Scientists later found that signs of this collision seemed evident near the town of Chicxulub (CHEEK-sheh-loob) in Mexico in the form of a gargantuan crater more than 110 miles (180 kilometers) wide.The explosion, likely caused by an object about 6 miles (10 km) across, would have released as much energy as 100 trillion tons of TNT, more than a billion times more than the atom bombs that destroyed Hiroshima and Nagasaki."We have shown that these events are synchronous to within a gnat's eyebrow, and therefore, the impact clearly played a major role in extinctions, but it probably wasn't just the impact." The new extinction date is precise to within 11,000 years."When I got started in the field, the error bars on these events were plus or minus a million years," added paleontologist William Clemens at the University of California at Berkeley, who did not participate in this research.The only survivors among the dinosaurs are the birds.

Choi is a contributing writer for Live Science and "These precursory phenomena made the global ecosystem much more sensitive to even relatively small triggers, so that what otherwise might have been a fairly minor effect shifted the ecosystem into a new state," Renne said. "What we really need to do is to understand better what was going on before the impact — what was the level of ecological stress that existed that allowed the impact to be the straw that broke the camel's back? "We also need better dates for the massive volcanism at the Deccan Flats to better understand when it first started and how fast it occurred." The scientists detailed their findings in the Feb. He covers all things human origins and astronomy as well as physics, animals and general science topics.
