Sea urchin like? In natural flint matrix

[JorisVV]

I found this thing as a 10 year old in France. It is definitely one of my better findings on the flint coast there. I think it's an urchin but I don't have much knowledge about urchin and like fossils. Could anyone help me specifically what it is?

Beautiful find!! Definitely an echinoid - notice the 5 radial symmetry. I am sure someone on here will be more knowledgeable about specific genus.

...possibly a Conulus sp.

Nice find.

Size? Provenance more precise than France ? Normandie ?

I think it’s an Echinocorys.

Normandie and around 9 cm

Does there appear to be an opening in the top?  It's hard to tell from the flash on the image.

I agree with Echinocorys
