NEED HELP!!! Is This Just an Iron Concretion or A Preserved Fossil?
Kurufossils posted a topic in Fossil ID
Hello 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.- 19 replies

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? (the pics are just snipets of general info that I came across online)

Need help identifying a group of spherical fossils | Solved : Iron Concretion
Alexander D.G posted a topic in Fossil ID
I found this one at the Jurassic Coast along side some other fossils. The fossil is about 2.5 cm wide and is heavier than it looks (tried a magnet but it had no effect on it). The second picture is a close up of a crack at the side (top right on the first picture), from what i could make out it looked like pyrite which is most likely becuase i also found a pyritised ammonite on the same beach. Any help would be greatly appreciated!
