Richard T Posted October 22, 2020 Share Posted October 22, 2020 Hi, went fossil hunting with my family to Mappleton on Holderness coast last weekend and found this rock. Not sure what process formed it and whether it is a fossil or not, but it's got me really curious and I'd love to find out more if anyone knows. Has a kind of sticky out rim that goes around it. Thanks, Richard. Link to comment Share on other sites More sharing options...
Tidgy's Dad Posted October 22, 2020 Share Posted October 22, 2020 Looks like a concretion to me. https://en.wikipedia.org/wiki/Concretion 2 Life's Good! Tortoise Friend. Link to comment Share on other sites More sharing options...
dhiggi Posted October 22, 2020 Share Posted October 22, 2020 A lot of such concretions further up the coast in the Whitby area, sometimes contain fossils, sometimes fossils can be seen poking out. Very hard rock and a bugger to split or do much with though 2 Link to comment Share on other sites More sharing options...

Tidgy's Dad Posted October 22, 2020 Share Posted October 22, 2020 Sometimes, but I don't think so in this case. Whack it! 2 Life's Good! Tortoise Friend. Link to comment Share on other sites More sharing options...
Richard T Posted October 22, 2020 Author Share Posted October 22, 2020 Thanks all, did wonder about giving it a whack! Have recently bought a fossil hammer, as yet unused. Any tips for where to hit, how to hit? Should I try and chisel a little groove first or is it a case of just giving a whack and hoping for best?

Personally I’d go for a cold chisel and lump hammer on any obvious groove around the rim, but others may suggest a different approach. Make sure you wear eye protection and don’t whack it on the patio/driveway/front doorstep etc as you’ll probably break that before you make a mark on your find Link to comment Share on other sites More sharing options...

Notidanodon Posted October 23, 2020 Share Posted October 23, 2020 that looks like the kind of nodule that may contain some small eleganticeris ammonites in the middle, make sure to split it around the edge where it sticks out as if they are there they will be on that plane 3 Link to comment Share on other sites More sharing options...
LabRatKing Posted October 23, 2020 Share Posted October 23, 2020 Truth is this looks like a geologic to me, but with weathered concretions anything is possible. I have a limestone “cannonball” that I had on my desk for 20 years...and a custodian knocked onto the floor...it has a wonderful crab at the core! 1 Link to comment Share on other sites More sharing options...
Ludwigia Posted October 23, 2020 Share Posted October 23, 2020 Well this does come from a beach which does have concretions which could contain ammonites and other fossils, so I'd follow Will's advice if I were you. 1 Greetings from the Lake of Constance.

Top Trilo Posted November 4, 2020 Share Posted November 4, 2020 @Richard T Did you open it?
