Analysis Of The Tyrannosaurus Rex

Improved Essays
Dinosaurs, these wondrous creatures have ensnared the imagination of children and paleontologist alike for several generations. The possible discoveries of dinosaur fossils during the ancient Roman, Greek and Chinese civilizations were what gave rise to legends of griffins, dragons and other monstrous lore. With every new discovery there have been great leaps made in understanding the dinosaurs. Yet there is one dinosaur in particular that has continued to captivate the imagination of children and paleontologist and that is the fierce Tyrannosaurus Rex. The purpose of the paper is to focus on the Tyrannosaurus Rex and to discuss three different topics about the monstrous creature that not many people know about them. The first topic will focus …show more content…
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In 2015 Carr was able to study Jane and spoke about his team’s unpublished study at a convention in Dallas, Tx.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

    In the article for this week, we explore the Tytannosaurus rex, or the T. Rex. If we were to translate this, it means tyrant lizard king. This definition gives off very powerful image of the dinosaur. Paleobiologists have tried to study the T. Rex fossils to put their lifestyle and habits into perspective for humans. People continue to study these dinosaurs to discover new things that other scientists have over looked in the past.…

    Throughout the story the sound of thunder is thought to have different kinds of meanings. Bradbury utilizes the title to describe the different and most important scenarios that occur over the length of the story. The title of the story is exceptionally effective in depicting the major events that had occurred throughout the story. The first sound of thunder was the footsteps of a dinosaur which was the beast Eckles and the hunters were looking for to kill. This is reviled as Bradbury states “Out of the mist came a Tyrannosaurus Rex” (280).…

    "(Pg. 204, 206). We are able to see from the conversation of the paleontologist Doctor Alan Grant and the two children, Tim and Lex, that because Jurassic Park is filled with animals that belong in a different era, it is incredibly hard for humans to survive them. Also from the quote, you can see how the people alone on this island must use teamwork if they want to make it off the island alive. The dinosaurs have never dealt with the humans and humans never with the dinosaurs.…

    His presence is quickly detected by a swarm of Procompsognathus, and Hammond, unable to flee, is swiftly killed and devoured by the hungry dinosaurs, sealing his fate once and for all. Grant yet again makes another startling discovery concerning the dinosaurs of Jurassic Park: since many of the dinosaurs were cloned utilizing the DNA of sex-changing frogs to fill in the missing gaps in the DNA sequence, many of the dinosaurs on the island changed sex from male to female to compensate for living in a same-sex environment, which could explain the presence of the Velociraptor eggshells that Grant, Lex, and Tim stumbled upon earlier in the jungles of Isla Nublar. In the end, Gennaro has requested that the Costa Rican Air Force destroy the island and all of its cloned prehistoric fauna, as he claims that the island is too hazardous of an asset to…
