Scientists launched DinoTracker, an AI app that identifies dinosaurs from ancient footprints with about 90% expert-level accuracy.
Researchers from University of Edinburgh trained the system using 2,000 unlabeled footprint silhouettes.
The AI groups prints by shared shape features, including toe spread, heel position, and ground contact.
Users can upload footprints, compare similar tracks, and test how shape changes affect results.
The team reported findings in Proceedings of the National Academy of Sciences.
Results support earlier observations that some ancient tracks look strikingly birdlike.
Scientists caution the tracks likely came from birdlike dinosaurs, not true early birds.
