Living sharks have innumerable tiny scales, but their earliest relatives somehow grew larger bony plates. In our new Biology Letters @royalsocietypublishing.org, we work try and out how, arguing they grew by fusing and remodelling spines and scales.

Just woke up from a social media pause and the first thing I see is an incredible footage of a sperm whale casually cruising with a giant squid in its mouth ??

New paper is officially out!
Ratfish have a second jaw on their foreheads - CT + histology show they’re real teeth, built from the same tissues and signals as oral teeth.

www.washington.edu/news/2025/09...

This common fish has an uncommon feature: forehead teeth, used for mating

New findings call into question one of the core assumptions about teeth. Adult male spotted ratfish, a shark-like species native to the eastern Pacific Ocean, have rows of teeth on top of their heads,...

Did you know we are one of two journals produced by the Natural History Museum London. We champion the importance of collections-based systematics and our papers cover fossil species from across the tree of life, substantially contributing to the systematics of extinct taxa. So, why publish with us?

For #fossilfriday the toothplates of the LARGE Cretaceous elephant shark Edaphodon (L), from @sedgwickmuseum.bsky.social. Living elephant sharks (R) can get a little over a metre long, but Edaphodon's toothplates suggest it was elephantine in scale as well as trunkage, growing to over 3 metres! 🐘🦈

Beetles are the most speciose animal order: 25% of described animal species are beetles. Everything has to start somewhere, though, and for #FossilFriday, here is the earliest known 'beetle' - the 297 million year old Coleopsis, found in Freisen (Saarland, Germany).

A photograph of a fossil insect in a rock. The rock is beige fossil black, and kinda patchy in colour. It has a head towaerds the top, and the majority of the fossil is two easy to spot wing cases, which is how we know this little dude(tte) is a beetle.
