The Tyrannosaurus Rex: History's Greatest Immigrant?
IN THE YEAR 1909, the renowned fossil hunter, Barnum Brown, made one the most legendary fossil discoveries of all time, he unearthed the bones of the Tyrannosaurs rex! This discovery Introduce the world
Reconstruction of the T. rex type specimen (CM 9380) at the Carnegie Museum of Natural Historyto what is now not only the most popular dinosaur, but arguably the most iconic prehistoric creature known to man today. Just a few years ago, a shocking revelation was made by two geologists that has given us a deeper look at the the evolutionary history of the T-Rex.
Stephen Brusatt (PhD) and Thomas Carr (Phd) are two palaeontologists who have devoted their lives to the Earth Sciences and one of them, Carr, completed his PhD here at the University of Toronto! The two previously studied the evo-lutionary growth of tyrannosaurus in a paper published in 2010, but, …show more content…
Firstly, the analysis showed that the body of the tyrannosaurus that we’ve come to recognize today actually came around relatively slowly, as opposed the rapid devel-opment that some had previ-ously thought. Secondly, there was little difference between species from Northern North America to Southern North America. This tells us that Tyrannosauruses travelled all over North America saying quote: “our topology suggests that they were dynamic organisms capable of recurrent faunal interchange (Bursett and Carr, 2016).” Furthermore, these dynamic tendencies lead us to believe that tyrann-osauruses may have been immi-grants! The analysis shows that the same species of tyran-nosaurus alternates frequently between Asia and North Ame-rica. We don’t know where the species started, so it’s possible they could have originated in Asia, making them an invasive
