  Some of these were small early Tyrannosaurs.  Some were almost as big as the King. . . Tyrannosaurus rex. 

(The above new drawing is found in printable form under the All Printable buttons or under the Paleontology Button.  The older drawings are at the bottom of the correct list. I am added older drawings below of some of these Tyrannosaurs that I mentioned.  Older drawings in printable form are not at the bottom of the correct list.  They are located further up the lits.
