Hi guys my fiancé and I have gone for a holiday out near Porthmadog in Wales, we went for a walk along the beach yesterday and found what I think might be a starfish fossil but it’s not on a rock I’m not sure what it’s on or if in fact is a starfish fossil, sorry we don’t have a ruler and can’t wait a week to find out what it is lol, any help will be much appreciated Click image for larger version - Name: 93501BAB-DE72-448B-AD5F-CDAF3364891E.jpeg, Views: 30, Size: 2.78 MB Click image for larger version - Name: BC475F60-DFFC-46C1-A985-6A8E1ECDE596.jpeg, Views: 27, Size: 4.10 MB Click image for larger version - Name: 97A7D0BC-9D70-4D37-9A27-AEFCCFBC1B7B.jpeg, Views: 23, Size: 2.70 MB

Hello Craig and welcome to the forum.
Not quite a 'starfish' but it has the same symetry and so it is an Echinoderm (sea urchin group) and a very nice one as well. I think it might have been transported there by a glacier, but to give you more information I really need a profile photo and it's dimensions. Also, can you tell if it has been in / is made of flint?

Hi prep01 thanks for the quick reply, I don’t think it’s on flint it’s really light and hollow, we are still away so we don’t have a ruler but to have a guess it’s around 5cm wide by 5cm tall and about 3.5cm thick I’ll attach some more pictures of it, just stumped on what it’s on if it’s some sort of bone?

Hi

Really nice echinoid, looks twice as wide as the 20p in the photo, ruler is best, as Colin says need to know how tall it is.

Is it really a fossil? It's an exceptionally well-preserved one if it is, but it almost looks like a "real", i.e. modern, one to me ...

It's a modern echinoid, Echinocardium cordatum, aka "sea potato". They get washed up from time to time, sometimes in large numbers after a storm.

MFM and Craig I had my suspicions but didn't think there were modern heart urchins, so I've just Googled it and bingo! It's a modern 'sea potato'!!!!!
