The Aussies have got us beat as far as footprints go. In area that has 21 different identified dinosaur tracks they have discovered the world’s largest – 1.7 meters across. If one of those beasties stood on me lying down it would just about cover me completely.
University of Queensland: ‘Australia’s Jurassic Park’ the world’s most diverse
An unprecedented 21 different types of dinosaur tracks have been identified on a 25-kilometre stretch of the Dampier Peninsula coastline dubbed “Australia’s Jurassic Park”.
A team of palaeontologists from The University of Queensland… unveil the most diverse assemblage of dinosaur tracks in the world in 127 to 140 million-year-old rocks in the remote Kimberley region of Western Australia.
Lead author Dr Steve Salisbury said the diversity of the tracks around Walmadany (James Price Point) was globally unparalleled…
“It is extremely significant, forming the primary record of non-avian dinosaurs in the western half the continent and providing the only glimpse of Australia’s dinosaur fauna during the first half of the Early Cretaceous Period,” Dr Salisbury said.
“There are thousands of tracks around Walmadany. Of these, 150 can confidently be assigned to 21 specific track types, representing four main groups of dinosaurs, ” Dr Salisbury said.
“There were five different types of predatory dinosaur tracks, at least six types of tracks from long-necked herbivorous sauropods, four types of tracks from two-legged herbivorous ornithopods, and six types of tracks from armoured dinosaurs.
“Among the tracks is the only confirmed evidence for stegosaurs in Australia. There are also some of the largest dinosaur tracks ever recorded. Some of the sauropod tracks are around 1.7 m long.”
I bet it wasn’t as fast as our Phar Lap.
They are presumably guessing at the overall size and shape but that’s a big print. And I guess rock doesn’t shrink over 130 million years.
