An analysis of the theories in explaining the extinction of dinosaurs

The dinosaurs may have volcanoes to thank for their domination of the planet, at least according to one theory most scientists think that a severe bout of volcanic activity 200m years ago may. Cleverly following the title of the article, gould presents the theories of colbert, cowles and bogert, which is based on testicular failure of male dinosaurs due to global warming (sex), ronald k siegel, who presumed that massive overdosing due to poisonous flowering plants (drugs) may have caused the extinction of the dinosaur and finally. An analysis of the evidence surrounding the extinction of dinosaur’s reveals that there are several different hypothesis that give theory on what might have happened over 65 million years ago, planet earth consisted of an extraordinary species known as dinosaurs. The asteroid theory has ingrained in the public’s imagination the idea that mass extinction will be quick and sensational—that we will go out in a great, momentous ball of fire big rock from.

The two most popular hypotheses to explain dinosaur extinction are the impact event hypothesis and the massive volcanism hypothesis the first proposes that one or more asteroids struck the earth, causing a “nuclear winter” that wiped out the dinosaurs. An asteroid the most common theory for the demise of the dinosaurs is that a large asteroid struck chicxulub in mexico, forming a 240 kilometre wide crater the resulting atmospheric debris blocked out the sun creating a 'nuclear winter', which killed plants, then plant-eaters and, finally, meat-eaters. A fun science lesson for kids explaining the theories on what caused the extinction of the dinosaurs including a giant asteroid, volcanoes, and an ice age. Dinosaurs had walked the earth for 150 million years before the disaster killed all of them and 70% of other species (dinosaurs extinction) scientists have done a lot of research in order to explain the reasons why dinosaurs went extinct, but the result still remained unclear.

But before our current view came together, the extinction of the non-avian dinosaurs was an open-ended question here is a list of some of the stranger—now discarded—theories explaining the. Another theory that was presented about the extinction of species like the dinosaurs was that during the cretaceous period, there might have been an overpopulation of species this might have contributed to severe competition and rivalry among species like the dinosaurs. This event changed the planet’s climate and is widely believed to have triggered a mass extinction of species — including the end of the dinosaurs clay fine-grained particles of soil that stick together and can be molded when wet. Re: q19 - one theory to explain the sudden extinction by kjsmit02 wed may 06, 2015 9:52 pm mattsherman wrote: answer choice (a) undermines the causal conclusion by providing an example of the presumed effect without the presumed cause. 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.

After all, the mass extinction during the triassic cleared the way for the dinosaurs, and the mass extinction that ended their reign ushered in an era of mammals -- allowing our own species to evolve. One theory that explains the extinction of dinosaurs is the ice age theory, which states that an ice age, which changed temperatures dramatically and froze waters, killed the dinosaurs, as they were not able to stay alive under these conditions. According to this theory, too many meat-eating dinosaurs evolved, eating all the plant-eaters, causing all dinosaurs to die these ideas have the same pitfall described earlier they explain dinosaur extinction but ignore the extinction of other groups.

An analysis of the theories in explaining the extinction of dinosaurs

Some experts have long believed that a massive asteroid was a primary cause of dinosaurs' extinction some 65 million years ago, but new analysis from a university at albany psychology professor. 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 apparently sudden mass extinction of dinosaurs marks the boundary between the cretaceous and tertiary periods though there is not one definitive explanation to explain dinosaurs' extinction, there are various theories that attempt to account for the mystery of their extinction. The dinosaurs were more diverse in form and function by the end of the cretaceous period (before the extinction) than in any other time if the dinosaurs had a peak, it was at the time of their.

  • The extinction of the dinosaurs is an import issue that can shed light on the repeated as well as the end of the reign of the dinosaurs many theories have been proposed to explain the physiognomic analysis of leaf assemblages across the kt-boundary in the north american.
  • The disappearance of the dinosaurs remains to be one of the most disputable topics, discussed by hundreds of scientists and researchers all over the world although there are many different theories on the extinction of dinosaurs, all of them still have plenty of inconsistencies and questions.

Possible theories many of these theories have some element which makes them in some way reasonable however often they can only be related to a specific types of dinosaur, such as herbivores or carnivores, or to those which lived in a certain habitat. The leading theory for what caused the extinction of the dinosaurs was a huge asteroid that hit the earth in present-day mexico 66m years ago but exactly how that triggered the mass extinction. The extinction “could have been a one-two punch,” said bruce s lieberman, a paleontologist at the university of kansas and a co-author of the theory “our theory builds on earlier theories.
