Among some of the earliest of dinosaurs to evolve, Unaysaurus tolentenoi was a prosauropod found in the Caturrita formation in what is now Brazil. In life, it would have reached lengths of up to 2.5 meters (about 8 feet) long, weighed up to 70 kilograms (about 154 pounds) and, reached a height of about 80 centimeters (about 2’ 7”). Its genus name means “black water lizard” while the species name comes from Tolentino Marafiga, who discovered the remains on the side of the road. Being the…

1. The movie Life on Earth focused on how fossils are glimpses of a distant past because they explain how life evolved on earth. They also used a Cladogram to explain the cladistic relationship between a number of species. The first organism with a nucleus lived one and a half million years ago. An animal with a braincase and a beginning of a backbone appeared 500 million years ago. Amniotes were split into two main lineages. One is identified by a hole that evolved in the skull behind the eye…

measure the magnitude of extinctions: simple counting, percent extinctions, total and per family extinction. From the percent extinction measurement, he identified five deadly mass extinctions at Late Ordovician, Late Devonian, Late Permian, Late Triassic, and Late Cretaceous. These five big mass extinctions were mentioned also by Erwin (2001) and Barnosky et al. (2011). Barnosky et al. (2011) measured the big five mass extinctions based on proportional rate (number of species extinct/time) and…

extinctions. These mass extinctions are said to be a normal part  of life and might even be an important factor for life on Earth. The main mass extinctions that have been discovered are the Ordovician Mass Extinction, the Devonian, Permian, Triassic, and the Cretaceous Mass Extinction. Scientists now even believe that we are not only part of the problem but the main subjects of the sixth mass extinction caused by Homo sapiens (humans). Andrew Jones had even stated that it’s as if we…

Way back when, humanity had such a strong past. Nothing appeared. Time was time. Nothing is nothing. The four eras that made history. Precambrian, Paleozoic, Mesozoic, Cenozoic. Historians and Scientists, did research for years and years. What happened during the Precambrian Era, nobody had a clue. Until humans researched the resources left behind. Back in the Precambrian Era . Earth was born. 4.6 million years ago, not even that many.! Stars and the planets were too! Rocks and much…

saurophagis, which scaled up to at least 28 feet long and could be compared to a bus. This creature was considered in the group of ichthyosaur which was a group of reptiles that dominated the seas while the dinosaurs were roaming the earth during the Triassic period. The creature was discovered in Nevada. The fossil of this creature was located in 1988 and the fossil held almost the entirety of it. One explorer from National Geographic claimed that is impeccable to see…

TECTONIC HISTORY The Smackover Formation of Texas is located in the East Texas Basin, in North-East Texas, and is “one of three Mesozoic basins flanking the northern rim of the Gulf Coastal Plain” (Foote et al., 1988, p.3). “Subsidence from rifting and crustal attenuation in addition to subsequent sediment loading results in a maximum of 23,000 feet of subsidence in the center of the basin” ( an idea originally published in Seni and Jackson,1984, quoted from Foote et al., 1988, p.3). The area…

INTRODUCTION The human population on Earth has been growing at an alarming rate bringing with it an ever growing need for food, energy and land use, amongst many others. At the same time, the list of animal species recorded as being extinct or on the verge of being extinct gets longer and longer. Is this phenomenon coincidence or are these two occurrences directly link to each other? This research task aims to investigate if there is reliable proof that human population growth and species…

The exhibit Evolving Planet showed how one period led to another. It gives evidence of changes and adaptionsThrough each time a person can see that there were similarities between animals and how they adapted to fit into that period. In the Quaternary Period during the Ice Age I saw what was called the Giant Ground Sloth which is a much bigger version of sloth that we see today. They evolved in the South American grasslands and then later migrated to North America. They could survive cooler…

What do you get if you cross a pig with a dinosaur? Jurassic Pork! (jokes4us.com) Most people in the world today do not realize how much they impact the ecosystem. Some people do not even have the knowledge about the ecosystem and how it affects the world we live in, and then there are those people that just do not care about the ecosystem. An ecosystem is a community of animals, people, and plants that interact with one another and their physical environment. One type of ecosystem that we take…
