Could the footprints of giant sauropod dinosaurs have created quicksand "death pits" that doomed many smaller species ?
Unusual pits containing the fossil remains of dozens of small dinosaur species have prompted a lot of speculation among scientists. One new study has suggested that these pits are formed by large sauropod dinosaurs walking through volcanic ash and creating footprints that then filled with a quicksand-like substance. Smaller dinosaurs would later get stuck in the quicksand and perish there resulting in a death trap that can accumulate dozens of corpses.
Following in a giant dinosaur's footsteps could be fatalóbut not for the reasons you might suspect. Mysterious "death pits" holding the fossil skeletons of nearly two dozen small dinosaur species may actually be the 160-million-year-old footprints of an ancient behemoth, a new study suggests.
