A lot going on here. Found an oddity yesterday trying to figure out if petrified wood or bone. The outside of it shows evidence it rolled in sand a while. Plus confusion is outside layer looks like an old bone look. My past petrified wood finds in comparison. Next my petrified wood is being studied to figure out tree and timeline. It's very rare even though up to 26 pieces found in one location. Next a paleontologist did confirm the one find was a tooth. Less than a mile from petrified wood location. Im making big discoveries but learning even more. A geoscientist is talking to me on almost a daily basis. He is a Dr at a university. I am very grateful with his help and patience. If anyone can figure out if petrified wood or bone thanks.

Hello, I am looking for some info on these three crusher shark teeth that I have. They were unidentified and without provenance when I acquired them, but based on the other material in the collection they were from they might be from the Pennsylvanian of Texas. There are 3 specimens and they range from 4.5 cm to 7.5 cm long in size. This is #1 and the largest: This is #2: And #3 the smallest: I had actually asked about these last year in this post, where @connorp suggested they might be from a genus called Fadenia. I wanted to get some targeted identification on them if possible, or perhaps get into contact with a paleontologist that could give a professional opinion. Thanks.

Hello, I have two slabs that I would like ID help with, one is a hash plate with trilobite cephalons and pygidiums, the other has a crinoid calyx/crown. I'm told they were collected in Reynolds County of Illinois, USA. I did some googling and I don't think there is a Reynolds county in Illinois, but there is a Reynolds village in Rock Island/Mercer County Illinois which is what I'm guessing the seller meant. Anyways, assuming this info, the geological map of Illinois suggests that this locality consists of the Tradewater Formation which is Pennsylvanian in age: https://isgs.illinois.edu/content/bedrock-geology-map-illinois The crinoid calyx is small at just 1 cm across not including the very long primaxil spines. From what I've seen, primaxils produced as spines is a feature that seems uncommon in most geological periods but commonly seen in many Pennsylvanian crinoids. So I'm more convinced that the crinoid is Pennsylvanian. On the other hand, the trilobite cephalons (also measuring about 1 cm) look very much like calymene/flexicalymene which are Silurian/Ordovician genera, so I'm a little more doubtful here. Anyways, here are photos. First the crinoid plate: And the trilobite hash: Thank you.

Hi guys! I have a few fossils found recently that are not identified yet. The first is thick and looks like half of a round object. I found it near Payson AZ. The second wasn't too far from the first. It may be coral from what I can tell. The third is from a place called the Paleo dig site 13 miles from Payson. It's a conglomerate of many different sea mollusks I think? There are at least 4 different looking shells I found all around the site that seem to be agatized. Any help id and for the conglomerate of shells, how do I safely remove the mudstone or limestone to expose the shells more? So far I've used a soft toothbrush to brush away the junk. I've included 3 angles front and back. The last conglomerate has fossils on both sides. Side #2 looks like sea daisy's maybe?

This specimen was discovered by my grandfather over 30 years ago in the coal mines of north-western Alabama. This area sits on the black warrior sedimentary deposit and is well known as a hot spot for Pennsylvanian age plant fossils. ~18 inches in length .

Picked this up by the Poteau River near Wister Ok. I’m pretty sure it is geological but the taper and twist are throwing me off. It is 9.5” tall.

Found in Greenwood county Kansas area, not sure if bone fragment or part of jaw fragment, found in area where previously found Shark teeth. Any ideas from the group what this fragment is?
