I found this at Charmouth Beach but not sure what this might be. It's hollow and the inside has the light brown bumpy impressions running all the way through. The surrounding rock looks to be flint. Any suggestions on its ID are very appreciated! Ã°Å¸ËœÂ

Hi Rebecka
Could be a sponge, they do occur preserved in flint

That would make sense, I have never found a hollow sponge impression like this before, thank you for the help! ðŸ˜ƒ

Hello Rebecka and welcome to the forum. Yes, this is a flint with the impression of a sponge within it. The flint looks have to settled on a burrow in the seabed whick contained a sponge (washed in)? The actual sponge has then been eroded away. This will have eroded out of the late chalk formed 70 - 85 million years ago.
