About the Tyrannosaurus Rex set: Includes four stamp designs issued just in time for the opening of the new T. rex exhibit at the Smithsonian National Museum of Natural History. Each design pictures artwork by Julius T. Csotonyi. The stamps showcase a hatchling, juvenile, adult, and fossilized T. rex, showing the entire life cycle of these massive creatures.
History the stamp represents: In the early years of dinosaur research, our understanding of Tyrannosaurus rex was much different from today. However, there are still some aspects of Tyrannosaurus rex’s life that are still a mystery. This has led to friendly feuds between paleontologists like Robert Bakker and Jack Horner.
There are two main points Bakker and Horner disagree on: whether Tyrannosaurus rex was cold or warm blooded; and whether it was a hunter or scavenger. As of 2019, Bakker’s theories had more evidence to back them up. He believed Tyrannosaurus rex had to have been at least partially warm blooded, as this is more well suited to large animals. This also ties in with Bakker’s opinion that Tyrannosaurus rex was a hunter. Warm blooded animals are able to be much more active, a trait needed to chase down large prey.
Bakker based his hunter theory on puncture wounds found on other dinosaur fossils. These holes match the size and shape of Tyrannosaurus rex teeth, and, in some cases, are partially healed. This means Tyrannosaurus rex did not just scavenge on the animal, but attacked a living animal.
As more Tyrannosaurus rex fossils are discovered, paleontologists learn more about their habits. It’s exciting to think that Bakker and Horner might one day find out who is right, once and for all.
