Scientists Launch AI App to Identify Dinosaurs from Footprints

Scientists launched DinoTracker, an AI app that identifies dinosaur footprints with about 90% expert-level accuracy.
Researchers trained the system using 2,000 unlabelled footprint silhouettes to avoid human classification errors.
The AI compares eight shape features, including toe spread, heel position, and ground contact.
The team published the study in Proceedings of the National Academy of Sciences.
Researchers from University of Edinburgh and Helmholtz-Zentrum developed the tool.
The system supports earlier findings that some ancient tracks appear birdlike.
Scientists caution the tracks likely came from birdlike dinosaurs, not true birds.
