hndmarshall Posted October 17, 2018 Share Posted October 17, 2018 ok not quite sure what these are find one every now and then...they have an odd coating dropped a couple in the acid bath for a few minutes and looked at them through a microscopic camera and found all sorts of little goodies... so wondering could these be some type of poo??.....fossilized feces. Coprolites...??. ..fish? turtle? lizard?...?? Link to comment Share on other sites More sharing options...
Rockwood Posted October 17, 2018 Share Posted October 17, 2018 I think you have exposed fossils, of what I do not know, by maceration of chunks of limestone. I think coprolites are usually phosphate based. Link to comment Share on other sites More sharing options...
Asteroceras Posted October 17, 2018 Share Posted October 17, 2018 Look like chunks of flint stone to me, in our area you can get echinoderms and very rarely crustaceans in flint Progress of my fossil cleaning can be found on my Instagram feed http://instagram.com/gbfossils YouTube for fossil collecting and prep videos https://www.youtube.com/user/GBFossils Link to comment Share on other sites More sharing options...
hndmarshall Posted October 17, 2018 Author Share Posted October 17, 2018 not sure ...the outer coating feels kinda silky but harder than it feels... takes a bit longer to dissolve if it even does once dipped and wet the color darkens considerably ....the one I cut open above was red and black inside finding all sorts of things on them after soaked and still wet....why I thought they may be coprolites. dont think they are flint plenty of that in the gravel piles and does limestone come in reddish and a dark grey? tried the sticky test yes sticky but as to how sticky they are supposed to be i dont know dont have any real coprolite to compare to.

The little goodies weren't there before or you didn't look for them before ? 1 Link to comment Share on other sites More sharing options...

Sounds like the acid may have only washed away a weathered layer, instead of dissolving carbonate matrix as I thought. Link to comment Share on other sites More sharing options...
Carl Posted October 18, 2018 Share Posted October 18, 2018 I don't see coprolites there. I agree that they look more like chunks of limestone. Link to comment Share on other sites More sharing options...

The coating being like clay matted on as the carbonate dissolved. 1 Link to comment Share on other sites More sharing options...
