Hey Gang, Looking for some help on what these guys are. Family and/or Genus would be great. Probably Tampa member of the Arcadia formation? Hillsborough county, Florida. Miocene? Here's unfortunately a real lousy comparative photo of the other specimen, but with a much better view of the shape of the aperature. Any help is appreciated. Thanks! Regards, Chris
Hey Gang, Ran across some matrix recently that had some very small teeth in it and I'm wondering if there is enough there to get an ID on any of them--two of them appear to have cusplets. They are very small 3-7mm and just trying to position them and turn them over to photograph without having them pop up and fly onto the floor was interesting for these fumble fingers. Here are some group photos-- if individual clearer photos are needed let me know. Thinking these are probably Miocene from the Tampa member of the Arcadia Formation here in Hillsborough County Florida--best guess based on our county geologic map but I'm still working on narrowing down some invert iDs found from the same matrix. A couple more view of specimens 3 & 4. If they are too beat up and non descript I understand..Suppose clearer photos might help as well...ugh! Thanks. Regards, Chris
I found these bivalves in Panther Creek in Frisco, Texas. They were found in a cemented sandy layer in the upper part of the Cretaceous Arcadia Park Formation (Turonian) which is part of the Eagle Ford Group. Could this be a Plicatula Sp.? One shell is 26mm x 26mm; the other is 19mm x 19mm.
DinoMike posted a topic in Fossil Hunting TripsApril 9 was my birthday, and what a coincidence... it also happened to be a day when Dallas Paleo Society had a field trip scheduled into the Martin Marietta quarry down in Midlothian, TX... and I got on the list. The first "find" of the day was when Polly, our trip leader, presented me with a birthday cupcake. After signing our release forms, the DPS crew was led into the quarry. We were taken to an area where they had just dug up some fresh rock. Everyone scattered about the area, and soon the "clink.. clink..." of rock hammers on shale was heard everywhere. (Just for the record, the site is in the basal Atco formation of the Austin Chalk.) I wasn't doing so well. Nothing seemed to be turning up in the older section that I had decided to check out, so I wandered back over into the new area with everyone else. Nothing much happened in the first few minutes of surface collecting, then I saw THIS... My first ever fossil fish tail! Probably no chance of ever getting a genus or species ID on this. Still, it's Cretaceous Fish, and that's good enough for me. I was lucky that the slab had split right there, so both the tail & counterslab were right next to each other. I sat down and started going through the other rock in that area, and found this, too: Might be part of the same fish, but I think I'll have to do a bit of prep work on it to be able to tell if it's head, body chunk, or what. I have the fish material stored in a temporary jacket til I get time to lay some Butvar-76 on it. (Continued... )
