Scientists launched an AI app called DinoTracker to identify dinosaurs from fossil footprints.
Researchers from University of Edinburgh and Helmholtz-Zentrum developed the system.
The AI analyses footprint shapes without relying on potentially incorrect expert labels.
It learned from 2,000 unlabelled footprint silhouettes and identified eight key shape features.
The system matches human expert classifications about 90% of the time.
The team reported the findings in Proceedings of the National Academy of Sciences.
Results support earlier claims that some dinosaur tracks appear strikingly birdlike.
However, researchers say meat-eating dinosaurs likely made these tracks, not early birds.
