"Previous research had suggested that the maniraptorans were around in the Middle Jurassic, but the actual fossil evidence was patchy and disputed. Along with fossils found elsewhere, this research suggests the group had already achieved global distribution by this time," said Simon Wills, a Ph.D. student at the Natural History Museum who led the research.
"The teeth we analyzed include what are currently the only troodontid and therizinosaur fossils ever recorded from the UK and are the oldest evidence of these dinosaurs anywhere in the world," he added.Therizinosaur, a sizable herbivorous dinosaur from the late Cretaceous, was distinguished by its long claw bones that resembled scissor blades. These prehistoric species were included in the most recent Jurassic World movie because of its distinctive appearance.
While earlier research has attempted to categorize isolated teeth using several statistical techniques, it hasn't always succeeded. The current study's authors have been trying to enhance this after demonstrating that machine-learning models can recognize isolated teeth from known species with high accuracy.
"The use of machine learning in vertebrate paleontology is still in its infancy, although its usage is growing," Simon says. "The main drawback is the need for a comprehensive training dataset for the models to learn from. In our study we are fortunate that there is already a relatively large dataset of dinosaur tooth measurements available that we could use to train the models," Simon adds.
