In Brisbane, the capital of Queensland, researchers have made a sensational paleontological discovery — a dinosaur footprint approximately 230 million years old, which has become the oldest confirmed evidence of dinosaurs existing in Australia. The uniqueness of this event is further highlighted by the fact that the footprint was found in a major city, which is an exceptional case for such discoveries.

Details of the Discovery and Scientific Analysis
A team of scientists from the University of Queensland, led by Dr. Anthony Romilio, conducted an in-depth analysis of the discovered footprint. The research confirmed that the footprint was left by a small bipedal dinosaur belonging to the early sauropodomorphs — a group from which the well-known giant long-necked dinosaurs later evolved. The footprint measures 18.5 centimeters in length, and the size of the animal is estimated to have reached 75–80 centimeters at the hips, weighing around 140 kilograms. It is likely that the dinosaur was moving along a waterway, leaving tracks in the moist soil that later fossilized.
The History of the Discovery and Its Scientific Significance
This footprint was first discovered in 1958 by a teenager named Bruce Rannegar in the Petrie Quarry, located in the Albion area. The find remained without thorough scientific investigation for over 60 years: Rannegar, who later became a paleontologist, primarily used it for educational purposes, unaware of its exceptional value. Only through collaboration with Dr. Anthony Romilio was a detailed analysis conducted, after which the footprint was officially recognized as unique. The artifact is now housed in the Queensland Museum and will be part of scientific research and museum exhibitions.
Scientists emphasize that this discovery not only changes the understanding of the early history of dinosaurs in Australia but also demonstrates that significant discoveries can remain unnoticed for years — even within modern metropolises.
