Extinction events

Have you ever wondered what the other half of the world was like? Just like a person can wonder what the 96.5 of the earths water was like. Talking about the mysterious ocean. Did you know it might actually be possible for us to have living dinos in the water, want to know why? Because of the whole theory that a meteor hit earth and killed all living dinos except for some that water dinos were fine and didn’t get effected. So one-day u can discover a megalodon eating your butt But that…

Chicxulub Crater and Mass Extinctions.” This book began talking about the five mass extinctions and what a mass extinction was. It stated that the best studied of all mass extinctions was the fifth mass extinction. This is because it was the closest to us in time, and it wiped out roughly 70% of all species. This lead to the books next topic, how this mass extinction occurred. In the beginning, most scientists were gradualists, meaning they believed the fifth mass extinction happened gradually.…

punishment for breaking sacred law, crashing into Earth and killing everything in the vicinity. And we can still see the scars of this event today. The local people feared if they strayed too close to this land they might reignite some otherworldly creature. Luritja people were forbidden from going near the craters, as that was where the…

About 542 million years ago, an event known as 'The Cambrian Explosion' also known as 'Cambrian Radiation' occurred. It began in the Cambrian period which took place during the Paleozoic Era 542-251 million years ago. It is one of the most significant episodes in the history of life (Conway Morris, 2006). The Cambrian Explosion changed everything. Prior to the Cambrian Explosion, large animals were soft-bodied. Palaeontologists discovered fossils which accounted for approximately half of all…

I'm going to talk about the geologic evidence of the permian triassic extinction. This is a volcanic scenario. There are different geologic reasons for the permian triassic i'm going to tell you about them . During this period there has been documented changes in the air. The atmosphere went evey high which means high levels oxygen was about 30%. When it was low it was about 15%. In this time the salinity in the sea was filled with sharply during the period about 250 million years ago…

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…

The K-T or the Cretaceous-Tertiary extinction, was a mass extinction over unknown origin that took out an 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…

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 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…

they cannot resist it from happens which is extinction of their own kinds. This issue is what most human just ignore about and they tend not to deal with it. History of Earth shows that there are five major extinction events and the fifth extinction is the one that killed every dinosaur on the Earth surface as a result of an asteroid. Earth is now in the eve of sixth extinction as humanity has become the asteroid that would drive species to extinction even quickly than they should be. Marine…
