Dinosaur fossil from a supposed huge carnivore actually belongs to something else - CNN

This would make the footprint the only physical evidence of any Triassic-age Prosauropod in Australia, Romilio said.

The fossil was discovered in a coal mine in Ipswich, a city west of Brisbane, nearly 656 feet (200 meters) underground.

Scientists at the time estimated the creature that made the footprint to have legs over 6 feet (2 meters) tall, which would have made it the largest carnivorous dinosaur of the Triassic period, he said.

Romilio wasn't buying it -- in part because of a lack of consistent data regarding the fossil.

"I knew about this fossil many years ago and was surprised there was no consensus on basic details such as the footprint length or even its shape," he said.

One indication the footprint came from an herbivore like Prosauropod was the shape of the feet, Romilio said.
