Is This the Footprint of One of the Last Neandertals?
The fossilized print, found in Gibraltar, is said to date to 28,000 years ago, which might mean it belonged to a Neandertal. But not everyone agrees with that interpretation

Bringing a Fossil to Life: Reverse Engineering Locomotion
How an animal moves can tell scientists a lot about how it lives. That is how researchers hope to learn more about an ancient crocodilelike creature called Orobates pabsti. Using scans of an Orobates fossil, fossilized footprints, and data from lizards and salamanders, researchers created a dynamic simulation of how Orobates moved, which they brought to life using a robot. To start your own investigation into Orobates’s movement, explore the free online tool here. This video was reproduced with permission and was first published on January 16, 2019. It is a Nature Video production.
