A remarkable discovery has been made, shedding light on a long-forgotten piece of history. An ancient dinosaur footprint, believed to be over 230 million years old, has been identified after more than six decades of being overlooked.
In the Brisbane suburb of Albion, a once-thriving sandstone quarry held secrets waiting to be unveiled. This is where a young Bruce Runnegar, an esteemed palaeontologist, embarked on his first fossil-hunting adventure with his grandfather. Little did he know that this very spot would yield a treasure that would span his entire career.
"As a high school student at Brisbane Grammar School, my friends and I stumbled upon this fossil during our senior year. It's been a cherished part of my personal collection ever since," Professor Runnegar reminisced.
For over six decades, the fossilized footprint traveled with Professor Runnegar, serving as a teaching tool for students across the globe. "I've always believed in the power of tangible fossils to enhance learning. They bring history to life!" he explained.
But here's where it gets intriguing... In 2021, Professor Runnegar reached out to Dr. Anthony Romilio, a fellow palaeontologist at the University of Queensland's dinosaur lab, to verify the identity of this mysterious specimen.
"When I learned that Bruce had collected this during his teenage years and carried it with him throughout his career, I wasn't surprised by its longevity. It's a true testament to the passion and dedication of palaeontologists," Dr. Romilio shared.
Using specialized software, Dr. Romilio created a 3D map of the fossil, which helped determine the type of dinosaur it belonged to. "I could tell right away that we had something special. The features were distinct, and I was thrilled!" he exclaimed.
Together, Professor Runnegar and Dr. Romilio concluded that the footprint belonged to a sauropodomorph, a type of dinosaur with a long neck, similar to a brachiosaurus, but from an earlier era. "It walked on two hind legs and was an ancestral form of these majestic creatures," Dr. Romilio explained.
The paper they released today also revealed that this dinosaur, which roamed Brisbane during the Carnian period, weighed around 144 kilograms and could run at speeds of up to 60 kilometers per hour. "It's a puzzle piece that fits into Australia's geological history, potentially making it the oldest trace fossil in the country," Dr. Romilio added.
And this is the part most people miss... Last year, Professor Runnegar donated the fossil to the Queensland Museum, where it will now be part of the University of Queensland's collection for research and education. "There's still so much to uncover about dinosaurs in Queensland. It's an exciting time for palaeontology!" said Kristen Spring, the Senior Collection Manager of Geosciences at the Queensland Museum.
Professor Runnegar, now 85, reflected on his unexpected journey into palaeontology. "I almost missed out on this career! I was told I needed a robust physique and a love for the outdoors, which I lacked. But here I am!"
Despite the development of the quarry site, Professor Runnegar believes there are more fossils waiting to be discovered in Brisbane. "There's undoubtedly more to uncover. Who knows what other secrets the sandstone buildings across the city might hold?"
Dr. Romilio shared his curiosity, mentioning the General Post Office in the CBD, made from the same sandstone material. "I often wonder if there are more dinosaur footprints hidden within its walls. It's a palaeontologist's dream!"
This discovery not only adds to our understanding of Australia's geological past but also highlights the importance of preserving and studying these ancient traces. What other mysteries are waiting to be unveiled? The world of palaeontology is full of surprises, and this is just the beginning!
