The Discovery Of The Deinonychus Dinosaur

     In recent years other fossil finds have stirred the argument even more. One of these is the fossil named Sinosauroptyrex found in China. It appears to be an important link between birds and dinosaurs. Sinosauropteryx appears to be a feathered dinosaur having a mane of feathers along its neck, back, and tail—a feature until then seen only in birds. Sinosauroptyrex appears before Archaeopteryx and gives a substantial link between the theropods and birds. One opponent of this find is Martin who feels the

Although the Ediacaran period was well before the first appearance of dinosaurs it shows that there were fossils many years ago. When dinosaurs first appeared things had changed there was still shallow water which meant that bones could be fossilized.

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 Bone Wars was a rivalry between Edward Drinker Cope and Othniel Charles Marsh and was also known as “The Great Dinosaur Rush.” This dinosaur rush was during the gilded age of American history with the discovery of over 140 new species of dinosaurs being described and discovered. These two men started as friends strangely enough and ending as bitter enemies with little to no money to their names. The Bone Wars covered a period of 15 years from 1877 to 1892. These two paleontologists ended up using underhanded methods during this time to try and out-compete the other in the discovery of dinosaurs.

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

On the exposed hillsides of the Tsagayan Formation located in Kundur, Russia, a team of paleontologists discovered an almost complete skeleton of a hadrosaurid showing an extensive infection spreading into the shoulders, seemingly stemming from a repaired, but misfigured, fracture in her left front leg. Another piece left behind shows faintly scarred over skin if looked at closely. Surrounding fossils include turtles, protoceratops, and crocodiles. This specimen, discovered to be an Olorotitan, which means giant swan, named so for their longer than normal necks like that of a swan, would be named Odette, from the ballet Swan Lake. This discovery of this sample, proved to have a traumatic lifestyle as a juvenile until their death, allows us

The extinct genus specie dimetrodon live in the early Permian period it was around two hundred and ninety five to two hundred seventy two years ago. The family member of dimetrodon is the sphenacodniate. The dimetrodon walk on four legs also it had a tail, curved skull with very large teeth of many different sizes set along the jaw. Most of the dimetrodon fossils have been found in the southwestern part of the United States. Recently dimetrodon fossils have been found in Germany.

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

Dinosaurs come in many different colors and sizes. The lifespan of a dinosaur is 75 to 300 years. Their daily life is hunting, mating, using the bathroom, and migrating. The defense mechanisms helped them repair their injuries 150 mya. The bone structures are the skull, jaws, neck bones, vertebrae, thigh, pelvis, tail, and rib bone. Dinosaur’s average speed is about 27 mph. Dinosaurs find their food by hunting, which is each other and some eat plants. They reproduce by hatching newborns from eggs. Some communicate by their horns or flickering the tip of their tails. Baryonyx stomach contents were found to contain fish scales, is an example of predator-prey relationship. Some animals that are related to dinosaurs are lizards, because of their skin texture.

Staurikosaurus is a dinosaur within the therapod group. Its name is Greek for “Southern Cross Lizard,” named after a small cross constellation visible in the southern hemisphere. It was named by Edwin H. Colbert and its species name is “pricei,” named after Colbert’s colleague, Llewellyn Ivor Price. Price discovered the dinosaur in 1936 in Southern Brazil, but it was described by Colbert in 1970. Staurikosaurus lived in the late Triassic period, roughly 225 million years ago, making it one of the earlier dinosaurs. It was relatively small, standing only 2.25 meters tall, but stretching to a long 7.5 meters from head to tail. It also only weighed about 66 pounds. While the fossil record of the Staurikosaurus is relatively incomplete, scientists

The Tyrannosaurus rex was one of the most powerful and prevailing dinosaurs to ever exist. These large carnivores lived during the late Cretaceous Period, which was about 66 million years ago. They roamed the lands of which is now present day western North America. Its name comes from the Greek and Latin origins, the word ‘tyrannosaurus’ meaning ‘tyrant lizard’ in Greek, and ‘rex’ meaning ‘king’ in Latin. The infamous T-Rex had a very unique body structure. A massive 5-foot long skull, tiny 3-foot long arms, and an elongated tail to balance the whole body out were not common features among ferocious predators.

Around 100 million years ago, the dinosaur displayed in the hall lived in Argentina. This dinosaur is a sauropod: a massive plant-eater with a long neck and whip-like tail. Sauropods roamed the planet for 140 million years and include the largest land animals ever. The skeleton of a titanosaur includes exact replicas of 84 bones discovered at La Flencha, in Patagonia, Argentina. Missing bones have been modeled, based on analysis of close relatives of this titanosaur. Altogether, fossils of six different individuals are being excavated. Ranch owner Oscar Mayo and worker Aurelio Hernandez reported the find to scientists. Paleontologists realized they had discovered a new titanosaur species based on the shape of the femur and vertebrate. The large size of the femur told them something else: the new species was one of the biggest dinosaurs ever. The titanosaur in the hall was discovered in 2014, and since this species is so new it does not have a name yet. It stands at 46 feet tall and 122 feet long. In addition, to weighing approximately 70 tons, which is equivalent to 10 times an elephants weight he lived 102 million years ago during the Cretaceous Period. Massive animals such as this one usually stand with their legs beneath them to support their great weight, however they can assume other poses. Adult titanosaurs most likely did not have any predators. Lastly, as far as for goes, they strip leaves with their rake-like teeth, then swallow with stopping to chew. Their long

The Titanosaurus is a newly discovered dinosaur well more like found in the year of 2012. The Titanosaurus was found by a ranch owner in Argentina, by the name you could probably figure out that the dinosaur is huge it's 65 feet tall and 131 feet long and weighs about 77 metric tons (170,000 lbs). but that's not all because the ranch owner called a museum to tell them he found some fossils. The American Museum Of Natural History found out that the animals only been underground for little less than a year, it's so recently found that it doesn't have a species name yet. The American Museum Of Natural History also used new technologies were used on this where the bones were actually laser scanned and prototype from the laser again. This went from

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

The biggest mystery surrounding the dinosaur is how did they die? For over 130 million years dinosaurs ruled the earth. Then 65 million years ago, at the end of the Cretaceous period, they died out.
