Ryann10006 posted a topic in Fossil IDHello everyone, I am in desperate need of help with a huge debate I have been having with a friend over fossils preserved in ironstone concretions. From some of what I had read to some advice from other members I it possible to find vertebrate bone among shells and other mollusks preserved in an ironstone concretion. Whether it leaves a trace of the organism, morphs the organic material into the structure of the iron concretion through the decomposition with preserving, or whatever else it may be it seems to be possible. So recently I have hunted a place known to have recorded marine cretaceous shell and other mollusk found in ironstone concretion as well as cretaceous plants in shale, it seems like not to vast of enough study has been done there only from what I know, but since no vertebrate material had yet been discovered there though there can maybe be the possibility. I found these two particularly distinct pieces in iron concretions that exactly mimic the scute structure of soft shell turtle and croc in my opinion, I know how iron concretions are famous for leaving psuedofossils and such but these two pieces look way to exact and since its possible for shells and mollusks to preserve why not scutes? So I am here looking to end this debate, I'm looking for your opinion, can these be labeled as fossils, traces, etc? Or are these among some of the world's best iron concretions and nothing more. Your input especially if you are very experience in this subject would be tremendously appreciated.
I dont know if this is the appropriate place to ask but I thought I would go to the source to ask. Looking for people that have some crab from NZ that they wouldn't mind working a deal. trade or sell. PM me if you or someone you know can help. It's one of the fossils I'm looking to add to the collection and since I love to prep it should be a win win.
Hello I present an interesting question that I'm not to confident to answer myself and am seeking help from the more knowledgeable. Since it seems like (from what I had seen) iron concretions can at rare times preserve certain fossils or traces in one way or another such as molluscs, brachopods, and such. Due to this would it be possible for material such as turtle shell scutes or maybe even croc scutes to turn up in such concretions in one way or another?
