Source: University of Missouri In a recent study, researchers studied ancient reefs built by sponge-like creatures called archaeocyathids in Nevada, 514 million years ago. They found that early reefs did not appear to boost biodiversity in the same way as modern coral reefs do. Modern coral reefs are known as biodiversity hotspots, supporting the entire…
Dinosaurs, the colossal rulers of prehistoric Earth, were not immune to the ailments that still plague modern animals, including cancer. In a groundbreaking discovery, scientists have confirmed that a duck-billed dinosaur that lived 70 million years ago suffered from a benign tumour. The fossilised remains of Telmatosaurus Transsylvanicus, found in present-day Romania, contained evidence of…
More than 500 million years before Matt Groening and “The Simpsons” introduced us to Blinky, a mutated fish with an extra eye swimming through Springfield’s Old Fishin’ Hole, a three-eyed predator chased prey through seas of the Cambrian Period. Once it caught its quarry, a pair of spine-covered grasping claws and a circular mouth covered…
For decades, fishermen sailing off the coast of Taiwan have sometimes discovered fossils in their trawling nets: the bones of elephants, buffalo and other big mammals that lived tens of thousands of years ago, when the sea level was so low that Taiwan was linked to Asia by a land bridge. But in 2010, a…
For more than a decade, scientists have chased the idea of reviving extinct species, a process sometimes called de-extinction. Now, a company called Colossal Biosciences appears to have done it, or something close, with the dire wolf, a giant, extinct species made famous by the television series “Game of Thrones.” In 2021, a separate team…
New research painted a more accurate picture of the megafauna that spread widely around the Americas before they went extinct. Source link
Ralph Holloway, an anthropologist who pioneered the idea that changes in brain structure, and not just size, were critical in the evolution of humans, died on March 12 at his home in Manhattan. He was 90. His death was announced by Columbia University’s anthropology department, where he taught for nearly 50 years. Mr. Holloway’s contrarian…
Ten years ago, this was just a big hole in the ground behind a Lowe’s home improvement store in southern New Jersey, an unlikely place to find what might be one of the world’s most important fossil sites. But 66 million years ago, tantalizingly close in time to when the dinosaurs went extinct, a multitude…
For generations, scientists looked to the East African savanna as the birthplace of our species. But recently some researchers have put forward a different history: Homo sapiens evolved across the entire continent over the past several hundred thousand years. If this Africa-wide theory were true, then early humans must have figured out how to live…
Above the shores of prehistoric seas and lakes, pterosaurs roamed the skies. They were feathered creatures that ranged in size from pigeons to planes, and the first vertebrates known to have been able to fly. And for millions of years, they had long tails ending in a prominent flap of skin called a vane. Paleontologists…
