A new study theorizes that the dinosaurs were wiped out 65 million years ago by at least two meteorite strikes rather than one. Scientists previously thought that a huge meteorite impact occurred in the Gulf of Mexico, wiping out the dinosaurs in one fell swoop. New evidence, however, suggests that a second impact occurred in the Ukraine, according to a BBC News report on Friday. The study findings were published in the journal Geology by a team lead by Professor David Jolley of Aberdeen...

For decades, scientists have accumulated ever-larger datasets that suggest an enormous space rock crashed into the ocean off the Yucatan Peninsula more than 65 million years ago, resulting in the Cretaceous-Paleogene (K-Pg) extinction. Recent research, supported in part by the National Science Foundation (NSF), suggested that the impact could have occurred 300,000 years prior to the K-Pg extinction, and that another cause--perhaps a second impact, or the long-lasting volcanic activity at the...

Impact didn't lead to mass extinction 65 million years ago, geologists find The enduringly popular theory that the Chicxulub crater holds the clue to the demise of the dinosaurs, along with some 65 percent of all species 65 million years ago, is challenged in a paper to be published in the Journal of the Geological Society on April 27, 2009. The crater, discovered in 1978 in northern Yucutan and measuring about 180 kilometers (112 miles) in diameter, records a massive extra-terrestrial...

AUSTIN, Texas -- The most detailed three-dimensional seismic images yet of the Chicxulub crater, a mostly submerged and buried impact crater on the Mexico coast, may modify a theory explaining the extinction of 70 percent of life on Earth 65 million years ago.The Chicxulub crater was formed when an asteroid struck on the coast of the Yucatan Peninsula. Most scientists agree the impact played a major role in the "KT Extinction Event" that caused the extinction of most life on Earth, including...

There's growing evidence that the dinosaurs and most their contemporaries were not wiped out by the famed Chicxulub meteor impact, according to a paleontologist who says multiple meteor impacts, massive volcanism in India, and climate changes culminated in the end of the Cretaceous Period. The Chicxulub impact may, in fact, have been the lesser and earlier of a series of meteors and volcanic eruptions that pounded life on Earth for more than 500,000 years, say Princeton University...

MEXICO CITY (AP) -- Scientists working off the Yucatan Peninsula are preparing to use sound waves to search for information about an asteroid that may have wiped out the dinosaurs 65 million years ago. But environmental activists are trying to shut the project down, saying the technology could harm whales, sea turtles and several varieties of fish that provide a livelihood for thousands of Mexicans along the gulf coast. Marine seismologists from the University of Texas Institute of...
