Found in a creek in Floyd County Kentucky. Area is Pennsylvanian (according to the university of Kentucky website the area may also have a very small mix of Cretaceous, Tertiary and Quaternary). I'm wondering if this is a fossil, like an impression of a seed or something, or if this is just a weird rock. Thanks in advance.

Hey y'all I'm sorta kinda Curious what this maybe .. help this mama out please. My husband recently brought this very unique find in to me. Its from one of his many East Tenn creekin' adventures . We both have never seen a formation, limestone rock, or a fossil quiet like this: it's way heavier than drift wood or most carcass bone.. What makes it different than most rocks I've got is the difference skaly ridges which reminds me of a curled up lizard tail on one end...I have attached a couple of pics may have to zoom in the following pics. Thanks in advance for any ideas or possible ID.

i found this is se ohio in a creek and i think it is petrified wood but i am not sure

I was creek walking today and found this 15 lb piece of petrified wood. I looked up similar sized pieces but I feel like this may be "extra cool"? I don't know much about fossils but I have a passion for wood formations and this seems to be a knot from the tree with the burl or tumor in tact on the back side. My question is if it were to be sliced would it be more valuable because of the natural swirling of the burl? Or is this even a cool find at all? I'm new here guys haha! Thanks in advance for any input or comments!

Hello all, I am new here and this is my first post. I recently found this tooth while fossil hunting on a creek in summer county Tennessee. I was mostly finding crinoids, coral and a few other unidentified relics when this caught my eye. At first glance I thought it was a horn coral as I’ve found a few of those on this creek, but it quickly became apparent that it was actually a tooth that I initially thought was from a large cat or bear. But after a little research I don’t think it’s from either. I can’t seem to positively ID it, although it sorta looks like a croc tooth or maybe a whale tooth. It’s really worn down by time and the elements but I think there’s still enough there to be recognizable. The enamel seems to have a grain to it. And the rest of it is completely mineralized. I was hoping someone here may recognize exactly what it’s from. I found it pretty much on the surface in a small rocky creek that is loaded with crinoid stems of all colors shapes and sizes. I’ve found coral there and some clam type fossils also, along with some other types of unidentified fossils and peculiar looking rocks. I’ll probably make another thread for some of the other interesting pieces I have, but this tooth is by far the most intriguing thing I’ve found as of yet. I used Ordovician as a tag but I’m really not positive that’s accurate for this tooth. It seems that Tennessee has fossils from several different periods. So if there’s any questions I may be able to answer that could help pin point a time or whatever feel free to ask. But for some reason I have a feeling someone will probably know what it’s from by sight alone. I’ve always been interested in rocks and fossils but I’m a complete newb when it comes to actually ID’ing most of them. I’m originally from Louisiana and fossils aren’t near as plentiful there. I think it’s already developed into an addiction...
