Ihopeitsnotarock Posted May 5, 2023 Share Posted May 5, 2023 Found in south Wales on a mud flat at low tide. I’ve tried to clean as best I can. Any input would be amazing, please! I believe it to be an egg or 2 and a rib cage, or tubular crustacean formation, but I’m a total newbie, thanks!! Link to comment Share on other sites More sharing options...
Mahnmut Posted May 5, 2023 Share Posted May 5, 2023 Hello Ihopeitsnotarock and welcome to the forum! Ithinksitsdefinitelyarock, the question is, is it a rock containing fossils? If not a rock, worst case it could be concrete, hard to tell sometimes with weathered and overgrown pieces. The riblike structures do not look like ribs to me, to thick and close together, could even be one structure with a ribbed surface. Others more familiar with your region may know more.

Fossildude19 Posted May 5, 2023 Share Posted May 5, 2023 What is the size of this piece? @Tidgy's Dad 1 Tim - VETERAN SHALE SPLITTER VFOTM --- APRIL - 2015 IPFOTM -- MAY - 2024 _________________________________________________________________________________ "In every walk with nature one receives far more than he seeks."

Auspex Posted May 5, 2023 Share Posted May 5, 2023 The 'rib cage' bears a passing similarity to the sub-bark of the Devonian Sigillaria. I believe the 'egg-shaped' objects are siderite concretions, which are common in low-oxygen coal-swamp deposits.

Tidgy's Dad Posted May 10, 2023 Share Posted May 10, 2023 (edited) Looks like a chunk of badly weathered, crude, reinforced concrete to me. Edited May 10, 2023 by Tidgy's Dad 1 1 Life's Good! Tortoise Friend. Link to comment Share on other sites More sharing options...
Ludwigia Posted May 10, 2023 Share Posted May 10, 2023 Whatever it is, there are modern barnacles and bryozoa on it, so it's been lying in the water for quite some time. Greetings from the Lake of Constance. Roger http://www.steinkern.de/ Link to comment Share on other sites More sharing options...

Seems odd that a fossil would have turned up on a mud flat. Are there fossil deposits nearby ?? 1 MotM August 2023 - Eclectic Collector Link to comment Share on other sites More sharing options...
Advantage Posted May 10, 2023 Share Posted May 10, 2023 To my eye, this does look like concrete, I have seen plenty on the East coast where I live. And I have also seen plenty of barnacle encrusted concrete and old iron struts from the former pier we had encrusted with barnacles. So I`n going with a chunk of concrete.

Ihopeitsnotarock Posted May 10, 2023 Author Share Posted May 10, 2023 Hello everyone and thanks for all your inputs! I totally accept your beliefs that it is concrete, there are massive amounts of fossil deposits right next to where I found it including bones, vertebrae, teeth and the beach is famous for its marine fossil deposits. I will take more photos and post just to be sure as the surface of the supposed egg is cracked and fits the online descriptions I have read. Again-I will accept the identity to be concrete but i just want to be sure before I bin it, thanks again Link to comment Share on other sites More sharing options...
