    Fossil in matrix at online auction site

    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.
  2. 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
  3. 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.

    Unidentified Possibly Cochliodus

    From the album: Chondrichthyan Teeth From The Pennsylvanian Period

    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
  6. 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

    This one makes me go hmmmm....

    Found in NW Indiana. VERY heavy for it's size. It doesn't reflect well in this photo but the it is actually more greenish like a jade green. Fossilized organ? Endocast? Hmmmm.
  12. Hello all, Curious to see if you folks could assist me in the identification of this item. I came across this at an auction. Initially I thought it was a cast metal - non-ferrous (perhaps bronze) - depiction of a Peach, Lemon, etc., and was perhaps used as an altar fruit. But the material just does not quite fit the bill - unless the piece is made of quite ancient metal. Upon diving into research, I came across a "fossilized flint coconut" which had strong similarities, (however this piece has only one pore or 'eye') which then led me to learning about flint sponges, which also had strong similarities. Any thoughts or further resources would be greatly appreciated, Kindly, J

    Is this something?

    Hi, i found this around a lake in Germany, maybe it is nothing, I was just curious! It looks like a tadpole to me.
  14. I have no clue what this could be. Not a trilobite, not sure if it's a rugosan. Age: Late Eifelian Locality: Southern Belgium Width: 1,3 cm Length: 1,5 cm

    Eggs or Seeds

    Hi everybody first time here.I found a bag of polished stones none bigger than a quarter.I don't know where there from but I'm in Colorado so i take them home and put some of them under a microscope that connects to my computer and this is what i saw.The rocks themselves are dark red almost black in color about 1/2 inch long by 1/4 inch wide and corkscrew like shape.What are these how could these things get trapped inside the stone like this.if anybody has an idea of what these are let me know.thank's

    Unidentified dinosaur bone

    Can someone please help me identify what this may have come from? It was most likely found in South Dakota or Montana but I can’t be 100% sure. IMG_4025.mov
