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.
Instead
of a group of small dinosaurs trying to escape a massive carnivore, the fossils
may reveal an ancient dinosaur "superhighway" or river crossing, said
study co-author Anthony Romilio, a paleontologist at the University of
Queensland in Australia.
