When did most of the dinosaurs die, the quick answer is that they went extinct about 66 million years back (MYA).

Geochronologists establish accurate dates for occasions that happened eons ago

But no one can check that date by consulting a past history b k or glancing at a calendar or even a clock.

So just how how is it possible to determine a romantic date for the loss of dinosaurs that long ago? For example, how ended up being it feasible to identify age the fossil that is famous Lucy, unearthed in East Africa in 1974, at 3.18 MYA?

Numerous fossil bones l k much alike, whether their owners had been striding around East Africa 200,000 years back or three million years ago. However with an accurate age, a fossil bone or a stone device can squeeze into a meaningful niche in our developmental timeline. Without an accurate date, it’s yet another old fossil. Or any other old rock.

Geochronologists will be the boffins whom learn how to find the responses to questions that are such. Geochronology is really a fiendishly complex subdiscipline of geology that relies upon a deep comprehension of both geology and geography—and of physics, chemistry, soil technology, mathematics, and computer technology. Locked even as we each is inside our span of three-score years and 10, we can not think realistically about a million several years of time, not to mention a billion years.

Geochronologists routinely handle time spans within the an incredible number of years. It is how they see world and how they think. Among the most accomplished geochronologists on earth will be the experts at the Berkeley Geochronology Center (BGC), a completely independent nonprofit institution positioned just from the campus associated with the University of Ca. They’re the people who established those times noted above. Read more…
