Symphyseal teeth are found in the midline of the shark's jaw. They are usually small and squashed-looking. Since only a few rows produce these teeth, they are much rarer than other positions.-

The fossils in the creek can have varying levels of preservation: from the pristine glassy enamel seen at the top, to more river-worn seen below.-

This last weekend produced probably the best results I've ever experienced while fossil hunting - these last two days will be hard to beat. Before I get to that though, I do want to include a find from the weekend before (since this is the topic of rarity). It was a local find and a first for the species for me. Not only that, but my first real "heartbreaker". It was bound to happen at some point! Sticking halfway out of the gravel, I instantly recognized a large Ptychodus tooth, of either P. marginalis or P. polygyrus - I couldn't remember at the time which of the two was the younger, but regardless both are rare and would be a first for me. (spoiler - it's P. polygyrus)(EDIT: I forgot you don't find polygyrus in Texas - this is probably a P. martini then (also rare, woohoo!). With great anticipation I pulled it out - only to realize that it wasn't half buried - just broken in half! Despite the realization, I was still ecstatic, heightened by the fact that this was on a scout to a new spot as well. But, that't not what y'all are here for, so without further adieu, let's fast forward to my time last weekend. I at first met up with Kris ( @Ptychodus04 ) up in north texas to take a look at a woodbine site where he discovered the holotype of Flexomornis. That's right, our own forum member discovered north america's oldest definitive bird! It was an estuary-esque deposit, and I was curious about what potential the site had for dinosaur fauna ( a newly inspired interest ever since my time romping around in the hell creek formation). We found some powdery bits and pieces of chunkasaur, as well as some tiny amounts of croc, fish, and bird materiel, so the excursion was quite informative for me. Kris brought his old friend and hunting partner Joe, and the three of us were chatting it up the whole time - it was a morning well spent. Before the day became too hot, we turned back and Kris offered to take me to a cenomanian Eagle Ford site in the area. I have a very hard time running into the lower Eagle Ford, so I was happy to accept, and we hit the creek with the sun high above. Now, you won't catch him tooting his own horn, so I'll do it for him - Kris is an insanely skilled collector. He and Joe have made some bonkers discoveries that I had no clue about - new things, completely articulated things... his 40 years of collecting experience has a track record that shines. In our first ten minutes into the creek, something coming out of the weathered bank caught my eye: 10 minutes prior, as we were walking in, I joked to Kris about finding a fully articulated Coniasaurus here. Coniasaurs have been bouncing in my head for a couple months now, ever since having an energizing discussion about them with Mike at SMU (the first time I found out they even exist). They and Pseudomegachasma were why I was so bent on finding cenomanian Eagle Ford, and this being my first time In cenomanian eagle ford strata, I had my fingers crossed.... and it seemed to work! I didn't want to be the boy who cried coniasaur... but I was fairly positive that that's what I was seeing. Kris was right behind me and seemed to agree - so, I drove a pick in below the vert to pry it out... and out came another vert locked into attachment with it, freshly broken in half. Silence. I looked at Kris, Kris looked at the vert, and we both went "oh!" From this alone, I was starting to get very excited, though I had to remind my self that odds were low that it would be all I was imagining. Kris (thank god he was there and could take over the digging, literally the best person for the job) began exploring deeper, and the vertebrae continued. Joe continued a little further up as we dug. Soon, we had a line of them exposed. Keep in mind, this is without 1.5 verts that broke off with the initial discovery: If you look to the left of the closest to the screen vert, you can see a tiny rib piece (which I originally assumed to be a process) The verts continued still, and then my phone overheated, so the pictures had to stop. Here's one that Joe nabbed of the scene: Paraloid was slapped on and Kris removed the first major block. A spot of bone on the other end looked to be on the side, so we moved in further and revealed another block where the bone seemed to finally stop. Covered in sweat we then continued our hunt. While looking at a pyrite inclusion, I practically stepped on a Xiphactinus tooth. Kris spotted it as I walked away, I was shocked I missed it! This sort of find is almost casual for these two (yeah, they're good), so he offered I keep it. I was happy to accept - it's the best Xiphactinus tooth I've personally seen. Our walk was mostly uneventful from there, right until we got to our turn around point. Kris and I realized at some point that we left Joe where we had turned around, and I went back to check on him. He was under a large overhang, where he had pulled out few plates of shale containing bone. Since both of them have found many large fish on this creek, they didn't bat an eye, but I was amazed! It seemed there were some skull elements of a large fish on them. "Are there more? " I asked "a little", said Joe, and he showed me where he spotted them. After a few seconds of moving materiel, we revealed another large piece of bone, and I about died. However, not too keen to excavate, considering it's fairly insignificant materiel for them (and the heat was oppressive at this point), we left for Kris's place. I told them I planned to get right back as soon as I got in my car, and they wished me luck and told me to send updates. Back at the site, I revealed the bone quickly, and in doing so, more bone that was previously buried revealed itself 10 inches to the left. I began on that, and soon realized I was working on a HUGE vert. "Xiphactinus it is then", I said, as nothing else from this portion of the cenomanian (except perhaps plesiosaurs) could produce something this big. As I continued work though, I started losing faith in my ID. The bone itself was nothing like fish. The day was drawing to a close, and I drove back home with a renewed interest in the mystery vert. I arrived home late. Then, early the next morning, I woke to do it all again, but first on the list was to drop off the coniasaur at SMU. I mentally prepared myself to spend another $90 on gas and then set out loaded with energy. I stayed at SMU for several hours - it's always a pleasure to spend time there so I didn't mind getting out to the dig site later than expected. It didn't take long for me to finally remove the vert... and revealed behind it was another...yes!! Happy to finally be out from under that overhang, I looked hard at what was in my hands. Both sides were revealed now, and I caught my breath. This was certainly reptile. I showed some photos to Mike at SMU, wondering about Plesiosaur, and he decided that while it would need some prep first, he doesn't think so. This leaves Archosaur origin, if I dare suggest. Some more field photos are below: (During the dig) Once removed: Unbelievable two days, to say the least. I'll have to return this weekend, and I'll update this thread as necessary. The site though is in the worst possible place it could be - at the back of an overhang held together by only the roots of a cedar, whose exposed roots hang like a curtain behind you as you work. It's going to take some work to make that safe, and more work to dive in from there, but I'm rearing to go. What a weekend - if I wasn't typing this at midnight I'd probably write much more, but that's the jist of it for now. Stay tuned!

I stopped by a housing development that cut into Kamp Ranch Limestone and found a few teeth. Most of the teeth were in a chunk of sandy matrix I broke up at home.

I made a drive down to a creek in Grayson County yesterday morning. Grayson County has had several inches of rain in the last couple of weeks, and I wanted to see what that might have uncovered in one of my favorite spots. After my misadventure with sticker vines on my last visit to a creek in this area, I was armed with leg and arm chaps, but I didn't think I would need them for this spot, and sure enough, even though it's also more grown up than the last time I visited, the chaps stayed in my backpack. There was a lot more water in the creek than the last time I was here. The water covered part of the gravel bars still, and the parts of the gravel bars nearest the water were still wet, so very dark and harder to spot fossils on, but I still found plenty. I do love this spot. Here are some in situ photos.
