The Tyrannosaurus rex (T. rex) has long been a creature of interest for the human race. Some Native Americans thought this dinosaur's fossils were from a legendary creature and would burn the bones in hopes their wishes would be granted. It was not until the 20th century that scientists discovered T. rex and began officially studying it.
Paleontologist Barnum Brown found the first partial specimen of a T. rex in 1900 in eastern Wyoming. Two years later, Brown found a much more complete skeleton in the Hell Creek Formation in Montana. Brown's discoveries drew other paleontologists to T. rex, and soon the study of this new species exploded.
Through the years, over 50 T. rex skeletons have been found around the world. As paleontologists studied these specimens, new theories were developed and old theories discarded. For example, as late as the 1970s, it was thought T. rex walked upright with its tail on the ground. Scientists eventually realized this would have been impossible for a living animal to achieve, and introduced T. rex's more horizontal posture.
There are plenty more T. rex secrets paleontologists have yet to discover. To think, each new fossil dig could hold the answers we've all been waiting for!.
