Scientists have launched an AI-powered app called DinoTracker to identify dinosaurs from fossil footprints.
The system analyzes footprint shapes without relying on prior labels.
Researchers fed the model 2,000 unlabelled footprint silhouettes.
The AI grouped prints using eight key shape features.
It matched expert classifications about 90% of the time.
The study was led by researchers from University of Edinburgh and Helmholtz-Zentrum.
The findings were published in Proceedings of the National Academy of Sciences.
Some results support earlier claims of birdlike dinosaur tracks.
Scientists say more evidence is needed before rewriting bird evolution history.
