Palaeontologists in Peru on Monday unveiled the 9-million-year-old fossil of a relative of the great white shark that once inhabited the waters of the southern Pacific Ocean, where it liked to devour sardines. The nearly-complete Cosmopolitodus Hastalis fossil was found some 235 km (146 miles) south of Lima in Peru's Pisco basin, a hot, desert area famed for frequent discoveries of ancient marine species. The shark is believed to be an ancestor of the great white shark. It is now extinct, but its teeth once spanned up to 8.9 cm (3.5 inches) in length, while adults could grow to near seven meters in length - the size of a small boat.

Later, after the truck driver dumped the load, a dozer driver was ready to flatten the dirt but stopped for a closer look when he, too, spotted that bit of white. Only then did the miners realize they had unearthed something special: a 7-foot-long mammoth tusk that had been buried for thousands of years. “We were very fortunate, lucky to find what we found,” said David Straley, an executive of North American Coal, which owns the mine. In this image provided by Coleman Fredricks, coal miners unearthed a mammoth tusk in May 2023 at the Freedom Mine near Beulah, N.D. The large scoop of an electric shovel du...

New species of stegosaur is oldest discovered in Asia, and possibly the world Bashanosaurus primitivus roamed the earth around 168 million years ago during the Middle Jurassic period, suggesting that stegosaurs may have originated in Asia Bashanosaurus primitivus - the newest and oldest species of stegosaur in Asia. Illustration: Banana Art Studio Relatively small, but fearsome-looking stegosaur measured about 2.8 metres (9 feet) from nose to tail—but scientists can’t tell whether the remains are those of an adult or juvenile. A new species of one of the most recognisable types of dinosaur is the oldest stegosaur ever found in Asia, and one of the earliest unearthed anywhere in the world, according to research published in the peer-reviewed Journal of Vertebrate Paleontology. ...
