The mine has long since closed, but fortunately, in 1964, geologists and the Queensland Museum mapped the trackway and made plaster casts, now used in current research.
“After millions of years, the plant material turned into coal which was extracted by the miners to reveal a ceiling of siltstone and sandstone, complete with the natural casts of dinosaur footprints.” “This explains why today they occur in an upside-down position right above our heads,” Mr Klein said. Hendrik Klein, co-author and fossil expert from Saurierwelt Paläontologisches Museum in Germany, said the footprints – referred to as ‘Evazoum’, scientifically, the footprint type made by prosauropod dinosaurs – were made on the water-sodden layers of ancient plant debris with the tracks later in-filled by silt and sand. “It must have been quite a sight for the first miners in the 1960s to see big bird-like footprints jutting down from the ceiling,” Dr Romilio said. The dinosaur fossils were discovered more than half a century ago around 200 metres deep underground at an Ipswich coal mine, just west of Brisbane. “Unfortunately, most earlier researchers could not directly access the footprint specimen for their study, instead relying on old drawings and photographs that lacked detail,” Dr Romilio said. The research team suspected there was something not-quite-right with the original size estimates and there was a good reason for their doubts. However, findings made by a team of international researchers, published today in the peer-reviewed journal Historical Biology, in fact shows the tracks were instead made by a dinosaur known as a Prosauropod – a vegetarian dinosaur that were smaller, with legs about 1.4 metres tall and a body length of six metres. “This idea caused a sensation decades ago because no other meat-eating dinosaur in the world approached that size during the Triassic period.” “For years it’s been believed that these tracks were made by a massive theropod predator that was part of the dinosaur family Eubrontes, with legs over two metres tall,” Dr Romilio said. University of Queensland palaeontologist Dr Anthony Romilio recently led an international team to re-analyse the footprints, dated to the latter part of the Triassic Period, around 220 million-year-ago.
