Ancient footprints believed to be made by a vicious dinosaur predator were exposed by synthetic intelligence to in truth be from a timid herbivore.
University of Queensland paleontologist Dr. Anthony Romilio, in an international collaboration, used AI pattern acknowledgment to re-analyze footprints from the Dinosaur Stampede National Monument, southwest of Winton in Central Queensland.
” Large dinosaur footprints were very first found back in the 1970s at a track site called the Dinosaur Stampede National Monument, and for lots of years they were believed to be left by a predatory dinosaur, like Australovenator, with legs almost two meters long,” stated Dr. Romilio.
” The strange tracks were thought to be left during the mid-Cretaceous Period, around 93 million years ago.
” But working out what dino types made the footprints precisely– especially from 10s of millions of years ago– can be a quite tough and complicated service.
” Particularly since these big tracks are surrounded by countless small dinosaur footprints, leading numerous to believe that this predatory monster could have sparked a stampede of smaller dinosaurs.
” So, to split the case, we decided to use an AI program called Deep Convolutional Neural Networks.”
The deep knowing neural network was trained with 1,500 dinosaur footprints, all of which were theropod or ornithopod in origin. These are the groups of dinosaurs appropriate to the Dinosaur Stampede National Monument prints.
The results were clear: the tracks had actually been made by a herbivorous ornithopod dinosaur.
Dr. Jens Lallensack, lead author from Liverpool John Moores University in the UK, stated that the computer assistance was vital, as the group was initially at an impasse.
” We were pretty stuck, so thank god for modern innovation,” Dr. Lallensack stated. “In our research study team of 3, a single person was pro-meat-eater, one individual was unsure, and one was pro-plant-eater.
” So– to truly examine our science– we decided to go to five experts for information, plus usage AI.
” The AI was the clear winner, outshining all of the experts by a large margin, with a margin of error of around 11 percent.
” When we utilized the AI on the large tracks from the Dinosaur Stampede National Monument, all but one of these tracks was confidently classified as left by an ornithopod dinosaur– our prehistoric predator.”.
The team hopes to continue to add to the fossil dinosaur tracks database and perform additional AI examinations..
The research is published in the Journal of the Royal Society Interface and consists of cooperations between Australian, German, and UK researchers..
A reproduction of the dinosaur trackway is on display screen at the Queensland Museum, Brisbane, and the track site can be gone to near southwest of Winton, Queensland.
