Cretaceous Paleogene Extinction Prompts Stable Diffusion Online Based on studies at seymour island in antarctica, sierra petersen and colleagues argue that there were two separate extinction events near the cretaceous–paleogene boundary, with one correlating to deccan trap volcanism and one correlated with the chicxulub impact. K–t extinction, a global mass extinction event responsible for eliminating approximately 80 percent of all species of animals at or very close to the boundary between the cretaceous and paleogene periods, about 66 million years ago.
Dinosaur Extinction Inside The Cretaceous Paleogene Event The cretaceous–paleogene extinction event was a significant mass extinction event that occurred approximately 65 million years ago, marking the boundary between the cretaceous period and the paleogene period. this event is widely attributed to a cataclysmic impact from a large asteroid or comet, estimated to be about six miles wide, which struck the earth at what is now the yucatán. The cretaceous paleogene mass extinction, occurring approximately 66 million years ago, represents one of the most dramatic biotic crises in earth’s history. In january 2020, scientists reported new evidence that the extinction event was mostly a result of the meteorite impact and not volcanism. other causal or contributing factors to the extinction may have been the deccan traps and other volcanic eruptions, climate change, and sea level change. These mass extinction events have also accelerated the rate of evolution of organisms on earth. the most recent of the five events is the cretaceous paleogene extinction which took place about 66 million years ago.

Key points: •the disappearance of non avian dinosaurs was just one part of a larger event: the cretaceous paleogene (k pg) mass extinction (formerly called the cretaceous tertiary or k t extinction). •diverse groups of land and sea organisms died out at this time, 66.05 million years ago. Mass extinctions are typically followed by evolutionary bursts or radiations within surviving groups of organisms, such as mammals after dinosaurs became extinct at the end of the cretaceous. The results of this study, which were based on estimated real global biodiversity, showed that between 628 and 1078 non avian dinosaur species were alive at the end of the cretaceous and underwent sudden extinction after the cretaceous–paleogene extinction event. This cataclysmic event that wiped out 75% life on earth, including the dinosaurs. this documentary recalls the events of this major event in world history as it happened.
