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?

Millions of years ago during the Silurian period, the Sahara Desert was a shallow sea full of aquatic animals like crinoids. Don’t be fooled! Crinoids are commonly called "sea lilies" but they aren't plants! They are echinoderms, like starfish and sea urchins, and many species are still alive today!
