A dinosaur fossil footprint found about 50 years ago is from a plant-eating dinosaur -- not a huge meat-eating dinosaur as previously thought, according to a new study.
The footprint, which dates back to the Triassic Period about 220 million years ago, was initially thought to have come from a large dinosaur from the Eubrontes family, said lead study author Anthony Romilio, a technical assistant in the School of Chemistry and Molecular Biosciences at the University of Queensland in Australia, in a statement. He worked with a team of international researchers to reanalyze the fossil and found the footprint belonged to the Prosauropod, an herbivorous dinosaur.
Predatory dinosaurs had toes that were bunched together, but the fossil's toes were spread apart. Tiny crab preserved in 100-million-year-old amber lived among dinosaursThis long-necked animal had legs around 4.5 feet tall and was nearly 20 feet in length. The dinosaur likely had a small head and walked on two feet, Romilio added.
