Physical Characteristics Of Staurikosaurus

While the author of the article believes that Brachiosaurus were aquatic animals, the professor disagrees with this statement. The professor points out that in spite of the fact that some species of dinosaur would spend a great deal of time in water, there was no possible that Brachiosaurus were aquatic ones. To strengthen her point, the professor provides sufficient evidence respectively to the points made in the article.

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.

While a theropod “beast-footed” carnivore includes the T. Rex, the ones that likely roamed Wrangel-St.Elias National Park were considerably smaller. The researchers found evidence of a single theropod that was likely a tiny 9 cm long and 7 cm wide due to an impression of the sinusoidal shape. Several ornithopod, medium and large plant-eating dinosaurs, was identified by blunt and rounded digit impressions which are usually 22 cm long and 26 wide. It was the first evidence that dinosaurs roamed this vast region.

The elongated arm bones that support the wing evolved in the first coelurosaur, which probably looked like ornitholestes. As far as we know feathers are unique to birds, but this doesn’t mean that birds are not dinosaurs. Because birds belong to the group called dinosaurs, it follows that birds are feathered dinosaurs. The closest known evolutionary relatives of birds are some of the small carnivorous dinosaurs, such as velociraptor, ornitholestes, and deinonychus. The difference between a Tyrannosaurus Rex and Apatosaurus is that almost everything about Tyrannosaurus Rex indicates enormous power of one of the largest theropod dinosaurs that ever existed. They have a 4-foot-long jaw, 6-inch-long teeth and massive thighbones. It is the largest and most fearsome carnivore of all time. The fossil was originally arranged so that the dinosaur stood

These dinosaurs were discovered in the Shandong peninsula, which is the exact reason for its name. Also discovered in 1973 by a man named Hu. They were known to be the biggest ornithischian. This dinosaur had over 1,000 teeth and though they only used them toward eating plants. They weren’t the fastest but had the ability to sprint in order to get away from predators. They also spent their time traveling in herds in order to stay safe due to predators always on the prowl. These dinosaurs were smart enough to know that they would have strength in number and due to their size. They were known to stand their ground and had the tools to fight but when a large predator came lurking by like a Tyrannosaurus Rex, they knew their best chance of survival was to vacate the area. These massive dinosaurs stood at 25 feet in height, 54 feet in length, and weighs about 15 tons. Shantungosaurus was a very distinct dinosaur, definitely not like any other dinosaur around. But they were able to defend themselves and did so using teamwork and if they couldn’t win they were able to run away. They were able to go on their two legs and sprint. Also they had a tail that was really long and the biggest purpose of this tail was to keep them balanced, though it was thought this tail was used for aquatic reasons but it was later found that this was not the case due to the structure of the tail. The simple fact is we can only know so much about these dinosaurs; we weren’t there, so how could we really know what these dinosaurs

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?

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

Stegosaurus is a genus of armored dinosaur. Their fossilized bones have been found in rocks dating to the late Jurassic period, between 155 and 150 million years ago, in the western United States and Portugal. Colorado is when the very first Stegosaurus fossil was found in 1876. Stegosaurus was designated the official state fossil of Colorado in 1982. Colorado is where the the very first stegosaurus fossil was found in

In the website http://nationalgeographic.org/media/pterodactyl-fossil/ they said quote “Pterodactyls were not dinosaurs! Dinosaurs are generally considered to walk upright, on either two legs (like T.Rex) or four legs (like stegosaurus). Pterodactyls

Now, there are a lot of questions related to wether or not large theropods like Tyrannosaurus rex for example were totally covered in a dense coat of feathers or where totally scally creatures. Some say being so large it would have been a disadventage fot a "fluffy" T-rex, because it will have been suffering of overheating, but feathers are very different from the hair of mammals, the structure of feathers allow large birds like the ostrich to discipate the heat from the body if the external temperature is so hot (very similar to the mecanisms that modern afrinac elephants have with their large ears!). So large meat eating dinosaurs would have lived very well with a dense coat of feathers even if their environment was very hot (of course the case of a "fluffy" T-rex is still in debate, some think thet T-rex would have beel partially covered in proto-feathers and scales, but wheter of both scenarios, large theropods would have developes mecanisms for losing heat, see link below the

First, I would like to point out that the word dinosaur was not even invented until 1842 by Richard Owen in Plymouth, England. The word comes from the Greek words deinos, meaning fearfully great, and sauros, meaning lizard, which translates to fearfully great (or terrible) lizard. (Smithsonian Institute) For many centuries, before the word dinosaur was invented, these terrible lizards

The mosasaur is generally described as being a bit like a cross between a giant monitor lizard and a snake. Its body was shaped similarly to modern day monitor

First, Crichton noted that duckbilled dinosaurs were herbivores which are supported by a trace fossil found in the coal beds of the western North America that indicated footprints with plant fossils (Martin 2006). Furthermore, duckbilled dinosaurs lived in a vegetated environment that they had to consume enough food relative to their body size. Duckbilled dinosaurs had lengthened their skull and smoothed snout to obtain and process more food. The Dilophosaurus was described as two curved crests that extended from the eyes to the nose. The crest created a V shape on the head with red and black stripes on the crests (Crichton, 1990). Based on fossil evidence, the Dilophosaurus had two crests on the head, but there was no indication of the pigment of the crest. Next, the book stated that the T. rex does not bite the prey, instead, it twisted and tore the
