One of paleontology\'s favorite puzzles is the mass extinction of the dinosaurs

Question

One of paleontology's favorite puzzles is the mass extinction of the dinosaurs (and many other kinds of species which lived at the same time). Currently, the most popular explanation for this is the "impact" hypothesis. Review the Stephen Jay Gould article to brush up on the nature of this proposal. This is actually a suggestion of an ecological disaster. Explain what this hypothesis is suggesting in terms of the structure of an ecosystem, with particular reference to trophic pyramids. Though many, many groups of organisms suffered greatly during this mass extinction, most apparently left some surviving species to radiate into the vacated niches. Why do you suppose the dinosaurs suffered such a complete disaster. (Well, except for the birds, of course). In other words, why were the dinosaurs apparently particularly vulnerable to this kind of disaster?

Explanation / Answer

Extinction events that paleontologists have identified on the earth

The hypothesis that the terminal Cretaceous(dinosaur) extinction was caused by a cosmic impact that has been most popular explanation of this catastrophe among earth scientists and the public for several decades Netherlands published a evidence geologically brief episode of cooling which they claim as first direct evidence of impact winter

Whatever the outcome of debate it seems clear that the end of Cretaceous with its super volcanoes and giant impacts was not a good time for life on earth.evidence shows that there was a hyperthermal period of rapid warming that increased ocean temperatures by 3-4 temperatures

She claimed that temperature remained elevated throughout hyperthermal warning of oceans by 3-4 degrees celcius.this hyperthermal warming occurred within a 10000 year period of mega eruptions which corresponds with the Cretaceous extinction
