Prehistoric T Rex Dinosaur Coloring Page

The first T. rex skeleton was discovered in 1902 by Barnum Brown, a paleontologist at AMNH. After working for the AMNH in Wyoming, USA, for several years, Barnum Brown led an expedition to the Hell Creek Formation in southeastern Montana in the late 1890s and discovered and extracted the first remnants of Tyrannosaurus rex there in 1902.
