Velociraptor Research Paper

The big dinosaur t-rex was about 30 feet to 40 feet long and 20 feet tall but can get to 30 feet tall. It lived in the cretaceous period 72 million years ago. It was a carnivore and that means it eats meat it eats more in a week than us eating in 4 months. T-rex is the most powerful with the jaw that can break throw bone.

Australopithecus Boisei: Similar to the A. Aethiopicus in terms of the upper shape with the vertical line of bone

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 first ancestors of the modern horse bore little resemblance to the large, powerful domesticated animals of today. The very earliest ancestor of the horse would have resembled in its appearance the modern-day dog and had many omnivorous rather than herbivorous features, such as its tooth construction and density and its propensity for 'browsing' or foraging. Hyracotherium (or eohippus) measured about 10 inches at the shoulder and had an "arched back, short neck, short snout, short legs, and long tail" (Hunt 1995). It had 'toes' rather than a hoof: 4 toes in the front, and 3 in the back and "low-crowned teeth with 3 incisors, 1 canine, 4 distinct premolars and 3 'grinding' molars in each side of each jaw (Hunt 1995).

Armadillo Lizard is a reptile that can be found only on the western coast of South Africa. Armadillo Lizard live in deserts, shrublands and dry, rocky areas. These animal are collected from the wild and sold in the pet shops around Europe and North America. Armadillo Lizard can reach 15 - 20 inches and about 10 - 20 pounds, also the tail is about 15 inches. The body of Armadillo Lizard is covered with square-shaped scales with a light dark brown on the top of the body and yellow on the bottom of the body. They have a triangular head and flattened body and a tail. A long tube like nostrils, that is well excellent sense of smell for detection of food predators. The Armadillo Lizard have extremely strong bite, also they a change to break their

The Dilophosaurus was a meat eating dinosaur or carnivore. The name of the Dilophosaurus means “Double Crested Lizard” and was discovered by Sam Welles in Arizona, 1942. The Dilophosaurus got its name from the two crest parallel of each other going down its head and the size from head to tail was about twenty feet long and around six to five feet tall it also weight around one thousand pounds. It is believed to have a top speed from anywhere from fifteen to twenty miles per hour due to the powerful hind legs with three toes that were able to move. The Dilophosaurus had small front arms that also had three functioning fingers. The Dilophosaurus was almost as big and deadly as the carnotaurus. The Dilophosaurus was one of the earliest theropods

Trace fossils are able to examine the behavior of the dinosaur. According to Varricchio et al., (2007), dinosaur digging was developed over time. Simpson et al. (2010), reported new evidence of track fossils which indicated that dinosaurs used burrows to hunt for underground mammals. In addition, there were burrows that dinosaurs and mammals used as a shelter for parental investment, cold climate, and predators. This trace fossils were based on observations.

Ichthyosaurs are fish shaped reptiles. These prehistoric creatures ruled over the oceans for 155 million years. Ranging from 245 to 90 million years ago. There are around 80 species known to be make up the group of Ichthyosaurs. These species can be found all over the world because they migrated heavily. The Ichthyosaurs can be compared to a whale, but it isn’t. Ichthyosaurs’ have been found to be two times the size of a person, or as small as a human’s arm length. The creature has a long snout jam-packed with teeth, capable of ripping through prehistoric creatures similar to a squid. Back in the 1800s when the fossils were found its unusual features were noted. A notable feature was its evolution. The fish like creature had evolved from a

Have you ever wondered what a viper looks like?They are so many different colors.They are very fierce and love tropical water and fish they like them.Have you ever seen a viperfish? If you have, you know that they are scary looking.They have sharp teeth that’s how they kill fish.They are mostly three colors.Dark silver and blue and some can have a hint of green.This report about viperfish is going to focus on their appearance,habitat and diet, and interesting facts.

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 Orrorin tugenensis was found with thigh bones. And the Orrorin tugenensis had small teeth like the Australopithicus.

Amphibians were the first tetrapod vertebrates as well as the first vertebrates to live on land. During this interval, this lineage of fleshy-finned organisms moved from the water to the land.

lithographica trotting across the tropical floor was dubious due to the hind wings it possessed, therefore leaving the ground up hypothesis refuted. The factor of metabolism ultimately dictates the prospect of flight. Numerous amounts of scientists theorize that dinosaurs (theropods in particular) were endothermic because of much evidence found in fossils and the locations of those fossils. First, dinosaurs had very sophisticated and upright bone structures, components that show in modern mammals, not reptiles. Dinosaurs (generally small theropods) had a bustling lifestyle. Strictly speaking, in order to be active in the ecosystem, dinosaurs would have to be warm-blooded. If they were not, these antediluvian Sauropsida would almost certainly devote copious amounts of time basking in the sun to keep their body temperatures regulated. Likewise, dinosaurs have been found in arctic regions, a climate that cold-blooded organisms would not expectedly populate. The virtual definition of a dinosaur comprises of reduced forelimbs attached to the posteroventral glenoid and open acetabulum with a supra-acetabular shelf. The latter of which was dematerializing in more recent protoave

The bones of Rodhocetus are very telling of its behavior. The second and fourth fingers (or “digits”) were short and wide; therefore it is thought that these were the digits

Past studies showed the strength of the form and function relationship in the avian furcula, while this study examined the form and function in more modern Mesozoic birds. This study revealed that eigenshape analysis of Arvin birds furcular allows for more derived flight modes. This study confirmed that soaring birds have a more U-shaped furcula than continuously-flapping birds. It also observed that the interclavicular angle is an even more important aspect of flight mode than the curvature, and is positively correlated with body size. This study demonstrates that the Mesozoic taxa have evolved unique flight modes through different musculoskeletal
