Fossilised sea urchins, Echinoids.
These are old..... very very old.
Perhaps 65 million years, and maybe older 😲

In Surrey folklore, fossil sea urchins (Echinoids) are known as fairy loaves, shepherd's crowns, and thunderstones. They were thought to be enchanted, protecting the houses from lightning and bringing good luck to the home.

Day 9 of my mudlarking-themed Advent calendar featuring finds from the Thames Foreshore across many years 🎄
Fossils found by me at various locations on the river from east to west - echinoids including the heart-shaped Micraster, likely swept in via the Chilterns. Also Balanocidaris, not native 1/

U – Urchin
The colloquial name for echinoids is ‘sea urchin’, which comes from the old country name for hedgehog (urchin). They are quite common in the South of England and along the Thames foreshore, where I found these.

The term "cretaceous" is Latin for "chalk-like". The Period is named for the cliffs.
The unique geology preserved certain hard-bodied fossil impressions with fine minerals. Lots of echinoids, bivalves and sponges.
It's on my bucket list. Hopefully before it's underwater again.

#Paleoart from 2018 for #FossilFriday, a group of Mystriosuchus steinbergeri pursue fish around a Triassic lagoon. Phytosaurs like these are meant to be freshwater species, but M. steinbergeri didn't get the memo: aspects of their fossil preservation hint at marine habits. #sciart #fossil

Big #FossilFriday thanks to our curatorial colleagues @nhm-london.bsky.social who have been helping our project curate and register #chalk specimens! This week dealing with hundreds of cidaroid spines - these were originally attached to echinoids (sea urchins) which lived on the chalk seafloor.

I gave a paper years ago on 'odd' placements of echinoids on Roman sites which I'd completely forgotten about until I saw this post!

Fossil echinoids (prehistoric sea urchins) were known in parts of the UK as "Fairy Loaves," "Snake's Eggs," "Shepherd's Crown's" and, in keeping with this week's theme, "Thunderstones."
Their presence in the home was thought to protect the property from lightning strikes.

Always nice to spot one of these beauties on the foreshore. This is a small echinoid fossil, could be from the late Ordovician or Jurassic/Cretaceous periods. Some of the oldest echinoids are a mind-blowing 450 million years old. Likely this was washed into the Thames from the chalky Chilterns.
