Comparing Tyrannosaurus Rex and Raptor Essay

A dinosaur has an antorbital fenestra with an open hole hip socket. The definition differs from the term used informally because it helped understand how the dinosaur moved and how they were categorized as species. There are four general characteristics that dinosaurs have as a result of their synapomorphies which are permeated acetabulum, ball-shaped head on proximal femur, the Cnemial crest on the proximial tibia, and an ascending process on astragalus. These four dinosaur synapomorphies are related to vertical limb support.

Trex is a big dino but the babies are super small to a mother trex so the mom and dad take turns to watch the little baby rex's and the other trex would hunt and come back for its turn. when the baby is 1 year old the mom kicks it out of the nest and it lives the rest of its life alone until it finds a mate. T-rex means “tyrant lizard” in one bite T-rex could eat up to 500 pounds

The basilosaurus is a whale species that existed over 40 million years ago in the Paleogene period. These 90-feet-long whales swam in the warm, shallow tropical seas. This species is especially common in the state of Alabama, as that the continental coast line once existed in the modern black belt region. Similarly, the mosasaur was very common in Alabama. The mosasaur most closely relates to the snake or the lizard, with an average length of 60 feet. The mosasaur had the ability to unhinge its jaw when it ate, as well as having teeth in the back of its throat in order to prevent prey from climbing back out its mouth. The museum has one of the biggest collection of mosasaur remains.

The Stegosaurus is said to be twenty-six to thirty feet long and about nine feet tall! the stegosaurs weighed six thousand-eight hundred pounds, can you believe that? but it had a very small brain, about the size of a nut. they are herbivores, meaning they only eat low plants and crops. they have seventeen bone plates that grew out of its back! some think that their plates helped them look bigger maybe to scare off the meat eaters or maybe just to show off. they also have spikes on their tail, the stegosaurus tail is four feet long as their tail is also very flexible and they can use to protect themselves from large predators or scare those carnivores. Its name also means covered lizard, they could not walk very fast and some paleontologists believe that if that if they had blood veales running through their plates that its plates could change color, pretty interesting right?

The Tyrannosaurus rex has a bone-crushing force skull, massive and long legs, and a brain that has a strong sense of smell. These characteristics were beneficial to the T-rex. First, the jaw of the T-rex was able to crush their prey's bones and drag the meat further which is also known as puncture and pull strategy. Next, the T-rex legs were massive and long especially in the juvenile stage because it had the strength of an adult legs which they were able to fast walk. Lastly, the T-rex had a strong sense of smell and binocular vision which can easily capture their prey. On the other hand, their arms were shortened relative to the size of T-rex body. There was no evidence that the T-rex used their arms for predation or scavenging.

Velociraptor was a mid-sized dromaeosaurid, with adults measuring up to 2.07 m (6.8 ft) long, 0.5 m (1.6 ft) high at the hip, and weighing up to 15 kg (33 lb).[3] The skull, which grew up to 25 cm (10 in) long, was uniquely up-curved, concave on the upper surface and convex on the lower. The jaws were lined with 26–28 widely spaced teeth on each side, each more strongly serrated on the back edge than the front.[1][4]

Tyrannosaurs Rex, better known as the T-Rex, which means Tyrant lizard king lived during the late Cretaceous period, about 85 million to 65 million years ago. They were 40 feet long and 20 feet tall and weighed up to 7.5 tons. They were strictly carnivores and used their very sharp teeth to eat other dinosaurs. Fossils were discovered in Western North America and the skull of a T- Rex alone measured up to 1.5m(5ft) long. The also have the record of having the largest tooth of any carnivorous dinosaur found to this day, which is around 30cm (12in) long. When the T-Rex hits around the age of 14 its body size would increase rapidly, putting on around 600kg (1300Ib) a year over the next 4 years.

The first dinosaurs were small, meat-eating animals that first arose over 200 million years ago. From such small beginnings evolved thousands of different species, including the largest animals ever to walk on Earth. At the Smithsonian, some of the most important dinosaurs known to science stand in our exhibit halls, from the ferocious Allosarus to eighty-foot Diplodocus. Learn more about our famous dinosaurs

To create realistic dinosaurs, effects artists had to get in to character. Although Stan Winston Studio created multiple raptors for Jurassic Park, including full-size cable-controlled puppets, half-puppets and insert legs, some Raptor shots were most efficiently captured with a man in a suit (Stan W. school). SWS supervisor John Rosengrant was used as the main Raptor suit performer. Weeks before shooting the raptor scenes, Rosengrant rehearsed in the suit. This Raptor performance was Rosengrant’s first major ‘acting’ role as a suit performer. “I had always wanted to perform in suits. I think to do it well, you have to be a bit of an actor — although, the characters we play usually have a singular mission, which is to kill something. Must eat.

very skinny. By all means, this thing had no right to be alive. He saw the long, razor-like claws that

Because dinosaurs are animals that lived millions of years ago, we are entirely dependent on the fossils that they have left behind for any understanding that we hope to gain. As any paleontologist will tell you, fossil hunting is difficult. There are no certainties, no guarantees. A certain amount of luck is as valuable as any scientific knowledge.

The story of Jurassic Park was written about fourteen years ago by a man named Michael Crichton. His book has now evolved into three movies of Jurassic Park I, II, and III. Steven Speilberg has taken the story of Crichton is transformed it into one of his action packed, suspense thrillers.

            At a time, scientists believed all dinosaurs were cold-blooded.  However, with a recent discovery of a dinosaur found with a fossilized heart in the northern part of South Dakota in 1993, many paleontologists are starting to think that there were some dinosaurs that were warm blooded.

The author is Michael Crichton, and the book is The Lost World. Many people have read this book, along with its predecessor, Jurassic Park, and many people have been enthralled with the thought of living dinosaurs in the 20th century. “What if the dinosaurs did not become extinct? What if they still exist?” (The Lost World takes off a couple years after the first book. A separate island is discovered, an island where the dinosaurs were actually created. There are two different research groups sent to the island. One to observe the dinosaurs in the wild and the other to bring them back for research purposes. The fighting starts from there. What many people don’t know, is that these books, along with countless other
