Ryann10006 posted a topic in Fossil IDHello everyone, had a super quick trip to the cretaceous creeks of new jersey and found this particularly interesting large bone fragment, likely it is a chunk of miscellaneous bone material but it reminds me alot of a scute like ankylosaurus or some sort of other bone scute especially the edge, or from maybe something like a large turtle but I am entirely not sure if it's dinosaur, marine reptile, etc or if there is anyway to tell, looks super suspicious to me anyways so if anyone has any ideas I'd definitely love to hear them. (If more pictures are needed I will definitely be able to get some more angles if necessary)
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.
