Scientists launched DinoTracker, an AI app that identifies dinosaur footprints with about 90% agreement with human experts.
Researchers trained the system using 2,000 unlabelled footprints to avoid errors from disputed classifications.
The AI compares eight shape features, including toe spread and heel position, to group similar tracks.
The study, published in Proceedings of the National Academy of Sciences, involved scientists from the University of Edinburgh and Helmholtz-Zentrum.
Steve Brusatte said the tool confirms that some ancient tracks appear birdlike but likely came from dinosaur ancestors.
Independent experts warned ground conditions may still influence results, requiring human verification.
