Thames Adventurer Posted June 15, 2022 Share Posted June 15, 2022 Hi! I recently found these pieces of flint on the Thames foreshore (London) which look like they have seashells in them. The banded areas are raised/textured to the touch. Are these fossil seashells and if so, does anyone know what type they are or how old they might be? Thank you!

Lone Hunter Posted June 15, 2022 Share Posted June 15, 2022 I could be wrong but it looks like banded flint. Link to comment Share on other sites More sharing options...

I'm not sure about that as normally banded flint has different colours and isn't textured like these pieces are? But I appreciate all opinions on this matter.

Lone Hunter Posted June 15, 2022 Share Posted June 15, 2022 They would be impressions of shells if so and they look like inoceramus and scallop maybe. 1 Link to comment Share on other sites More sharing options...

TqB Posted June 15, 2022 Share Posted June 15, 2022 I agree the top one in the first photo is an inoceramid impression. The other is certainly a ribbed bivalve but hard to ID much further. Both in flint from the Upper Cretaceous Chalk, roughly 70-100my. 2 Tarquin Link to comment Share on other sites More sharing options...

When I googled Inoceramid,a lot of pictures of a giant shellfish came up. These flints are really small, so is mine a baby one or simply one belonging to that types broader genus/species?
