Scientists have created an AI-powered app called DinoTracker, which uses artificial intelligence to identify dinosaur footprints based on their unique characteristics. The innovative tool analyzes the shape and features of footprint silhouettes to determine how similar or different they are from one another.
A team of researchers, led by Prof Steve Brusatte from the University of Edinburgh, fed 2,000 unlabelled footprint silhouettes into the AI system, which was trained on a range of meaningful features such as toe spread, ground contact, and heel position. The resulting eight features revealed variations in the footprints' shapes that experts had previously overlooked.
Using DinoTracker, users can upload the silhouette of a footprint, explore seven other similar footprints, and manipulate the footprint to see how changing its characteristics affects which other footprints are deemed most similar. This allows for a more accurate identification of dinosaur species based on their tracks.
One notable finding is that the AI system supported the theory that certain bird-like footprints from the Triassic period show remarkable similarities with those of modern birds, such as Archaeopteryx. According to Prof Brusatte, this suggests that birds have an even deeper ancestry than previously thought, dating back tens of millions of years.
However, the researchers caution that their findings do not necessarily prove the existence of early bird species. Instead, it is likely that these tracks were made by meat-eating dinosaurs with bird-like feet. Dr Jens Lallensack from Humboldt University of Berlin noted that a key limitation of the system was that its features of interest were based on the way the foot sank into soft ground, rather than its actual shape.
Despite this limitation, DinoTracker represents an exciting step forward in using AI to analyze and understand dinosaur tracks. As Dr Hartmann from Helmholtz-Zentrum Germany said, "You never find a footprint without knowing which dinosaur made it," but with the help of machines like DinoTracker, researchers can make more accurate connections between footprints and their corresponding species.

This AI-powered app DinoTracker is giving me LIFE! I mean, can you even imagine being able to track down (pun intended) the exact dinosaur that made those epic footprints? 
It's like something out of a sci-fi movie. And the fact that it's using AI to analyze all these tiny features that we never thought were important before is just mind-blowing! 
I mean, who knew toe spread and heel position could be so telling? 
That's some serious dinosaur drama right there! 
But at the same time, I'm also a bit skeptical about the limitations of this system. Like, if you're using it on soft ground, how accurate is that going to be? 
Still, it's all part of the excitement of scientific discovery, right? 
. I mean, who wouldn't want to know what kind of dino made a certain footprint, right? But for real though, the fact that it's analyzing toe spread, ground contact, and heel position shows just how much we can learn from these ancient tracks. And finding similarities between bird-like footprints from the Triassic period with modern birds is wild 
.
] AI is like, totally uncovering dino secrets! 
]
] Eight features that helped unlock ancient dino mysteries? 
] Birds and dinos: the ultimate party crashers of history 
. I was reading this article about DinoTracker and it's like, wow! The fact that the researchers were able to analyze 2,000 unlabelled footprint silhouettes and come up with eight meaningful features is just insane 
. Anyway, this app is like, totally game-changing for paleontology and AI enthusiasts alike 
.
. but at the same time, i gotta wonder what other secrets are hidden in those tracks that we're not even thinkin about yet 
. anyway, this is a cool step forward for sci & tech, let's keep pushin boundaries! 
. Can't wait to see what other cool discoveries come out of it! 
. And don't even get me started on the fact that it's only analyzing the shape of the footprint in relation 2 how it sank into the ground. What about the actual shape? That's probly where all the real info is hidin' 
.
! The fact that it can analyze footprint silhouettes to determine dinosaur species is crazy 
. It's not just about finding tracks and saying "oh, that's a T-Rex" 
.
Anyway, still super cool and can't wait for more AI-powered discoveries!
That's not exactly a cutting-edge feature.
. I mean, I guess it's cool for the paleo crowd or whatever, but for the rest of us, can we just stick to our Netflix shows? 
this is amazing! i mean think about it we've been studying dinosaurs for ages and they were able to come up with an app that actually makes sense with all these tracks i feel so proud of the scientists who worked on this project they're like true detectives of the ancient world lol imagine being able to figure out what kind of bird had those awesome wings 
from 150 million years ago its just wild
