Feathered dinosaurs

million years ago, that wiped the dinosaurs off the face of the Earth? Asteroids can range from the size of a small rock, to the size of a dwarf-planet. “Currently, the largest asteroids listed to date primarily reside…

All the three papers by Benton (1995), Erwin (2001), and Barnosky et al. (2011) talked about the impact of mass extinction on the biological history of earth. Benton (1995) talked about how mass extinction drives diversification in the biological community, Erwin (2001) discussed on how species recovery occurs after mass extinction and Barnosky et al. (2011) talked about the possibility of future mass extinction based on the comparison between the present and past extinction data.…

To begin with, 65 million years ago was the start of the Paleocene epoch that was the establishment of the tertiary period on earth. Due to the extinction of the dinosaurs during the previous period, there was a heap amount of mammals accumulating and evolving from their original size and aspects. Many forms of animals existed big, small, and of many different sizes; rapidly increasing in numbers by reproduction. In this epoch, carnivores were very large in numbers. For example, a bird that was…

My animal is a spinosaurus, it went extinct millions of years ago because it is a dinosaur.This animal grow grow in length to be about 40 feet long.In heighth it grew to be about 20 feet tall. This animal has spikes on its back that grow to be about 5 feet tall they kinda look like fins like on a fish. This dino can swim under water and holds its breath for a long time if needed. It has a darker green type of skin color. And it has a long head. The spinosaurus was able to swim real good…

estimated 60-75 percent of all the species on earth 66 million years ago, most famously the dinosaurs. It was the end of the Cretaceous period and the Mesozoic Era and created the beginning of the Cenozoic Era that is still happening today. Geologically speaking this extinction happened in a very short amount of time. Although the most well known species to go extincted during this time was the dinosaurs there were also many other species that went during this time. On land many different types…

Grant returns to the island on what he thought was a vacation however; he later discovers that he is helping the couple find their lost child Eric. Once Eric is found the group has to avoid getting eaten by dinosaurs and escape the island. Due to the actions of one individual stealing a set of dinosaur eggs escape is made all the more difficult when they realize they are being hunted by raptors to retrieve their stolen eggs. Eventually the group…

Therapsida – *Therapsida is a group of synapsids, and includes mammals and their ancestors. *They were advanced mammal like reptiles that appeared during early Jurassic and became dominant land animal during middle Permian period. *They evolved from a group of pelycosaurs called sphenacodonts. *The legs are positioned more vertically…

The reading claims that large pterosaus were capable of powered flight, however, the professor find all the ideas mentioned by the reading passage dubious and think that they may were capable of powered flight and present some reasons to refute them all. The author argues that pewrosaus were cold blooded since modern reptiles are cold blooded too, therefore they were not able to produce a lot of energy which is needed for powered flight. Conversely, the lecturer brings up that this reason is…

the dinosaurs. It mainly exposes the two alternative hypotheses that might have caused this mass extinction by explaining the main reasoning behind each of these premises. The author exposes the points of views of different scientists and geologists in regards to the death of the dinosaurs, which- somehow- remains one of the most heated and contested “battles in science”. Particularly, the paper explains the stance of one geologist from Princeton who is an advocate of a different dinosaur…

With their scaly bodies, slit eyes, and long tails, alligators and crocodiles look a lot like dinosaurs. In fact, alligators and crocodiles descending from the same family as dinosaurs while it’s true that alligators and crocodiles look a lot alike, they differ in three ways. First, alligators and crocodiles are found in different parts of the world. Alligators are found in China, Central America, and South America. On the other hand. Crocodiles are found in Africa, Australia, Southeast Asia,…
