Unbeknownst to paleontologists, the slab of rock had been sitting in a high school for decades.
Using a cast, 3D imaging, and light filters, Romilio documented 66 footprints on the boulders surface.
The boulder was first discovered at a coal mine near Biloela, Central Queensland, two decades ago.

Significant fossils like this can sit unnoticed for years, even in plain sight, Romilio explained.
Its incredible to think that a piece of history this rich was resting in a schoolyard all this time.
The specimen preserves two distinct footprints belonging to a larger two-legged dinosaur.
