In the book the description given of the T. Rex is that of a giant slow creature who’s skull is reinforced and is perfect for crushing and dismembering the bodies of other large dinosaurs deceased dinosaurs such a triceratops. The problem with Horner’s books is that he never provided any evidence or tested his theory on the Tyrannosaurus Rex. In 2008, Horner’s claims about the anatomy of a Tyrannosaurus Rex were tested by Holts, Jr an expert in tyrannosaur rex. Based on biomechanical studies and the limb proportions that have been retrieved from all the found fossils it is revealed that the Tyrannosaurus Rex was quick enough to catch run away prey. The reinforced skull that Horner stated was used to crush the bodies of deceased dinosaurs was probably used in subduing prey that struggled to get free from powerful dinosaur and its shattering powerful jaws. Without being able to see the powerful Tyrannosarus Rex out in its natural habitat to truly debunk the claims of it being only a predator or a scavenger comes the conclusion that it was possibly both. With its large nostrils it was possibly easier for it to sniff out fresh blood of a recent kill of another smaller predator for example that of a velociraptor; and it might have used its size to intimidate the other away from the fresh kill and take that …show more content…
In 2015 Carr was able to study Jane and spoke about his team’s unpublished study at a convention in Dallas, Tx. While at the convention he talked about how Jane showed to be much more similar to a Tyranossarus Rext than the first skull that was discovered in 1942. Apparently the features are exactly what would be predicted as necessary to make the change from juvenile to adult (Geggel, 2015). In 2003 Dr. Gregory Erickson was able to take a sample of Jane’s fibula and determine she died roughly near the age of 12. By analyzing the rings of growth in the bone paleontologist can determine the ages of growth spurts, Jane was going through one. Tyrannosaurs attained maturity around the age of 20and lived until their 30s; making Jane a juvenile. In 2005, Erickson demonstrated how the species grew by slicing through the bones of an adult tyronnaosaurs in order to analyze it. Erickson states how deep within her bones Jane’s real identity has emerged, had she grown to adult hood she would have fit right in while being a Tyranossarus Rex (Riley). Some interesting facts about Jane are how her arms are proportionately bigger and with more open shoulder joints. Like a puppy, Jane would have grown into her overly large proportioned feet. Despite all the information that has surfaced about Jane and how she is a juvenile there are still many paleontologists that do not agree with the
