Tyrannosaurus rex was one of the largest land carnivores of all time; the largest complete specimen ("Sue"),
measured 42 ft long, and was 13 ft tall at the hips.
Sue Hendrickson, amateur paleontologist, discovered the fossil skeleton in the Hell Creek Formation near Faith, South Dakota.
It has now been reassembled and is currently exhibited at the Field Museum of Natural History. A study of this specimen's fossilized
bones showed that "Sue" reached full size at age 19 and died at age 28, the longest any tyrannosaur is known to have lived.
The "Sue" specimen apparently died from a massive bite to the head, which could only have been inflicted by another tyrannosaur.
Kids love to color dinosaurs and imagine what they looked like millions of years ago. Dinosaur coloring pages are a great way to teach early earth history.
