I have had this rock for a number of years and have often wondered whether it was an just oddly shaped or a fossil, if anyone would be able to help it would be very appreciated :) thank you

Im no expert by any means but I was thinking of a bivalve mollusk or some kind of gastropod.

The rock is flint. This was formed during the Cretaceous era in a chalk sea. Flint only formed in the upper chalk so I am confident to give it an age from 70 - 90 million years old. I am pretty sure you have a cross-section through an echinoid (sea urchin) called Echinocorys scutata. Could you send some more photos of a side-on view of the specimen to look out for confirmation (or exclusion) details?

Many thanks,

Thomas

I think Thomas has it.

Is this quite a common fossil? I found it somewhere in England not sure exactly where though

Urchins are fairly common along the South coast, in flint is rarer than in chalk, but not all that rare.

Echinocorys is a very common (and important) echinoid found throughout the White Chalk above the Terebratulina lata zone. Here is one of my specimens preserved in flint which is worn but shows the plates well.
