howard Posted May 27, 2014 Share Posted May 27, 2014 I found this flint on the foreshore of the river Orwell in suffolk, it is about 4cm at it's widest & has what look to be small fossils looking out from it, any ideas what it may have once been ?

JohnJ Posted May 27, 2014 Share Posted May 27, 2014 Looks like the mold of a few echinoid test plates. Welcome to The Forum. The human mind has the ability to believe anything is true. - JJ Link to comment Share on other sites More sharing options...

Kosmoceras Posted May 27, 2014 Share Posted May 27, 2014 I agree, that's the negative impression from part of a Cidaroid type of sea urchin. Here's a link to a website that should help you find out more about it along with some photos of more complete examples: http://www.chalk.discoveringfossils.co.uk/ECHINOIDS.htm#Cidaroids I don't think your find can really be safely identified much beyond the family of Cidairdae, but keep a look out for more fossils in flint, echinoids are fairly common.

howard Posted May 28, 2014 Author Share Posted May 28, 2014 Thankyou for the link Kosmoceras, it has helped me name another fossil type i have, I notice the Bathysalenia granulosa, i think i may have found 2 of those on the orwell foreshore.

Howard, the photo in post #6 is not Bathysalenia granulosa; it is a partial irregular urchin of some kind - commonly referred to as "heart" urchins.
