I’m not an expert, but hoping to find one… This was found in a house clean out in North East Texas, stuffed in the back of a sewing desk drawer. I have no information on its history, seeing as the previous owner is now deceased. I’m looking for someone more educated than myself who can tell me some facts, or professional guesses. I would love to know what, when and where. Measurement: *Roughly* 4cm diameter, 2cm thick

Hello everyone, recently took a trip to mineral wells fossil park in mineral wells, Texas and as an amateur I was unable to identify a few peices. Maybe yall could help me out. not sure if these are fossils or not

I am unsure whether to post this in preparation or ID so I'm just going to post it here I recently found chunks of dirt in a creek bed near Lake Nagodoches, Texas, USA containing fossilized shell peices. while I was cleaning off the excess dirt, I came across these very brittle and strange looking "formations" (I'm not quite sure what to call them) on all of the chunks. Can anyone help me figure out if these are just excess stone or dirt or if its some kind of fossil. I attached some examples and a picture of the fossil as a whole. I'm a beginner to fossil preparation so excuse me if this is a dumb request

What are these five rocks, please? (Let's number them 1 - 5, from left to right.) They're from a geoscience professor's collection, and were given to me without ANY other information, so I can't provide any geographic or stratigraphic information whatsoever. Number 1 = basalt? Number 2 = agate? jadeite? something else? Number 3 = ? Number 4 is very smooth and milky-like. Mudstone of some sort? Number 5 = calcite? Thank you for any help!

This is a very unusual impression that has taken the shape of what looks to be a bi-pedal footprint. Obviously this flies in the face of known information about when bi-peds inhabited the area (mid-southern Vancouver Island), however its form, depth and measurements are almost perfect. Any ideas, info or opinions?

Okay so I found this specimen at the Taughannock Falls in Ithaca New York. I found it at the edge of the gorge which consists of shale, composed of slit and clay that fell onto lime mud and hardened into rock. I've done some research and it appears to be a Brittle star trace fossil formed by their arm grazing the sand floor. Although, these Brittle Star fish traces are known as "Pteridichnites biseriatus" and they have only been discovered so far in upper Devonian shales out in western and eastern Virginia. I'm not an expert but to my knowledge the Ithaca geological formation is Devonian and was slowly covered by sand. Is it possible that the Brittle Star fish once roamed in the ancient sea now known as "Taughannock falls" today? Because a research team is trying to find this specimen and they are wondering if anyone has discovered it. Edit: Im referring to the dotted trackway. check this link out for more information. http://www.wvgs.wvnet.edu/www/news/Pteridichnites.htm

Plant, Marine , or Burrow Fossil? Bishop's Cap, Organ Mountains, New Mexico
Jakk T posted a topic in Fossil ID
Please forgive my newbie ignorance. I just can't figure out what these are! Location: About 2/3 up Bishop's Cap at the south end of the Organ Mountains, New Mexico, April 2024. Research says it's probably from the Pennsylvanian era and in limestone. I suspect it's parts of a plant, although it could be a marine animal or burrow hole. Length and width 1 5/8 inches x 1/8 inches. Thanks!

I am not sure if this forum is still active, but will give it a try. I found this fossil on the north shore of Nova Scotia. I have come across many tree fossils in the past, but I am not sure about this one. At first glance I thought fossilized corn? My next guess was possible seed cone from conifer tree? I have never seen any fossils like this before and was hoping someone could help solve this mystery. Note, on many of the lumps there is a tiny dark ring. I tried to get the best pictures I could on my old camera. I also added a picture of the reverse side, which also has some odd shapes in this very fine sediment rock.

From the album: Chondrichthyan Teeth From The Pennsylvanian Period (Missouri)
One of my teeth that I really want to identify. It was mentioned it could be a broken or partial Petalodont crown minus the root. 13cm in size -
Unidentified (reptilian?) bones from Mühlheim Quarry (Solnhofen), Germany
DrGrant posted a topic in Fossil ID
Dear members of the fossil forum I am contacting you because I need help in identifying an interesting specimen that I am currently preparing. The find is larger than I initially expected and seems to extend over the entire slab. Originally I thought it was the humerus of a pterosaur (Rhamphorhynchus sp.), but on closer examination under a stereomicroscope I noticed strange "nodules" on the surface of the bone. As far as I know, these are atypical for pterosaurs. The further I dissected, the stranger and more confusing the specimen became. I would never have expected to come across the parallel pieces, some of which lie under the bone and have a T-shaped cross-section. It comes from a limestone quarry in Mühlheim and I have been given permission by the owner to take it home for further examination and preparation. However, even he is at a loss as to what this "structure" is. Based on the colouring in the transverse fracture, he suspects that it could be a reptile rather than a fish. After extensive internet research, I have ruled out the possibility that it is a plant, an arthropod or an echinoderm, but I am happy to be corrected. Thank you in advance for your help and I look forward to your comments. Kind regards DrGrant

Hi. Would anyone be able to confirm what this tooth is? And who would carve it out to use as a decorative personal item? Thank you so very much.

Hi! Once again, I’ve been looking on online auction site and came across these fossils in a matrix. I only have pocket money to use on it. It is cheap, but I wished to know whether it worth the money. There are more images I can upload.

Help Identify this "frog" Rock? Fossil? Coprolite? Coral? Magical carving?
Rufus posted a topic in Fossil ID
Hello and thank you for looking. I found this rock in a dry river bed in Nayarit state, Mexico, near an ancient petroglyph site next to the river. I always thought it looked like a little frog, but have not been able to figure out what it might be. I really appreciate your help. It's heavier than the common volcanic lava rock from the area.

L.S., Some TFF members may recall that I've posted about this specimen back in 2018 (this post, to be exact). This weekend, I'm going through drawers with fossils to try to identify some old finds. After looking at this particular specimen again, I think the tentative ID "cf. Zoophycos (?)" from six years ago is probably not correct. Therefore, I'd like to resubmit this one for evaluation by the esteemed TFF membership once more. The overview photo below (please click to enlarge) shows three spiral structures on the right hand side and a larger "C-shaped structure" more to the centre of the image. Combined, the three spirals are 16 mm long (distance measured as seen vertically on the overview photo). The second photo shows a microscope image that I made today. At least the lowermost spiral seems to be surrounded by a "hairy" rachis-like structure, with narrower hairy stems going in between the segmented structures of the spiral (possible pinnules?). Back in 2018, I did not have microscope images to share on TFF and the suggested ID as "cf. Zoophycos (?)" made sense to me (at least the specimen ended up like that in my current database). But looking at the fossil again, I think this really is something vegetative. Fossil fiddleheads (Spiropteris sp.) are well-known from the Carboniferous, but these would be the smallest ones I've seen. The nature of the C-shaped structure wasn't really resolved back in 2018, but could this be related to the supposed fiddleheads somehow? Could the C-shaped structure represent remnants of a seed for example? The area "connecting" the C-shaped structure and spirals shows a lot of interesting texture with additional/overlapping, even smaller spirals (?) but is rather rough and difficult to photograph (see third photo though). The "innards" of the C-shape are relatively flat, but this may caused by the straplike leaves/stems that seem to be preserved in a plane just above the other structures. You can see this layer-on-top quite clearly on the third photo, at the end of the rachis of the leftmost spiral and directly to its right. Yet I do not dare try remove this layer and risk damage to the fossil... Given the really tiny size of the spiralled leaflets, I was wondering if someone here knows of any literature on "seedlings" of Carboniferous plants? What would that very early ontogenetic stage look like? Some examples for comparison would be great! Thanks for your interest, Tim
