Scientists Are Using AI to Help Identify Dinosaur Footprints

The Dinotracker app was trained on eight major characteristics of dinosaur footprints to quickly determine the species.

An international team of researchers has devised a futuristic tool to examine the footprints left by dinosaurs in our ancient past. The AI-powered app, Dinotracker, can identify dinosaur footprints in moments.

The research comes from a joint project by the Helmholtz-Zentrum research center in Berlin and the University of Edinburgh in Scotland. The Proceedings of the National Academy of Sciences published the paper on Monday.

Identifying a dinosaur species from a footprint isn’t always easy. The footprint is hundreds of millions of years old, often preserved in layers of rock that have shifted over the eons since the track was laid.

Also, we still have a lot to learn about dinosaurs, and it’s not always clear which species left a footprint. Subjectivity or bias can come into play when identifying them, and scientists don’t always agree with the results.

Gregor Hartmann of Helmholtz-Zentrum, who led the project, told CNET that the research team sought to remove this propensity from the identification process by developing an algorithm that could be neutral.

«We bring a mathematical, unbiased point of view to the table to assist human experts in interpreting the data,» Hartmann said.

Researchers trained the algorithm on thousands of real fossil footprints, as well as millions of simulated versions that could recreate «natural distortions such as compression and shifting edges.»

How AI is being used on dinosaur tracks

The system was trained to focus on eight major characteristics of dinosaur footprints, including the width of the toes, the position of the heel, the surface area of the foot that contacted the ground and the weight distribution across the foot.

The AI tool uses these traits to compare new footprints to existing fossils, and then determines which dinosaur was most likely responsible for the footprint.

The team tested it against human expert classifications and found that the AI agreed with them 90% of the time.

Hartmann made it clear that the AI system is «unsupervised.»

«We do not use any labels (like bird, theropod, ornithopod) during training. The network has no idea about it,» Hartmann said. «Only after training, we compare how the network encodes the silhouettes and compare this with the human labels.»

Hartmann said that the hope is for Dinotracker to be used by paleontologists and that the AI tool’s data pool grows as it’s used by more experts.

Bird vs. dinosaur

Using Dinotracker, the researchers have already uncovered some intriguing possibilities on the evolution of birds. When analyzing footprints more than 200 million years old, the AI found strong similarities with the foot structures of extinct and modern birds.

The team says one possibility is that birds originated tens of millions of years earlier than we thought. But it’s also possible that early dinosaur feet just look remarkably like bird feet.

This evidence, Hartmann notes, isn’t enough to rethink the evolution of birds, since a skeleton is the «true evidence» of earlier bird existence.

«It is essential to keep in mind that over these millions of years, lots of different things can happen to these tracks, starting from the moisture level of the mud where it was created, over the substrate it was created on, up to erosion later,» he said. «All this can heavily change the shape of the fossilized track we find, and ultimately makes it too difficult to interpret footprints, which was the motivation for our study.»

Dinotracker is available for free on GitHub. It’s not in a download-and-use format, so you’ll have to know a bit about software to get it up and running.

Google’s Pixel 10A Is Coming to Japan With an Exclusive Blue Edition and Special Wallpaper

This model comes with creatively designed stickers and a special look for Pixel’s 10th anniversary.

Don’t be blue: Google is releasing an Isai blue edition of the Pixel 10A to celebrate the Android phone line’s 10th anniversary, setting it apart with its own sticker set, specialized wallpaper and custom icons. But it’ll only be available in Japan.

Announced Tuesday on the Google Japan blog, the Isai blue Pixel 10A has a dark blue look and includes bonus decorations designed in collaboration with Japan’s Heralbony art company. These include an exclusive bumper case and stickers for customization.

This edition of the Pixel 10A will arrive in Japan on May 20, following the April 14 release of the Pixel 10A in its original colors of lavender, berry, fog and obsidian. The Isai blue model costs 94,900 yen, which roughly translates to $595, and includes 256GB of storage.

This makes it slightly less expensive than the US model’s 256GB edition, but it comes with a number of fun extras at no additional cost.

Google’s creation of a country-specific model for Japan may also reflect strong sales in that market. In 2023, the IDC analytics firm (via 9to5Google) reported that the Pixel 7 series accounted for 10.7% of the country’s market share, a 527% increase from 2022.

Can’t Wait for New Emoji? Here’s How to Create Your Own on iPhone

Apple Intelligence-enabled iPhones can create custom emoji in a few easy steps.

Apple brought new emoji to all iPhones when the company released iOS 26.4 on March 24. The new emoji include «🫍» orca, «🫪» distorted face and «🫈» hairy creature — or as we might normally call it, Sasquatch. According to Emojipedia, there are 3,953 emoji with more on the way, including a pickle. But there’s no emoji for a dog wearing pajamas, a plate with burgers and fries and many other things. But if you have Genmoji on your iPhone you can create these emoji and many more.

Apple released iOS 18.2 in 2024 and the company introduced its own emoji generator, called Genmoji, to Apple Intelligence-capable iPhones at that time. The Unicode Standard, a universal character encoding standard, is responsible for creating new emoji, and approved emoji are added to all devices once a year. With Genmoji, you don’t have to wait for new emoji to appear on your iPhone each year. You can just create them as you need them.

Read on to learn how to use Genmoji on iPhone to create your own custom emoji. Just note that only iPhones with Apple Intelligence, like the iPhone 17 lineup, can use Genmoji at this time.

Note: The new emoji may not display correctly for Apple users whose devices aren’t on a 26.4 software version.

How to make custom emoji

1. Open Messages and go into a chat.
2. Tap the plus (+) button next to your text box.
3. Tap Genmoji.

You can then type a description of an emoji into the text box near the bottom of your screen and tap the check mark on your keyboard to enter that description into Genmoji. You can also tap different suggestions and themes that are right above the text box. And with iOS 26 or later, you can also combine and use emoji to create others rather than describing a new emoji or using suggestions.

Your iPhone will generate a series of new emoji for you to pick from according to your description, and you can swipe through these new emoji. When you find the one you want, tap Add in the top right corner of your screen and the new emoji will be available to use as an emoji, tapback or a sticker. Now you don’t have to wait for the Unicode Standard to propose, create and bring new emoji to devices.
