For twenty years, a stone slab tried in a Queensland school office, ignored by all. However, below its rough surface hides an unsuspected paleontological treasure: 66 fingerprints of dinosaurs, perfectly preserved, old 200 million years. Extract from a neighboring mine in 2002, this block revealed its secret only after a fortuitous rediscovery. Such a piece, witness to a bygone era, has she gone unnoticed for so long?
A forgotten block for 20 years
For more than two decades, a stone slab of one square meter remained in a corner of the main office of the secondary school in Biloela, Queensland, without attracting attention. Nothing distinguished it from a simple rock, until local observations arouse the interest of paleontologists. However, this block contains one of the strongest concentrations of fingerprints of dinosaurs ever recorded in Australia.
Its history begins in 2002, when it was extracted from the Callide mine, located about fifteen kilometers from the school. The geologist Wes Nichols, then stationed in the region, discovers this unusual rock and decides to give it to the establishment where his wife taught. Without in -depth study or particular development, the slab is placed in the school and its extraordinary origin goes unnoticed.
It is only recently that residents intrigued by the presence of stone contacted Anthony Romilio, paleontologist at the University of Queensland, specialist in fingerprints of dinosaurs. By examining the slab, the researcher quickly understood the extent of the discovery. His analysis revealed the presence of 66 fossilized fingerprints dating from around 200 million years, left by at least 47 distinct dinosaurs belonging to the genus Anomoepus, a small bipedal herbivore from the lower Jurassic. A detailed study of these traces was published in the scientific journal Historical Biology, confirming their importance for understanding Australian prehistorian fauna.
The Biloela region is not at its first paleontological discovery. For several decades, similar imprints have been identified in Carnarvon Gorge, Mount Morgan and Callide. But so far, no bone fossil of Anomoepus has been found in Australia, making these imprints crucial proof of their presence on the continent.
A scientific treasure before our eyes
The unusual concentration of fingerprints on such a small surface intrigues researchers. The slab has 13 distinct tracks. These traces were left by animals advancing in different directions. According to the Romilio team, they come from a river environment. The imprints would have formed on mud benches covered with shallow water. Their preservation state indicates a gradual deposit of sediment. This phenomenon would have imprisoned traces before they disappear under the effect of erosion or other natural factors.
These imprints are attributed to Anomoepus Scambus, a small ornithischian. These dinosaurs, little known to the general public, had long posterior members and short arms. Their body was stocky and their two -place displacement. The rock reveals well -marked fingerprints with three fingers. Certain clues, such as the orientation and the arrangement of the tracks, intrigue researchers. These elements suggest possible gregarious behavior. These animals may therefore move in a group.
Romilio and his team used 3D modeling to analyze these fingerprints. They took pictures from several angles, then adjusted the brightness and the contrast. This technique revealed details invisible to the naked eye, such as the depth of the brands and the subtle reliefs. Already used on other Australian sites, it has notably identified fossilized fingerprints in Mount Morgan.
This is not the first time that a major paleontological discovery has been ignored for years. Another rocky block, also from the callide mine, served as a simple delimitation for parking before being identified as containing two fossilized footprints.
What will become of this discovery of fingerprints of dinosaurs?
Faced with the scientific interest of this slab, local authorities have decided to give it a place of choice. According to The Guardian, she will be exhibited in the offices of the Banana Shire municipal council. The public will thus be able to admire it and discover its history. Mayor Nev Ferrier underlines that this discovery recalls the geological richness of the region. It also highlights its key role in the study of Australian dinosaurs.
The study published in Historical Biology insists on the uniqueness of these imprints. They are among the rare direct evidence of herbivorous dinosaurs in Australia at that time. Without bone fossils, these traces deliver precious clues to the abundance and way of life of anomoepus. The Biloela region could conceal other vestiges, buried under sediments or forgotten in private and museum collections.
Romilio therefore hopes that this discovery will encourage other fossil reports. He recalls that the majority of paleontological finds in Australia are not made by scientists, but by enthusiasts or inhabitants falling by chance on unusual rocks. Each report can lead to a new scientific advance, and perhaps, to discover a first complete skeleton of Anomoepus in Australia.
