Spent a couple of early morning hours on Post Oak Creek this morning trying to beat the heat. We had a little rain the other night so I figured I would give it a shot. Someone posted a couple of weeks ago about snakes but I can tell you I saw less than usual, zero to be exact. The bigger issue is finding access. The usual spot was grown over and the only option was to go down on your rear which doesn't bother me much but once I slid down the challenge was to find a way up the slippery clay but that was something to worry about later. There was an abundance of teeth. There were tons of small foot prints that looked fresh so someone must have been out there yesterday after the Saturday night showers. They must have found the good ones but I did get a good haul of broken teeth with a couple of complete teeth for the display jars. Found a few bone fragments, a partial lobster, three gastropods and a nice bottle.

Have been in Europe the last two weeks and have been itching to get back out. I heard it has rained while I was gone and thought I would try my luck at Post Oak Creek. It was pretty dug up when I got there but some of my best finds are in others spill piles. Shark teeth were plentiful but quality was poor. Most were broken but I did manage to find a couple of complete Squalicorax. I only spent about three hours but found a few cool items besides the normal shark teeth. One appears to be possible coprolite and I found a nice piece of mosasaur bone as well as a horse tooth. I was also surprised to find the first Echinoid I have ever found at POC. When I picked it up, I was even more surprised to find out it was not just one but two Echinoids and a partial third together in matrix. Attached are some pictures of the day's load.

I made a trip to Post Oak Creek over the weekend and found 2 pieces sitting on the rock bank. They look like Mosasaur, but I am very new to identifying fossils. Any help with identification would be greatly appreciated. The ruler is in inches. On a side note, I also had a gar watching me the whole time I was there which was a first for me. I will post pictures of him in the Fossil Hunting Trips section.

I have been to Post Oak Creek a few times now and always had fun, but this trip was especially interesting. I was trying to make my way up creek via the shallow parts of the water. It was higher than I expected so I was trying to keep from getting stuck in the mud and going in waist deep water. I glanced over to the side of me and saw a gar about two feet away from where I was crossing. After a moment of shock I quickly got on the bank. I had no idea a gar would be hanging out right there. I was in that spot for about 4 hours and he just sat there with me the whole time. My goal was to head up creek some more, but the water was deeper and I was not going to take the chance of stepping on one his buddies. I had no intention of shaking hands with him (or fins for that matter). He finally swam up creek when I entered the water to go back to the bridge. He was about 3 feet long. Here are some teeth I found that day.

I brought home a bucket of gravel from Post oak creek in Sherman Tx. to sift through, and came across this beauty. The size is approx. 1.5 to 2 mm.

Hello all, I'm still a newbie to all this so I was hoping that some of you may know some different entry locations for Post Oak Creek in Sherman, Texas. I have entered at the Travis St Bridge and the Sherman Healthcare Center. The Healthcare Center was recommended by a local I ran into on my last trip. He said he has entered there regularly so I gave it a shot. There was a lot of glass and trash in that location so extra caution should be taken in that area. Can anybody recommend any other entry locations? Hiking is not huge concern I was just hoping for ideas. Has anyone ever parked at Binkley Park and searched Sand Creek? Is there anywhere around Post Oak that is unfriendly to hunters? I promise to leave some teeth for all the other hunters out there (but I would love to find my first arrowhead). Thanks in advance.

Hello all. My buddy and I went to the NSR and Post Oak Creek this weekend. I was hoping someone could help me identify a couple of finds. The first is one was found on the bed of the NSR. It appears to be bone, but it is very heavy (perhaps from soaking up all the grey clay since it was embedded in the bed). The second was found at Post Oak Creek and appears to be bone, kind of like a finger type bone (digit). We also found some nice teeth and nice baculite. This is my first post about my finds, so any help would be much appreciated. I was also wondering if anyone could provide some advice on where to look for fossils at the NSR. This was my second trip in a month (or ever for that matter) and I am having a really hard time finding anything. The baculite is about the most identifiable thing I have found. Should you look on the bed, the cliff side (it's all grey!), mouth of creeks, the creeks themselves...? Thanks in advance. Glad to be a member.

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!

Here are just a few of my finds over the last month in Sherman,Tx. My son and I have really enjoyed getting dirty. We have found tons but these are some of our best. Not bad for beginners?

Found these at Post Oak Creek but unsure of what kind of shark they are from. One I think isa small posterior makrel shark but Iwill leaveit to the experts. Thanks for any help.

found this bone in post oak creek in sherman a couple days ago ....any ideas what it might be?

Here is an unidentified partial turtle shell I found a few years ago at post oak creek. The area is upper cretaceous, eagle ford I believe. I believe that this is probably pleistocene though. It looks more modern to me. I performed a burn test on it and it is indeed mineralized(no penetration of a red hot needle or smell), I haven't had any luck on identifying it myself. 1 square=1"

I recently found what looks like a mammal molar while I was screening through some bulk sample material from Post Oak Creek in Sherman TX (Austin group). I usually just find marine teeth, verts, gastropods, brachiopods, etc.. But, then I found this little guy. The marks in the pictures are 1mm apart. Any ideas?

Since the weather was close to perfect here in N. TX today, I spent the early part of the morning lobbying my 8-yr old to make the 60 minute trip with me up to a favorite section of Post Oak Creek (Sherman, TX - Mesozoic, Upper Cretaceous) to spend the afternoon hunting for shark's teeth for a small jar we're trying to fill. We've made this trip 3 other times, so my hopes were high. Once he stepped out into the backyard and felt the combination of a warming sun tempered by a cooling wind, he was all systems go. Over the course of about 3 hours we found a bunch of broken sharks's teeth that were perfect for filling the jar, a few smaller really complete teeth, a possible shrimp or lobster carapace, a couple of super nice ptychodus teeth, a couple of bones/vertebrae (I'll post all this next), and one...really...large...tooth. At the end of the afternoon, on our way back to the car, we were eyeballing the driest route back across last "stream" area we had to cross, and my son said "Wait, Dad! I see a big tooth!". He ran around behind me and reached about a foot into the stream and pulled out something that looked all-too-disappointingly familiar: a big solid, rock-like object shaped in a vaguely and meanderingly conical toothlike manner. It was covered in moss, and I've had so few things of this shape actually turn out to be something organic that I almost dropped it back into the small stream whence it came. But, I had just exhorted him to put anything and everything he thinks might be fossiliforous into the bag because we could always clean it up and throw it out later if it was nothing. So, into the bag it went. Once we got it home, cleaned it up, let it dry and took a good look, there was no question it was a tooth. What a nice surprise! Just curious what the experts thought it might be (first thought was enchodus based on the shape, but it's completely round with no angular faces to it), and whether you can tell how big the actual animal might be that it came from based on the size of the tooth (right at 3")? Thanks in advance for any info you can pass along.
