  3. Florida Miocene Inverts

    Here are a couple of inverts that I found at a dry land site last year, put them in a cigar box and then forgot about them. I ran across them again while digging through my boxes. I managed to ID a couple of them (not shown), but a few eluded my ID attempts - I am not very good with inverts (many are similar). Does anyone know what these are? Any help would be greatly appreciated. The big one is 5 inches across and appears to be a cast. Another is some kind of scallop (I think) and the last photo is barnacles of some kind. These were all found in a spot that was rich in Miocene inverts.

  7. Moroccan Mystery - Coral or Brach?

    Hi all, I just got back from Arizona where I spent a couple of days at the Tucson Gem Show. On my quest for coprolite treasure at the Moroccan village, I came across this little mystery piece. I'm assuming it is some type of coral or brachiopod. The dealer only had a handful of these and this one had the least damage. Can anyone identify it? Any guesses on the age? When I first saw it, it reminded me of the septarians in this thread. Obviously, they are not the same.

  18. Post Oak Creek - Oyster with Anomoly

    So I went to north Texas a few weeks back. Stopped by NSR and Post Oak Creek in Sherman. Both were pretty flooded still, which hampered my efforts. Had a very meagre haul, which was disappointing. Back in Houston, about a week later, I was going over my disappointing finds, after a good washing. That's when I noticed an oyster I picked up in Sherman had a rather unusual anomaly. It was odd that I even picked it up - I already have several nice oysters of this variety from the same location. I try not to take home too many duplicates, usually leave them for the next guy. Well, this was a surprise. And I would say made the whole trip worth it. Oyster and Sherman experts, tell me your thoughts. The anomaly appears spherical in shape, entirely back material, high gloss. I do not want to prep the object or to try to remove, as I feel it adds incredible charm to a rather ordinary fossil. Sherman, Texas. Eagle Ford Formation, Cretaceous.
  19. Fossil sites around CT

    Hi everyone, I am new to this form and would like to know if there are any fossil sites in the general area around Connecticut. I myself live around Danbury CT and am not sure what places I could visit that are at most 4 hours of driving away from here. I have read about sites in PA like St.Clair and Carbondale but I believe both are closed now. Red Hill is also around that area but I don't know how I would get permission to go there. Also I don't really have a preference on type of fossil plants, fish, invertebrates, everything is welcome. Thank you

  22. Ordovician: Echinoderm scale?

    Finally, I have a fossil with some geological information associated. This piece is from the lower Ordovician Wah Wah Formation, specifically Section J in the Confusion Mountains in western Utah. I believe it might be an echinoderm scale. I would be thrilled if anyone could verify that and/or add any additional taxonomic information for me. Thank you so very much for your thoughts, and please let me know if you need additional photographs and I will do my best!
  23. This is a piece that I picked up on a geology field trip years ago in eastern New Mexico. I apologize that I have unfortunately lost the field notebook that contains more specific location information, but I am hoping to get in contact with the teacher that took us there for other reasons and might be able to provide additional information if I can ask him. The section was Cambrian to Ordovician in age: it started with abundant stromatolites, then progressed into thrombolites and finally siliciclastics disappeared during the Ordovician sea level high-stand. If my memory serves, I believe these were found from relatively low in the section and so should be Cambrian, but it has been long enough (about 12 years) that I would not stake my life on that. Since it may be hard to tell from the photos, these are essentially organic material on the surface of the rock with no visible depth at all. I am honestly a little stumped on this ID and, without the field notebook, I simply can't remember what my professor said about them; I remember that I did not know the word he used at the time, but I was new enough to invertebrates that that could mean almost anything. My best guess is that they are gorgonians, but I am probably several phyla removed from the right ID. I am happy to take any additional photos if they will help. Thank you for your thoughts!
