Permian–Triassic extinction event

Brontosaurus Othniel Charles Marsh discovered and named the Brontosaurus (Greek “thunder lizard”), a four-legged dinosaur in 1879. With at least three known species, this dinosaur lived in the Morrison Formation of present day Western US, during the late Jurassic Period and became extinct by the end of the period. Perhaps one of the most controversially classified dinosaurs, paleontologists have reclassified the Brontosaurus several times since its discovery to an extent that some quarters…

believed to be wiped out by a meteorite/asteroid or another catastrophic event. How did an asteroid cause a mass 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…

Our planet is in the middle of the sixth mass extinction of mammals, fish, amphibians, reptiles, birds and plants. We are currently experiencing the worst case of extinction than the dinosaurs which was 65 million years ago. Extinction may be a natural event but there has been a recent increase of species extinction from 1000 to 10,000 per year. This means in the future we may lose species every day [1]. Before extinction was caused by earthquakes, volcanic eruption and climate change but this…

DAYER prologue Long time ago before dinosaurs an evil, merciless species reign happened, They were the Dayers. The Dayers possessed an enormous powers, but they never knew their capacity. They could transform into infinity numbers of power level, but as time went by dinosaurs came along, and as dinosaurs’ population aggressed, dinosaurs started dominating the Dayers. Even one Dayer is able to win a fight against 1,000 dinosaurs if they had developed their skills of fighting.Now those…

Almost 70 million years ago, the most recent of apocalyptic extinction events occurred, wiping out the dinosaurs and signaling the start of a new era. The Cenozoic Era (age of mammals) has been split into seven sections called epochs with the final epoch being called the Holocene epoch, which brought forth a new ecosystem that harbored humanity. To conclude the eras that occurred previously, there have been five apocalyptic extinction events that occur roughly every 100 million year, and…

Why did dinosaurs disappear? There are three main theories that explain dinosaur’s extinction, and they each have crucial evidence to support them. These are the mysteries of the dinosaurs. The extraterrestrial theory, or the asteroid theory, was created by a team of scientists that sought out evidence and came to an astronomical conclusion. They discovered that…

Picture yourself standing among the various dinosaurs 252 million years ago, when hurtling from the sky a massive meteorite colliding into the earth resulting in one of the largest mass extinction to come, commonly referred to as the Permian-Triassic extinction, in Earth’s history shifting Earth into a new era: The Mesozoic Era. Frequently mentioned to as “Age of Reptiles” due to the amount of reptiles that predominated the lands, however they were not alone; land-dwelling vertebrate animals and…

that there were some common factors separating these groups. One of the largest contrasts discovered was that one hundred percent of concerned believers feel that climate change is man made, while one hundred percent of cool skeptics believe that the events of global warming are natural changes in the planet. Furthermore concerned believers are more likely to feel that the news on global warming is either correct or underestimated. Cool skeptics on the other hand think that the news on climate…

The Massest of Mass Extinctions With all the post-apocalyptic themed movies coming out of Hollywood, most people are probably familiar with the concept of a mass extinction. In those kind of movies the cause is often a manmade problem, such as nuclear war. However, in the earth’s distant past, we were not around to destroy ourselves. So what happened? 250 million years ago the Permian period came to an end in a mass extinction causing 95% of species living in the ocean to die (Cort, 2006). To…

the temperature lower down abruptly. Dinosaurs could not adapted this situation and extinct.(Joerger Fall(2011), Science Illustrated Magazine, Germany) To sum up, these are the main four theories to account for the dinosaurs extinction. Although the truth of dinosaurs extinction has not been proved, I believe people can solve this question in the future because the highly developed science and…
