Revisiting the Lark Quarry dinosaur stampede

Student Anthony Romilio may have turned a well established dinosaur stampede theory on its head.

Lark Quarry in Australia is the site of a large number of fossilized dinosaur footprints dating back 95 million years. The accepted explanation for what happened at this location is that a group of dinosaurs drinking from a water hole were startled and fled when a large predatory dinosaur arrived on the scene. Palaeontology student Anthony Romilio however has cast serious doubt on whether this is in fact what actually took place.

The footprints, he argues, do not conform to what would be expected of a stampeding herd. Instead, the light and far-spaced prints suggest that the dinosaurs could have been swimming in shallow water with their feet just touching the mud underneath.

"It's billed as the world's only known example of a dinosaur stampede - but new research is challenging the established version of events at Lark Quarry, in the Australian outback, almost 100 million years ago."

There are other elements that could cause a stampede ... how about wildfire? The varied footprint depths could be explained as flying dinosaurs getting a running start so as to take off. And, the fire would have hardened the mud much as a kiln and preserved the footprints.
