Meteors came hurtling to earth and stopped life as they knew it for the dinosaurs complete and instantaneous extinction is no longer the theory.

The most well-known major extinction of creatures is that of the dinosaurs some 65 million years ago at the end of the cretaceous period, a meteorite hit the yucatán peninsula, causing widespread climate change and environmental disruption. The cause of the mass extinction that marks the end of the cretaceous and the beginning of the paleogene is a scientific mystery the extinction wiped out the dinosaurs while most mammals, turtles.
The last dinosaurs died approximately 65 million years ago although the cause of their extinction is still a mystery, climatic change, diseases, changing plant communities, and geologic events could all have played a role lately, dinosaur extinction theories have been the subject of much debate. The extinction of the dinosaurs michael j oard abstract dinosaur extinction is still a major enigma of earth history in this review article, extinctions in the geological record will be briefly mentioned. Transcript of extinction: what killed the dinosaurs look at the words in the column on the left these are words from the unit 5 companion dinosaur extinction theories and the k-t boundary e: how is the k-t boundary defined the time between the tertiary and cretaceous eras when a mass extinction occurred f: why is the montana area in. Regression, caused extinction on the basis that all dinosaurs were marine creatures perhaps not applicable to flying dinosaurs perhaps not applicable to flying dinosaurs transgression caused the bottom of the oceans to become stagnant and lacking oxygen, which is essential for breathing.
The cretaceous–paleogene (k–pg) extinction event, also known as the cretaceous–tertiary (k–t) extinction, was a sudden mass extinction of some three-quarters of the plant and animal species on earth, approximately 66 million years ago. The bible gives us a framework for explaining dinosaurs in terms of thousands of years of history, including the mystery of when they lived and what happened to them many think that the existence of dinosaurs and their demise is shrouded in such mystery that we may never know the truth about where. If the extinction was intrinsic and gradual, both processes probably played a role also note that the basic theory here is an elaboration of the 'dinosaurs faded away' hypothesis from the invalid hypotheses section it adds a factor of causation that is quite convincing.
Extinction of the dinosaurs this is perhaps the greatest controversy surrounding the dinosaurs the various theories of the extinction of dinosaurs have only one thing in common: the fact that, except for birds, dinosaurs died out completely and suddenly 66 million years ago, after having been very successful animals for about 160 million years. Theories of extinction of course, that method of extinction wasn’t always favored by scientists when i was at school—back in the olden days, as my son is keen to point out—i was taught that the dinosaurs died out because their eggshells were getting gradually thinner, so that they started being eaten up by naughty, furry mammals. Theories on dinosaur extinction what killed the dinosaurs several theories have been brought up over time to answer this question it has been of vast interest to many scientists how creatures the size of the dinosaurs could have been wiped out of existence. Also, they only look at data for the last 250 million years, which barely includes the end-permian extinction the late ordovician event, the second most severe extinction known, and the fourth worst event, the frasnian/famennian extinction, lie nowhere near a 26 million year periodicity, at 448 and 367 mya, respectively. The extinction level event could have caused most of the dinosaurs to devolve into savagery and eat each other to extinction a flesh eating plague perhaps after all, a few fossils and old rocks are science the picture and behavior models are just fiction.
Dinosaur extinction theories two main theories exist in paleontology (the study of dinosaurs) today, each having a different view of what killed the dinosaurs and other organisms at the k-t boundary k-t stands for cretaceous-tertiary, which marks the time between when dinosaurs existed and when they were extinct. Possibly, both these indegistible plants (for dinosaurs, at least) and toxic flowers could've existed at the same time, pushing the dinosaurs even further into extinction without herbivores to eat, the cfieldores died out as well. Extinction of the dinosaurs is a great mystery when the dinosaurs became extinct, many species like crocodiles managed to survive scientists will continue to produce theories about this great extinction.
Paleontologists have long pondered what caused the extinction of the dinosaurs 66 million years ago and came up with some crazy theories while a spy proposed the dinosaurs suffered from. Dromaeosauridae (raptors) are really the only group with fossil evidence of feathers speculation about other all other therapods is mostly extrapolation following the discovery of shuvuuia with tube-like structures resembling the rachis (central vane) of modern bird feathers. Dinosaur extinction is a big mystery, as although dinosaurs died out at this time, many species survived, including similar animal types like crocodiles new discoveries scientist have come up with some strange ideas but none of the theories really explains everything, so we will probably never be sure what happened.
A theory set in stone: an asteroid killed the dinosaurs, after all a single asteroid impact near the yucatan remains the best explanation for the massive cretaceous-paleogene extinction. The end of the dinosaurs: the k-t extinction almost all the large vertebrates on earth, on land, at sea, and in the air (all dinosaurs, plesiosaurs, mosasaurs, and pterosaurs) suddenly became extinct about 65 ma, at the end of the cretaceous period. Dinosaur extinction dinosaur extinction: another theory dinosaur extinction is a hot topic for debate new theories for the catastrophe that killed the dinosaurs are presented every couple of years.
