The Scene Opens On A Watering Hole

3 years later in 1903, paleontologist Elmer S. Riggs named the fossil remains. A few years later in 1909, there was yet another discovery of a Brachiosaurus by Werner Janensch in Tanzania (“Brachiosaurus,” 1996). Today after years of excavations of fossils and bones of dinosaurs, the Brachiosaurus is widely considered to be one of the largest dinosaurs due to its height of 40 feet, weight of 80 tons, and length of 80 feet. However in comparison to the mere size of the Brachiosaurus, its feet were small and narrow and its hind legs were short. In addition, its jaw was strong and contained large teeth. As well as having small narrow feet and short hind legs, the Brachiosaurus' snout was flat with large nostrils located at the top of its head. However, the use of the Brachiosaurus' nostrils still remains a mystery and lots of speculation still surrounds it to this day (“Brachiosaurus,”

In a study published in Cretaceous Research and conducted in October 2012 by Anthony R. Fiorillo, Thomas L. Adams and Yoshitsugu Kobayashi, evidence of dinosaurs was based on the finding of an unnamed nonmarine sedimentary package of rocks. Found in the Wrangellia Terrane and considered to be Cretaceous age, the rocks are light colored with medium grey shales and indicate a bounty of horsetails, ferns and gymnosperm wood.

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

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 Tyrannosaurus, also known as the T-Rex, are some of the biggest carnivores that roamed this planet. A large one would weigh about 6,000 Kilograms. A large T-Rex was 12.3 meters long. It could crush bone with a single bite. It ate the big 3 witch are the Hadrosaurs, Ceratopsians, and Ankylosaurus. In the stereoscopic arc(witch is where both eyes meet) the T-Rex could see 3-D. It’s name means tyrant lizard. The T-Rex was tall but not the tallest carnivorous dinosaur.

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 reading states that the researchers deliberately broke open the Tyrannosaurus rex's leg bone and found remains of blood vessels, red blod cells, and collagen matrix and provides three reasons of support. However, the professor states that it's skeptical that T.rex has all of structures and refutes each of the authors' reasons.

Additional evidence of aggression is demonstrated by a tyrannosaur tooth embedded in a confamilar’s mandible. A Gorgosaurus or Daspletosaurus was attacked by another tyrannosaur. The tooth embedded matches the size and shape of a large, adult tyrannosaur. The lesion was unhealed, suggesting that the damage occurred either at the time of death or post mortem. This lack of healing indicates that the dinosaur either died during this attack or its corpse was later scavenged. It is not likely that this was fatal but may have inflicted enough damage to weaken the dinosaur. Neither the genus nor species of the attacker is known. Since it is only known that both dinosaurs were tyrannosaurs, this could be, at the very least, an instance

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

The Discovery of the “new” T-Rex occurred during the blistering heat of a Ganzhou summer by a construction worker in the city. Obviously, it was not a paleontological expedition, but it quickly turned into one after the worker’s backhoe slammed into a rock-hard barrier. Though the man likely assumed it would be a major inconvenience for his job (such as bedrock or pipes), but he was in for quite the surprise. Amidst the dusty, dirty air, the skeletal remains of a new species of Tyrannosaurus Rex lay idly by- just waiting to be discovered. That is right, the Qianzhousaurus Sinensis, in all the glory of its long snout, was revealed completely by accident.

The Tyrannosaurus is part of the Tyrannosauroidea family. My grandpa says their also part of the family of chicken. They were about 40 feet long,15 to 20 feet tall, and their arms were about 3 feet. They were 5 to 7 ton in weight and their head was five feet long that’s almost as big as me.

The newly found dinosaur is estimated to be 30 feet long, a plant eater and is a member of the duck-billed dinosaurs. Gregory M. Erickson, a professor at Florida State University and also one of the researchers working on the Alaskan site, describes that it had “at least 1,000 teeth with coarse surfaces perfect for pulverizing plants” and had “crests along its back like Godzilla” (Erickson, 2015). It is interesting how paleontologists could determine whether a certain fossil was herbivore or carnivore when they were still alive by just looking at teeth. The article also mentions that it is probably covered in scales and that it could walk in all fours. This is also another example on how paleontologists can analyze and observe a fossil and

Animal fossils usually provide little information to study. Recently, there is a discovery that the T rex’s leg bone insides reveal some materials that seem to be remain of blood vessels, red blood cells and collage matrix. The lecture and reading passage discuss if the materials are blood vessels, red blood cells and collagen marix. The lecture puts forward three points and effectively contradicts the opinions of the reading passage.

First, the writer believes that the fossils of the dinosaurs have been discovered in polar region and only the endotherms can maintain their temperature in that situation; nevertheless, a lecturer claims that such a theory is not true. Because on that time, there was a warmer temperature in the environment which dinosaurs can live. Moreover, in the cold time, they could have migrated or even hibernated.

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
