Are you right- or left-handed? You may have something in common with this 550-million-year-old animal! 🤯 👉 Meet Spriggina—the world’s first “right-handed” animal! Long before dinosaurs, this little organism crawled along a slime-covered seafloor and preferred bending to the right.

Scientists have discovered a 518-million-year-old fossil that has the earliest known evidence of spiders’ fangs! 🕷️ Using X-ray analysis, researchers found two pincer-like limbs emerging just behind the animals’ eyes, which are thought to be precursors of the fangs used by modern spiders.

The pangolins’ iconic pinecone-shaped scales have made them targets of wildlife trafficking. New DNA analysis has revealed that populations of Chinese pangolins living in the Himalayan foothills are actually a separate species. This distinction could be vital in helping to stop illegal poaching!

Had a wonderful time presenting the Natural History Museum’s livestream last night, giving a first look at the fantastic new exhibition, Jurassic Oceans! 🐟 The exhibition looks amazing, and it was great to speak with some of the scientists who brought it all to life. 👏

This is really cool! 😮 DNA analysis has revealed what may be the oldest genetic evidence of domestic dogs. Several fossils found across Europe and Türkiye indicate that dogs may have been widespread by at least 14,000 years ago. Check it out 👇 www.nhm.ac.uk/discover/new...
