D.R. Johnson Posted September 19, 2018 Share Posted September 19, 2018 Hi. I was given this fossil today and I was wondering if anyone could tell me what it is? The guy who gave it to me said he found it at the side of a dam somewhere in England but he had the feeling that the rock used there had been imported from elsewhere. There is a white crystal at one end of the stone (possibly quartz?) and I believe that the fossil is preserved in the same crystal. Not really sure if it is a fossil of a crystal formation in the rock? I can supply more images if needed. Link to comment Share on other sites More sharing options...
Tidgy's Dad Posted September 19, 2018 Share Posted September 19, 2018 Would have a stab at (Devonian?) rugose 'horn' corals, myself. Very nice. 3 Life's Good! Tortoise Friend. Link to comment Share on other sites More sharing options...

D.R. Johnson Posted September 19, 2018 Author Share Posted September 19, 2018 Thank you both. So where in the world are these corals found? Here is another picture of the specimen. Link to comment Share on other sites More sharing options...
TqB Posted September 19, 2018 Share Posted September 19, 2018 They are rugose corals, lower/middle Carboniferous rather than Devonian. It looks very much like Great Limestone from County Durham (not actually a marble but a limestone) - the corals look like Dibunophyllum and Koninckophyllum but I'm not sure of the scale there. There's a famous ornamental layer in the limestone called Frosterley Marble and that could be a bit of it - it's widely used as a hardcore rubble in the area. (There are similar limestones elsewhere but it's fairly distinctive.) Much of the Pennines is made of Carboniferous limestone and corals like that (and other fossils) are frequently abundant. 3 Tarquin Link to comment Share on other sites More sharing options...
