Dinosaur tracks found in Australia have revealed new clues pointing to a prehistoric river crossing.
At a site called Lark Quarry as many as 4,000 fossilized dinosaur tracks are preserved in an area the size of a basketball court. The huge number of prints was thought to be the result of a stampede, but now researchers believe that the tracks could have actually been made at a location used by large numbers of dinosaurs to cross a river.
"There are certainly some footprints there that I've seen that are consistent with a small dinosaur that is swimming and it can't quite touch the bottom with its toes, but it still looks like we are talking about a significant group of dinosaurs all moving together as one mob," said paleontologist Paul Willis.
Fossilized track marks from a stampede of dinosaurs in Australia actually may have come from swimming animals, new research suggests. The finding, published in the January issue of the Journal of Vertebrate Paleontology, upends the traditional interpretation of the world's only dinosaur stampede.
