  2. Nothing too exciting, typical trip, highlight the perfect mako. No cow shark teeth last two trips. A lot more activity in "my" spots. Overdue to find something really nice!
  3. I was very fortunate to obtain some loose matrix and chunks of matrix that I need to break down. I really have only been working on the loose matrix so far. It has not m.uch but has been extremely productive with amazing teeth. This is the first time I have gone through matrix from this area and the colors are amazing. The matrix is absolutely loaded with so much great stuff. Most of the items I have found so far are firsts for me. Enjoy the pics! @JBMugu I have barely scratched the survive with the big chucks of matrix but these two verts came out of it. They cleaned up nice!

    Squatina sp.

    From the album: Cenomanian Shark Teeth and other Marine Fauna, Ryazan Oblast, Russia

    Squatina sp. (Dumeril 1806). You typically find more Cretorectolobus at the quarry instead of Squatina.

    rapp creek hunting

    Went out and played in the mud while still relatively warm. Quiet, not much wildlife activity. Lots of broken stuff. Hit an old spot, hoping for cowshark teeth, but didn't find any. Did get two angel shark teeth and a bunch of drum teeth. Several vertebrae, mostly broken. Found another skate stinger piece. Less sand tiger spikes than usual. One of the triangular teeth (sort of in-between a spike and a triangle, the pale one just above the stinger was unusual in that it was three times as thick and heavy as similar sized gray shark teeth blades, possibly thicker than the biggest triangular tooth. Fine serrated edge, don't know if a different species or just a weird tooth? @cck Any ideas?

    Rapp creek hunting

    Made two trips to the creek while worrying about Dorian; one trip to the beach, but not much there (picked clean by Labor Day visitors? Only one olive shell and a few bleached, worn small teeth.) I pooled the stuff collected in trips from the same general area in the creek. One of the trips I used a slightly coarser screen, followed by a window screen in response to @MarcoSr excellent recent post "What are you missing????". Since my teeth are micro-sized to begin with, I was sure that there would be lots of new stuff to sort through. Unfortunately, I was disappointed in my initial characterization of the "fines". I cannot see well looking about in the creek, but am very near-sighted and think I can see most of what is there at home (but will retry with a different substrate spot; the spot I was digging was fine gravel and shell bits). I do see more smaller drum teeth. Some bone bits and a few angel shark teeth (may have damaged the roots on them as well with the double screening, always wondered if screening was why my cowshark teeth were often rootless?) No nurse shark or cookie-cutter shark teeth yet, but still intrigued. The two trips were mostly sand tiger teeth, mostly rootless or small root spikes. Some were glossy and nice but I'm guessing the gravel takes its toll. A couple of verts, a small piece of a bonito nose(?), a bunch of angel shark teeth (a few with broken triangular bases; I stood them up for the scan). A bunch of drum teeth (and small round rocks, not shown). One ugly worn cowshark tooth. One for sure small mako, and a few that I cannot see any serrations on (micro mako teeth?) More serrated triangular teeth than usual for me, mostly gray sharks, but one worn-on-the-tip hemipristis. Two tooth pieces, one relatively flat with what looks like hemi-serated edge of enamel, and one heavier, triangular edge with finer serrations that I think, hopefully, is a smallish megalodon. If so, this is the first meg that I have seen from the creek since a kid found a big one thirty years ago there (teeth were much more plentiful, but meg teeth were always rare there).

    rapp creek hunting

    Went out to my usual creek which had dried up. Too difficult to strain out the sand, mud, black leaves, and muggy and buggy. Decided to try a deeper creek, and while not as promising, it was pleasant standing in running water watching frogs, salamanders, tiny shrimp and crayfish in my strainer. Not much, one small mako/ great white. It was nice to find an angel shark tooth, which I had missed recently. Used to be the second most common behind sand tiger shark teeth.

    rapp creek hunting

    Headed back to the creek; local kids have been busy, a lot of energy into digging, and changing channels in the creek bed. At one spot I saw something barely protruding above the sand, looked to be a huge mako! BUT, it was just a sliver; i had the tip and probably most of the 2" blade edge (no serrations), and no root. The story of my life! Looked hard for more, but nothing. Found three angel shark teeth, one with an unusually big base, a bunch of mostly broken drum teeth. Found the usual sand tiger sharks, a couple of heavy based tiger shark teeth (rare in the creek), skate teeth pieces and one partial stinger, two fin Tilly bones, a broken bonito nose, some elongated "teeth" (at least one had enamel on the tip end), two vertebrae and two vert pieces, and assorted gray shark and requiem shark teeth. Some stuff is small fossil, but no idea what it is. Found one heavy 8" bone, guessing cow. Great to be out, saw birds eggs in a nest, lots of frogs and a few salamanders, crayfish and lots of scuds/freshwater shrimp..

    Rapp Creek hunting

    Spent extra time looking for a spot, wandered the creek trying holes (not so deep). A few spots that looked spectacular and virtually a wall of shells yielded nothing. Most spots where there were loose shells in the creek also had small teeth (mostly broken sand tiger, nothing spectacular or big). Overall lots of teeth, but quality was not great. My "best" spots required a lot of digging. But the weather was nice, Spring-like and it was a pleasant hunt. Found ten or so drum teeth, three ecphora (one small one is complete), four angel shark teeth, a tooth in matrix (I don't see many of those, fine serrations), badly broken cowshark, four vertebra-- all different. Most of the triangular bull shark/ dusky/ gray shark teeth I find have fine serrations, two today had pronounced (including the biggest tooth), but not as striking as the usual hemipristis(?). Found a tiger shark tooth, much more common on the beaches. So still looking for a good spot, lot of digging ahead, but a good problem to have.

    Angel Shark

    A very nice example of a Lee Creek Squatina. An uncommon tooth.
