The Cinderella problem
Scientists have compared the process of identifying a dinosaur from its footprint to the story of Cinderella and trying to find the right foot for the glass slipper. However, the matter is much more complex, as footprint shapes change based on soil type and animal movement. Traditional methods relied on human classifications that can be inaccurate.
The smart solution: Unsupervised learning
The team fed the system thousands of footprint images without prior classification, leaving the artificial intelligence to find patterns. The system successfully identified precise features and grouped footprints with an accuracy matching experts by 90%, while also revealing new overlaps that went previously unnoticed.
Exciting discoveries about birds
The analysis showed that some very old footprints (from the Triassic period) look strikingly similar to bird tracks, despite being much older than the first known appearance of birds. This raises new hypotheses: either birds appeared much earlier than we think, or certain dinosaurs evolved bird-like feet independently.
App features for the public
The app is available for free and allows users to upload photos of tracks they find to compare them with the database. This turns smartphones into powerful scientific tools in everyone’s hands, which could accelerate the pace of new discoveries.
Limitations of the technology
Despite the system’s accuracy, scientists warn that footprints remain an incomplete record affected by erosion and time, meaning the results offer strong probabilities rather than definitive, conclusive answers.
Frequently asked questions
Q: Is the app free?
A: Yes, it is available for free download and use.
Q: How does artificial intelligence help here?
A: It analyzes the geometric shapes of footprints with an accuracy and speed surpassing human capability, comparing them against thousands of samples.
Q: Does this mean history books will change?
A: The results raise strong questions that could lead to adjustments in our understanding of bird evolution, but they require further physical evidence (bones) for confirmation.
