Cretaceous–Tertiary extinction event

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…

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…

most to see resurrected. Astonishingly, scientists have actually finagled a way to potentially make this poll useful. Biological scientists have discovered a method to conceivably resurrect extinct animals from their evolutionary graves. Termed de-extinction or species revival, this concept has evoked a substantial amount of social, ethical, and legal friction. Although the…

to Extinction Dinosaurs have captured the whole world’s attention and curiosity. How did they come to be extinct? What factors led to this downfall? Are they completely extinct? All these questions additional to several others have aroused among many scientists. Although the extinction of the dinosaurs was the smallest one it seems to be the most discussed (Meyer, 2016, personal communication). So what was the cause of the end of these grand creatures? In the article “The ‘Great Extinction’…

The excerpt Crash Course (Nancy Honovich) describes what asteroids are and everything about them to how often they occur and how close they have to be to be too close for comfort. At the beginning of the story, it tells about what asteroids are and their history. They even said that a comet called the Shoemaker-Levy 9 sped towards Jupiter at sixty kilometers a second. That is really fast! It also told about how sixty-five million years ago, it is thought that one measly asteroid could have…
