New Members vik1984 Posted Wednesday at 09:28 AM New Members Share Posted Wednesday at 09:28 AM I found these rocks / fossils on charmouth beach, Devon uk. Someone said in passing they were Coral. I was given the dark one and told it was coprolite. I’d love any help with ID. They were just on the beach mixed in with everything else. The dark one is heavy for its size. thank you Link to comment Share on other sites More sharing options...
Rockwood Posted Wednesday at 10:34 AM Share Posted Wednesday at 10:34 AM Sorry. This isn't coral. It looks like chert to me. The darker one isn't a coprolite either I'm afraid. Concretion seem more likely there. 2 Link to comment Share on other sites More sharing options...
Fossildude19 Posted Wednesday at 10:59 AM Share Posted Wednesday at 10:59 AM Chert nodules, possibly showing imprinting from sponges. @TqB 1 Tim - VETERAN SHALE SPLITTER VFOTM --- APRIL - 2015 IPFOTM -- MAY - 2024 _________________________________________________________________________________ "In every walk with nature one receives far more than he seeks."

val horn Posted Wednesday at 11:36 AM Share Posted Wednesday at 11:36 AM The dark circles are over pyritized amonites i believe. 3 Link to comment Share on other sites More sharing options...
TqB Posted Wednesday at 11:36 AM Share Posted Wednesday at 11:36 AM They're Upper Cretaceous flint nodules and do indeed show sponge impressions. (In the UK, "flint" invariably refers to the Cretaceous stuff from the Chalk which is a variety of chert.) The dark one is pyrite, quite likely grown around an ammonite but definitely not a coprolite. 4 Tarquin Link to comment Share on other sites More sharing options...
New Members vik1984 Posted Wednesday at 12:16 PM Author New Members Share Posted Wednesday at 12:16 PM Thank you everyone, I find them beautiful so it’s nice to know what they are. I think I should go on a fossil walk with an expert and learn what to look for. Thanks for taking the time to help 1 1 Link to comment Share on other sites More sharing options...

There's something to be said for the type of learning that you already seem to have a knack for. Link to comment Share on other sites More sharing options...
val horn Posted Wednesday at 07:28 PM Share Posted Wednesday at 07:28 PM Been there did that and found it very helpful to take the museum tour. It was inexpensive and a great learning experience and the museum has remarkable fossils. Link to comment Share on other sites More sharing options...
