Researchers in Brazil reported their discovery of a new marine crocodile species on Wednesday, showing that the reptiles survived the mass extinction of dinosaurs 65 million years ago.In the report published in the Proceedings of Royal Society B research journal, paleontologists said they found the new dyrosaurid crocdylomorph in the Poty Quarry, a limestone quarry located close to Recife in northeastern Brazil. Researchers suggested that the Guarinisuchus munizi survived the...

Leaping, furry mini-monkeys that were as small as mice crossed the Bering land bridge long before humans, representing North America's oldest known primates. This new claim is based on the fossils of at least three individuals of this previously unknown species of extinct primate uncovered at a site near Meridian, Miss., scientists announced today. The researcher estimates the primate fossils date to about 55.8 million years ago. If the age of the fossils is accurate, the new...

With implications for present climate, new data links past spike in temperature with increased voraciousness of plant-eating insectsMore than 55 million years ago, the Earth experienced a rapid jump in global carbon dioxide levels that raised temperatures across the planet. Now, researchers studying plants from that time have found that the rising temperatures may have boosted the foraging of insects. As modern temperatures continue to rise, the researchers believe the planet could see...

The recovery of biodiversity after the end-Cretaceous mass extinction was much more chaotic than previously thought, according to paleontologists. New fossil evidence shows that at certain times and places, plant and insect diversity were severely out of balance, not linked as they are today. The extinction took place 65.5 million years ago. Labeled the K-T extinction, it marks the beginning of the Cenozoic Era and the Paleocene Epoch. "The K-T caused major extinction among North American...

WASHINGTON (AP) - An increase in the planet's temperature 55 million years ago prompted major shifts in plant distribution, researchers reported Thursday. A study of plant fossils from the Bighorn Basin in Wyoming shows the arrival of plants from warm southern areas, displacing those that had been growing there previously, according to a research team led by Scott L. Wing, chairman of the Department of Paleobiology at the Smithsonian's National Museum of Natural History. Their findings are...
