  1. rapp creek hunting

    My hip is bothering me, but we've had beautiful weather the last few days so I had to get out. Ended up being a short trip. Most of what I found was broken and small and about half as many teeth as usual, but I tried. Tape is in cm. A three inch ecphora, but missing a tail. Two or three skate stinger pieces. A nice but hard to scan cowshark upper, and pieces, some fin tilly bones, a few angel shark and drum. Lots of animal tracks along the creek but no frogs, crawfish or salamanders, just scud shrimp.
  2. Mysterious sea tooth

    I have found this thing in a campanian marine phosphate deposit. It came along with fish and shark teeth. It looks like some kind of tooth, but I have no idea. The brown area is translucent and looks like enamel. Although the grey is thicker and sharp. Any experts on cretaceous fish would be welcome Ps. This is definately not just a rock, I am fairly familiar with this deposit and can judge a rock from a fossil. Could anybody I'd this please?
  3. Rapp beach trip

    Went out after the snow here, not expecting much. Found a dozen or so small teeth (one small mako?), a flat (porpoise?) partially hollow tooth, some coral on a scallop, skate teeth and a nice piece of stinger, and-- finally-- a bunch of shrimp coprolite burrows (had not seen any in a longtime, but the storm deposited several; posted photo on that thread). Bunch of "whale' bone" chunks. A fun day.
  4. I found this tooth (Rajiformes?)

    I fount it in marine sandstone, but I don´t know what it's. Age: Probably Maastrichtian.
  5. Stingray Barbs

    Do you ever look at your fossils and say, ok that's enough, I have plenty? haha.... I have many more stingray barbs...... I think I've reached my capacity of them.....
  6. Hello! I found this chunk of something in Frankstown, MS while looking for shark teeth. There is so much petrified driftwood there and many pieces look similar to this. I picked this out at first thinking it was wood.. but I didn't see the little bumps along one side (I'm being very generic because I don't want to call it something it isn't and I'm not sure yet what it is ) until I got home. I also noticed when I got home that it is hollow and looks a bit like bone. After seeing this, I thought it was probably a fin spine or a ray barb. Others say it is a barb, but if it is, I'd love to know more. I would think it would have denticles along both sides, but the other side is rounded. Rays found at this location are Brachyrhizodus wichitaensis and Brachyrhizodus mcnultii. Specimen is 2" long
