Hi

I found this fossil whilst I was digging to create a garden pond at around 3ft deep. It appears to be an Octopus tentacle or a sea urchin, could someone possibly identify this as well as an idea in regards to the age? 

Thanks

Hi Mjones, Nice imprint of Cidarid sea urchin in flint. Haven't access to many books at moment but could be something like Hemicidaris intermedia.

Nice, it looks to be in a flint pebble which would make it's age late cretaceous (approx. 70-80 MYA). H.intermedia is apparently a Jurassic species so probably not that (if it is flint). But certainly a Cidarid type sea urchin.

Yes I know H.intermedia is Jurassic - just giving an example. Try http://www.chalk.discoveringfossils.co.uk for Cretaceous Cidarids
