Tunguska.... and the Dinosaurs?

Question

I understand what happened in 1908, (wether it was an astroid or a meteior) however, what evidence is there that this same thing happened (possibly) and killed all dinosaurs. Sientists are blaming an event at the exact same location, I cannot find any (not even a small amount) of eveidence that would confirm this. Is it true? Web-site? Book? ANYTHING?

Answer 1

It wasn't the Tunguska impact that's credited with wiping out the dinosaurs but a much earlier one from an 8-mile wide asteroid that struck just off the coast of what today is the Yucatan peninsula in Mexico. See this website for a more detailed discussion of this event, along with some great graphics ==>http://www.space.com/scienceastronomy/planetearth/asteroid_jello_001122.html

Answer 2

The Cretaceous-Tertiary extinction event was caused by a large meteorite strike, whereas the Tunguska event probably was not. The Tunguska event was, in any case, much, much smaller, and may have been a piece of ice, or perhaps even a quark nugget.

The Cretaceous-Tertiary meteroite left a huge crater off the coast of the Yucatan Penninsula in Mexico. It also deposited a layer of Iridium all over the Earth.

Answer 3

Cosmo's given you the search term you need - "Cretaceous-Tertiary extinction event". Tunguska's in Siberia though, nowhere near the Yukatan Peninsula. It didn't kill *all* the dinosaurs - birds are believed to have evolved from the survivors.

Answer 4

It is an hipothesis, that of dinosaurs being extinted by an meteorite
(Yucatán, Mexico). But it is not plausible, for it takes ten million years for dinosaurs being extinted. We do not know for certain the cause of the dinasaurs extintion. They lived from 400 million to 65 million years. Some remnants are still living with us, such crocodiles.
