Evidence of herd behavior in dinosaurs found
A vast trove of fossils unearthed in Argentina’s southern Patagonia region is offering the oldest-known evidence that some dinosaurs thrived in a complex and well-organized herd structure, with adults caring for the young and sharing a communal nesting ground.
Scientists said on Oct. 21 the fossils include more than 100 dinosaur eggs and the bones of about 80 juveniles and adults of a Jurassic Period plant-eating species called Mussaurus patagonicus, including 20 remarkably complete skeletons. The animals experienced a mass-death event, probably caused by a drought, and their bodies were subsequently buried by wind-blown dust, the researchers said. (Reuters)
Vikings crossed the Atlantic 1,000 years ago
Long before Columbus crossed the Atlantic, eight timber-framed buildings covered in sod stood on a terrace above a peat bog and stream at the northern tip of Canada’s island of Newfoundland, evidence that the Vikings reached the New World first.
But precisely when the Vikings journeyed to establish the L’Anse aux Meadows settlement had remained unclear until now. Scientists on Oct. 20 said a new type of dating technique using a long-ago solar storm as a reference point revealed that the settlement was occupied in A.D. 1021, exactly a millennium ago and 471 years before the first voyage of Columbus.
