    Identification help

    I found this on the banks of the Trinity River in the DFW area of Texas. I spoke with an archaeologist online who guessed it to be bison or bovine of some kind. He guessed that it was considerably old because he could see mineralization in the photo I showed him. All I can tell is that it is a thoracic vertebra, approximately 3 1/2 in by 4 in in size. I cannot tell if it is fossilized or just a bone nor can I tell if the color is due to age or sediment discoloration. Would love to know what anyone thinks and if they could point me in the direction websites that might have answers. Thanks!
  2. Someone on a facebook thread brought up something I'm not familiar with. Yeah...add it to the list. LOL If I understood it right they said some Cretaceous Period bone and wood has been found that has not undergone any physical change. The material was on the North Slope in Alaska so I wondered if it had anything to do with deposition in permafrost. They said it is not that uncommon but I don't recall coming across this in any textbooks or descriptions of preservation methods. Does anyone know of any other places where this has occurred or how it would be possible for anything organic to l
  3. This post is about a well preserved Gravicalymene celebra molt I recently found in the Laurel member of the Salamonie formation of Southeastern Indiana. It is quite a peculiar specimen since it appears to have two very distinct mineral compositions. Most of the trilobite is composed of dolomite as is typical for fossils found in the Laurel. However, I initially noticed what appeared to be white calcitic pieces of the cephalon partially exposed at the anterior end of the specimen. The matrix surrounding these pieces was very easy to remove, having a fine sand like consistency. After some prep w

    Chew on this... please.

    I thought these were horse teeth, but after some poking around I'm thinking they're bison teeth. Please, help with identification and geological era. I'm starting with photos of the two that look like bone, in what stage I don't know, but do have three more (one large and two small) that I believe to be completely fossilized teeth from the same animal. All were found in Bucks County, Carversville exactly, in or near a creek bed at the bottom of a ridge of cliffs, which, we've been told, is a very special geological location where finds are not typical of the surrounding area. Because I c

    Devonian oddity

    Just got back and am beat from a day at Arkona. This one is a bit strange. Just when I think I've seen every odd pattern, ichnofossil, mineralization, and concretion type in the Widder shale, I get a curveball. Or should I say a snowflake?. specs: Mid Devonian (Widder Fm). Arkona, Ontario. About an inch. I can't seem to find it, so this pic was taken in the field. I might have lost it.
  6. Hello everyone, this is my first time posting, I absolutely love this forum. I've decided to register and dive head first. I've recently moved back to Southern Arizona from Florida and I have rekindled my love with rocks, and now fossils, since it would seem I've been finding many of them from all of the ages. Please help me identify this find, it looks carnivorous of some sort, it would be cliche to say it looks like a raptor, but indeed it does. It would be hard for me to believe that this is a fake, since there is also tons of evidence that would point to this being real. (If it is, I'll po
  7. On February 2nd, the Finger Lakes Mineral Club will be having an open house event at the Museum of the Earth in Ithaca, NY. We're in the planning stages now, and I'm working on assembling the displays I want to bring. One of those will be about different mineralizations that fossils show. At present, I have a number of limestone, shale, and sandstone fossils to choose from, including a few brachiopods that appear to have the original material preserved, plus a few examples of types that are less common and possibly unknown to the general public: -- Opalized shells from Australia -- Petrifie
