Scientists launched DinoTracker, an AI app that identifies dinosaurs from fossil footprints with about 90% agreement with human experts.
Researchers from University of Edinburgh and Helmholtz-Zentrum trained the system using 2,000 unlabelled footprint silhouettes.
The AI groups prints by shared shape features rather than relying on potentially flawed human labels.
The team reported the findings in Proceedings of the National Academy of Sciences.
Steve Brusatte said the results support long-standing observations of birdlike dinosaur tracks.
Other experts caution that footprint shapes may reflect ground conditions rather than true bird ancestry.
