PerthBloke556 Posted August 7, 2022 Share Posted August 7, 2022 Hi all, hoping someone can tell me what these bits might be. The kids found them digging around/in a Cretaceous limestone chalk and greensand. Took them out there for a fun day, no idea what we were going to look for or where. Hoping someone can identify any of it. Thanks in advance Link to comment Share on other sites More sharing options...

The flat round pieces, real confused what they might be. Just rocks but nature doesn't build them flat or straight... Link to comment Share on other sites More sharing options...

They are super flat and looked out of place in the chalk and sand. The next ones the big round one that looks like a ball joint. Might have to crack it open and see what's inside... or cut it in half. Going to have to invest in a small wet table saw. 1 Link to comment Share on other sites More sharing options...
rocket Posted August 9, 2022 Share Posted August 9, 2022 (edited) cool, Inoceramus could reach up to 1 meter and perhaps more and the shell reached a thickness of more than 5 cm in some parts... go to dig a complete one , should be big I am a bit unsure with this one: could you post a pic from the other side? thanks Edited August 9, 2022 by rocket Link to comment Share on other sites More sharing options...
debivort Posted August 9, 2022 Share Posted August 9, 2022 Are we sure the flat fibrous pieces are fossils and not a seam filled with a fibrous mineral like gypsum? Link to comment Share on other sites More sharing options...

PerthBloke556 Posted August 9, 2022 Author Share Posted August 9, 2022 Took a few better photos of a find. Thoughts? Found in gin gin chalk Thoughts on removing the matrix without damaging the fossil? Chemical? Mechanical? Link to comment Share on other sites More sharing options...

Not easy, but I would try a combination of small chisel (do you have air pen?) and KOH, sometimes a hard brush (try if it is not too hard for the shell...) helps for the first cleaning Link to comment Share on other sites More sharing options...
