Cretaceous

moves from layers of rocks documenting the end of the Cretaceous up into rocks representing the beginning of the Cenozoic. Between the last layer of Cretaceous rock and the first layer go Cenozoic rock, there is often a thin layer of clay. Scientists thought that calculate the amount of iridium in the clay could find how many time were needed to create the layer. Luis realized that sedimentary layers found all over the world at the Cretaceous–Paleogene boundary contain a concentration of iridium…

lizards and other small animals. It could also be a scavenger. When the velociraptor hunted in packs though it could take down much larger dinosaurs like the hadrosaur. It also ate smaller dinosaurs like pterosaurs. The velociraptor lived during the cretaceous period. Its fossils have only been found in one place so far, which is Mongolia. The velociraptor was one of the most intelligent dinosaurs of its time. It could hunt in packs or alone. It ran on 2 legs and was very fast. Its name means…

2.4. Hydrocarbon potential Previous work reveals presence of mature sedimentary sequence was derived from Jurassic to lower cretaceous periods in the north part of Lake Malawi which has hydrocarbon reservoir prospects. Existence of thick sedimentary sequence rock could possibly trap hydrocarbon especially in lower Shire valley, northern of Lake Malawi. Presence of large proportion volcanic clasts interbedded with sedimentary rocks transported by rivers present for extensive alluvial plain…

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…

also occurred during these eras. Dinosaurs dominated and reigned supreme on this our home called earth from the late part of the first sub-era of the Mesozoic era called the Triassic sub-era (230-201 million years ago) to the last sub-era called Cretaceous sub-era (145-66 million years). The three sub-era of the Mesozoic era…

For approximately 160 million years, the terrestrial environment was dominated by dinosaurs. Dinosaurs arose from fully bipedal ancestors, who is believed to have been a carnivore or omnivore (Langer, Ezcurra, Bittencourt & Novas, 2010). These agile terrestrial archosaurs lived during the Late Permian and Early Triassic and had already developed key changes in the hips and ankles that set the stage for the increase in body size that is seen in dinosaurs (Pough, Janis & Heiser, 2013). This…

Triceratops are one of the most famous types of dinosaurs. They have been named the state fossil of South Dakota and named the state dinosaur of Wyoming. A person can watch Triceratops interact with other dinosaurs in the movie Jurassic Park and read about them in many children’s books (Triceratops Wikipedia). Triceratops are part of the Ornithischian family. Triceratops were named by Orthniel Marsh in 1889 after some brow horns were found near Denver, Colorado in 1887 (Fastovsky). This…

fossils, and modern science. When I entered the Hall of Ancient Life there was a life-size cast of dinosaurs all over the gallery, including a 40 foot long skeleton of an Acrocanthosaurus that I learned existed in North America during the early Cretaceous period. I even got to learn fun facts about some of the dinosaurs that I didn’t know before like the Triceratops it was one of the last surviving species of ornithischian dinosaurs that belonged to a family of herbivorous dinosaurs called the…

According to scientists, the Sauropoda was thought to be alive during the late Triassic period, which was roughly 65 million years ago. As a result of scientist’s theories, they believe that the Sauropoda was killed of at some point during the cretaceous period. Sauropoda means,”Lizard footed”. Because scientist have found more and more information about these dinosaurs, they are still coming up with different theories. The Sauropoda had a very long neck to help them reach different plants and…

extinction causing the majority of a planet’s population to die? Newton’s laws of motion can explain how and why a asteroid caused a mass extinction wiping out an entire planet’s evolution. Scientist have multiple hypotheses leading to the end of the Cretaceous Era or T-K event. One of such, is the astronomical event that hit the earth sending an immense amount of debris and dust into the air clogging the skies, leading to a major climate change known as the Ice Age. The Ice Age killed off a…
