Incredible Discovery at Biloela State High School

In a jaw-dropping revelation, students at Biloela State High School in Queensland, Australia, unknowingly walked over a significant fossil discovery for years—66 dinosaur footprints embedded in a single rock slab! This astounding find, made by paleontologist Anthony Romilio and his team from the University of Queensland’s Dinosaur Lab, dates back to the early Jurassic period, around 200 million years ago, shedding light on dinosaurs' movements and behaviors in the region.

A Treasure Trove of Dinosaur Tracks

Initially discovered in 2002, the rock slab sat unrecognized for years, displaying one of the richest treasure troves of dinosaur tracks in the country. Containing footprints from 47 individual dinosaurs, it highlights a thriving ecosystem that once teemed with life in what we now know as the Callide Basin.

Characteristics of the Ornithischian Dinosaurs

What’s remarkable is that most of the footprints belong to small ornithischian dinosaurs—these herbivores were characterized by long legs, sturdy bodies, short arms, and beaked heads. Romilio notes that these creatures likely moved slowly at speeds under 4 mph, leaving a fascinating trail behind.

Tracking Directions and Environmental Insights

Intriguingly, the orientation of the tracks suggests that these dinosaurs were moving in one of two directions, possibly crossing a river—a notion bolstered by approximately 100 circular marks found on the slab, believed to be impressions from invertebrates and indicative of a once-lively aquatic environment.

Other Significant Discoveries

The stone slab wasn't alone in its hiding; the research team also uncovered other significant rock specimens bearing dinosaur footprints. One such slab, previously at Boundary Hill Mine, had become a decorative feature at the entrance of Callide Mine’s parking lot, exhibiting two footprints from a bipedal dinosaur measuring about 31 inches in length. Even more surprising, a third specimen was found repurposed as a bookend, containing a single well-preserved footprint, proving that exciting discoveries can often lie right under our noses.

An Essential Piece of Paleontological History

Prior to this, sites with early Jurassic dinosaur footprints in Queensland were limited to locations at Mount Morgan, Carnarvon Gorge, and Biloela, making this new find an essential piece in understanding dinosaur migration and behavior in Australia. Romilio remarked, “This discovery provides an unprecedented snapshot of dinosaur behavior in this region,” emphasizing that ornithischian dinosaurs were likely more widespread than previously thought.
