BionicNeko Posted March 6, 2023 Share Posted March 6, 2023 (edited) I am back with another one I cant quite work out! Being quite amateur I am still learning, so apologies if I'm mistaken on rock type etc. This was found on the jurassic coast of the UK, on the beach near Charmouth and is in shale/mudstone so already trying to break apart as you can see. I've been wondering if it's a sponge or root of some kind, or just mineral like pyrite as it has a goldy metallic sheen in some light, although it seems too brittle for that and has got what looks like more calci(?) layers when I look at the ends. Any help from all of you lovely lot would be greatly appreciated! Side note: if it is a fossil is there a good way to preserve these delicate shale ones to avoid the crumbling? I've been looking at the guides but there is so much information I might be tying myself in knots a little Edited March 6, 2023 by BionicNeko Preservation Link to comment Share on other sites More sharing options...
Ludwigia Posted March 6, 2023 Share Posted March 6, 2023 There's a lot of marcasite/pyrite to be found in these layers along the coast and this is what it is. 1 1 2 Greetings from the Lake of Constance. Roger http://www.steinkern.de/ Link to comment Share on other sites More sharing options...

Thanks so much! I suspected as much but started second guessing myself (wishful thinking!) 1 Link to comment Share on other sites More sharing options...
TqB Posted March 6, 2023 Share Posted March 6, 2023 I agree with Roger. It may well have formed along a burrow - organic matter decay often initiates pyrite formation. 1 1 2 Tarquin Link to comment Share on other sites More sharing options...
Rockwood Posted March 6, 2023 Share Posted March 6, 2023 It looks a bit latrine like. Maybe an especially organic burrow ? 1 3 Link to comment Share on other sites More sharing options...
