Got a family day out to coast, Speeton and Reighton. My Son had a good sift through the stones at the base of the clay cliffs and made some finds. He was absolutely over the moon with his haul, I wanted to share. Devils Toenails, an Ammonite, a small bivalve and a few things of interest that we have yet to ID.  Click image for larger version - Name: 20200718_152302.jpg, Views: 48, Size: 188.27 KB Click image for larger version - Name: 20200718_152309.jpg, Views: 49, Size: 215.11 KB Click image for larger version - Name: Screenshot_20200718-101517_Gallery.jpg, Views: 51, Size: 78.55 KB Click image for larger version - Name: 20200718_152344.jpg, Views: 48, Size: 206.57 KB

What a wonderful haul.


The Belemnite is probably local to the Speeton Clay- there are alternating layers of Speeton Clay with big, bullet-shaped ones and slender ones that taper at either end.  They reflect populations of Early Cretaceous squid that invaded from the north and from the south respectively, in successive waves.
Your ammonite in a nodule is probably Dactylioceras, from the upper part of the Lower Jurassic (from further up the coast)
The Gryphaea  and the single bivalve (which looks from this angle like Cardinia) are also from further up the coast, derived from the Lower Jurassic, 190 -200 million years old. The Jurassic fossils will have been transported to Reighton with the Ice Age glaciers which dumped the thick layer of dull pebbly clay unevenly over the Speeton Clay.  Almost all the beach pebbles here originate from this material.

The glassey pointy rock on picture 1 (counting 7 across from the left) is a piece of Flint. The left rock in picture 4 is either an Iron or oxidised Pyrite nodule and the middle rock on picture 4 is (possibly) Jet, although its shape is unusual making it difficult to tell.
