Hi all I found these two fossils in Post Oak Creek (Sherman, TX) today and would appreciate any input as to what they are. My guess on the first one is that it is part of a turtle shell, and the second one is part of a crustacean. Thanks!

So I was searching through the remaining material I had from a trip to POC. I’ve had this material for a few weeks and I randomly go back look through it trying to find more micro teeth. When looking today I found two items that were a bit different than the other items I found. Anyone that can help me identify what species the small tooth is would be great. Not saying it’s rare but it just looked different than the probably 50 I found. Also the other chunk looks to be a piece of jaw with two small teeth connected. At first glance I thought it was a broken piece of tooth it the more I looked, it looks like one of the teeth is whole and not fractured or cracked. Any opinions would be great!

Found these little fragments when looking around in Post Oak Creek near Sherman, Texas. To me they resemble rodent teeth, and I've certainly found non-fossilized ones out there, but these are definitely fossilized. Any idea what they could be? Largest fragment is 16mm long and 4mm wide. Close up shot is the wider end of the fragment, which shows a really cool cross section of the piece.

So my 8 year old son and I did our first ever trip to go find fossils. Attached is what we found in our very untrained 2 hour trip! Haha I literally have no experience outside of reading on this forum from time to time. We may have just picked up some rocks but they looked like fossils to us. I know most most of the teeth are probably goblin and I believe we found 2 Ptychodus. The main things I’m wondering about are the long piece slim piece next to the Ptychodus (possible whale tooth?), two vertebrae looking pieces, the egg shaped piece, and the white pieces. Not sure if they are bones of if they are just random trash we picked up thinking they were treasures. Haha All our tooth fragments Item on right? Egg shaped item Vertebrae? Vertebrae? Cant tell if this tooth is broken or just worn Cool little shell in a rock formation No clue? Looks like bones in rock but could be just river muck This looks like a little flipper but not sure

Here's a couple of quick hunts I forgot to post from the last two weeks. Post Oak Creek and North Sulphur River Texas. I really like the ammonites.

Hey guys and gals. My hubby and me have been tromping around in Post Oak Creek (Sherman, Grayson Co. Tx.) and he came upon this tooth... I for the life of me can't figure this one out. Is it just part of a shark tooth?

I have found a few of these over the years and just found two more. I have no idea what they are but they are all identicle and roughly the same size about a half inch or so. I found them at Post Oak Creek in Sherman TX. I have found arrowheads here as well which makes me wonder if they could Be man made. As always I appreciate any feedback.

Scale in photo is in mm. I'm thinking this may be a Ptychotrygon triangularis tooth. MIGHT be Ptychotrygon hooveri, but it looks to me to be a closer match to the triangularis. One of my latest finds while sifting through my load of gravel from Post Oak Creek.

Found this odd claw-like bit today while sorting through gravel from Post Oak Creek. Any ideas as to what this might be? Scale is in mm. Dark photo just to show scale. Both sides of the object. The best shot I could get of the "proximal" end of the thing.

Just starting to sort through all of the fine gravel from Post Oak Creek that I collected on July 11, and I've found these so far. Scale on lower right is in mm.

Not a massively productive hunt. Coupled with SOMETHING under the bridge smelling like Every Dead Thing In The Universe, plus nearly getting my car trapped by loose gravel. Anyway, on to the shark tooth pics. Scale is in cm. First, the broken teeth. Then THIS little guy! Don't ask me how I managed to screen-sift a small tooth with its root still in matrix out of a gravel bed! I would have thought that tumbling down those gravel beds would have broken it right off! As it is, I'm gonna have to glue it eventually. It's got a crack in the root that you can see in 1 pic, and the rest of the tooth is REALLY loose in the rock.

Found these in the Post Oak Creek in Sherman, TX. Eagle Ford and Austin Chaulk contact. Need help with ID ing these items. Thanks in advance for your help.

I discovered the fossil forum in January of this year, and once my boys and I got the bug, I started using the forum for the usual information that newbies need. Where to go. How to search. What is this thing. Where can I find. You know . . . all the usual stuff. One of the places here in Texas that I found on the forum caught my eye, and I tucked it away in the back of my mind. It was a report of finding shark teeth in the Post Oak Creek in Sherman, TX, which is a good 3 1/2 hour drive for me. So, obviously, I didn't just hop in the ole truck and drive north. But I did have the opportunity to pick where I wanted to spend the night last night on my way home from a trip to Missouri. How about that! Sherman, TX! As luck would have it, the hotel I used was less than a mile from the Taylor Street bridge, the place most folks had said was the place to begin the journey. And it just so happened that I had a pair of waders in the truck, which aren't necessarily needed, but were a convenience to have while moving from gravel bar to gravel bar. But let me not get too far ahead of myself, for I think there are some lessons to be gleaned for newbies like me on the forum. I read everything I could on the Post Oak Creek and finding shark teeth in Sherman, TX. Tons of advice. And I assumed I understood what it all meant. But I didn't. Before I reached my hotel, I went to the store and bought a 5 gallon bucket, a gardening shovel, and a cheap cake pan. I found a nail and punched some holes in the cake pan so that water would be able to drain through. Now the bucket part was explicitly laid out in one poster's instructions and, I did follow his advice on taking some gravel home to search through -- the boys found 35 teeth in a quarter-filled bucket! Now back to the error of my ways. I had read something about sifting through the gravel, which is why I guess I started in like I was panning for gold. I found nothing by doing this. I even cut my pinky finger on my home-made pan. Here's lesson one: Don't make up a method when you don't have to! After 45 minutes of nothing and figuring I was doing something wrong, I remembered the many posts that said "look in the gravel bars." So I went to the one nearest me at that point, and bam! found my first one. I ditched the panning business and set to work, and the previous posters are all correct. Just look in the gravel bars (above the water, not in it) and those little beauties are there to be found. Once I knew what I was looking for and where and how to look, my search was more productive. Lesson 2: Follow the advice of forum posters. Lesson 3, that I quickly learned is to focus on the color of the teeth. There are plenty of pics on the forum to study and remember that they are shiny compared to the other rocks they are lying next to. My 4th piece of advice would be to stoop low to the gravel, it narrows your focus, and remember, some of these teeth can be quite small. So, as you can see in the picture, I did end up getting a taste of beginner's luck, and my boys were jealous that I went without them. But we did spend an hour sifting through the gravel I brought back and that excited them quite a bit as they found so many small teeth in there. Oh and here's my summary for finding teeth in Post Oak Creek: - Waders are handy, but not necessary. Especially in summer. Just wear swim gear if you plan to go up and down the creek. - Study so that you know what you are looking for. - begin your search by looking at the top of the gravel, no need to dig, as you will find them lying there. - get closer to the ground - No need to pan for them. - Take some gravel to sift through on a cold winter night when you wish you could be out fossil hunting!
