I obtained some matrix from the Aguja formation, which is late Cretaceous, from Brewster, County, Texas. I have been finding all kinds of good stuff, but will start with the following. The first two pics are from what I believe to be a therapod - maybe Tyranasaurid? There are approx. 5 serrations per mm. The next two are of an unidentified tooth. The last is a group photo of what may be Champsosaurus teeth? The hash marks are 1mm. Any ideas?

I spent less than an hour because it was to hot but I found the pice of vaculite and a small piece of bone.

Thoughts on this Tyrannosaur tooth for sale from the Aguja Formation of Texas. 2" Seller indicates some resto has been done to the tip to make it complete.

What is the consensus on the name of the formation exposed at Mineral Wells Fossil Park? I've seen both Keechi Creek Shale of the Mineral Wells Formation, Strawn Group, Missouri Series (Pennsylvanian Period) and I've seen Salesville Shale, Desmoinesian. Does anyone have a citation for a peer-reviewed paper that provides empirical data supporting the formation name given and correlating it with other exposures?

These tiny fossils all have a groove along the long axis. The surface is textured, but not reminiscent of bryozoan zooecia. Are these perhaps crinoid pinnules? Mineral Wells fossil Park, Keechi Creek Shale, Mineral Wells Fm., Late Pennsylvanian (Missourian). Scale in mm.

Any ideas what I have here?

Last time in Ladonia Fossil Park.

I saw the first opportunity to get back to the North Sulphur River yesterday when the temps were going to be below normal for a change. There was a really nice breeze blowing down the river. Went to a spot on the river that I have only been to once before and access is pretty poor. Thanks to whomever added the rope, it helped, especially getting out! Quantity of the finds were low but the quality of what I found was great. Found the largest Tylosaurus tooth I have ever found with a diameter just under an inch. Also a shark tooth and one nice mosasaur vertebrae. I always enjoy the chance to find an artifact, ever though they are rare, or at least for me they are? I liked the way that JarrodB displayed his artifact recently, so I photographed this one the same and it turned out pretty good. Not sure the type, could be a Marshall, usually I find Gary's, so this was a nice departure. I will be watching for another cooler than normal Texas summer day to get back to this spot.

Fun morning hunt at NSR. Pretty good sized shark tooth for NSR.

I only had a couple of hours so I stayed right below the creek bridge. I had a couple of cool finds.

I'm new to the site and have several interesting finds that are needing some identification! Me and my 8 and 9 year old boys have been digging away and are all very interested in knowing what we have. Google just isn't doing it lol! Any help would be greatly appreciated!

Okay guys! I've been talking my little boys fossil hunting at Post Oak Creek in Sherman since they let out of school for summer. Trying to get them interested in it and FINALLY!!! My 8 year old(least interested) found this. Please tell me this is a t-Rex tooth!! We are all pretty stoked regardless but would love some insight. Thanks!

Found on the Brazos River in Texas in Pleistocene gravels. Any thoughts?

I know very little on Pleistocene fossils but I always thought the horses that roamed during the Ice Age were much smaller than the modern ones. I found this large solid rock horse cannon bone fossil at the North Sulphur River Texas which is comparable in size to the modern day ones I find. I'm 100 % sure it's a fossil. Sorry I can't take measurements but I'm offshore working. Lol you can use my 6 yr old grandson for scale.

Went on a hunt with my son this past weekend. Had a friend join us for part of the day. We hit a part of the creek that does not get hit too hard. Was just telling her that I had found some large partial Cretodus earlier in this spot when she tells me she found a great tooth. She wasn’t kidding. Best tooth I have seen all year.

I found what appears to be a trilobite specimen in the Austin, Texas area. The fossil was found embedded in the bank of Brushy Creek in Round Rock, Texas that is in the region of Austin. I was told the specimen is unusual to this region and that no deposits in or around this area would support trilobite finds. Jess also told me that there may be people who would like to examine the fossil. I'm not sure how unusual the specimen is to this location but wanted to get some insight regarding this specimen. I'm not a professional and did use a week vinegar bath and a dreamel to remove most of the matrix. If anyone could direct me in the appropriate direction I would appreciate the help.

OK I thought the other two trip posts were getting a bit long. So I am creating separate post for the third trip for the Britton Formation in Collin county, Texas. The other 2 trips are here: I have to write these things in segments. I'm slow at writing sometimes since I write in between chores and such (i.e. other fossil hunting trips). Sunday I had a bit of time to work on writing the rest of the trip report. I was supposed to teach a couple scout badges this weekend outdoors, but wouldn’t you know it, it started raining. I thought I’d go hunting instead because the showers looked isolated, but when I looked at the radar future cast it looks like it will be raining much of the day across the whole area I usually hunt in. So I’ll work on writing the third segment between chores and cleaning fossils. I get so easily distracted. Here it is Tuesday and I'm just getting to post it I made a third trip out to the same spot with the Britton formation in the same week. Joe aka @Fruitbat and I had met at a local Mexican restaurant for dinner on Tuesday, I think it was. We live reasonably close to one another. When I met him for dinner I brought him a couple little slabs and a concretion of carboniferous plant fossils to play with. They were from my trip to Oklahoma at the end of April. During dinner we agreed to go hunting Saturday afternoon, provided I didn't get called in during the night and would be too wiped out to go hunting. I had told Joe I prefer to split the bill and pay for our own meals. He told me that his mother would roll over in her grave if he let me do that. I told him we would talk about that at dinner, trying to hold my ground. We did talk about it, but Joe is stubborn. While I was busy telling a story or talking or something the bill came and he took the bill before I thought to grab it and he paid for both anyway. I think I will either have to be quicker to grab the check or not go to dinner again unless the terms are agreed to up front. Am I being too modern or stubborn? I don't think so, but I am not a guy and I don't get how men think on these matters. I am trying to be practical and fair. I think its a generational gap. Joe is old enough to be. . . , well, lets just say older so as to not give his age away. I go to church on Saturday and the place is only 10-15 minutes away from my church. So the plan was I would go to church and then he would meet me up in a store parking lot near the spot we were going to hunt and we would go hunting from there. I was on call for my work. I have to stay within an hour’s drive of work at all times when I’m on call. I also have to have cell phone service wherever I go so my work can contact me. Believe it or not there are places within an hour of Dallas that I cannot get service at times. So this spot was as good as any I knew of within an hour of my work and I had great cell service there. I met up with Joe and we headed out to a construction dirt pile I wanted to check out first. I had seen it on the way to the spot last time. It was enormous. It was also part of the Eagle Ford group and probably less than 2 miles from the other spot. Sometimes I’ve found great stuff in construction piles. Sometimes they are complete duds. I'd classify this one a dud. This is a picture of the location. It was dirt taken from a new housing development right next to it. The soil was brown and there were a few plates of what appeared to be Kamp Ranch here and there, but the plates were pretty much compressed shell fragments. I'm still learning my formations. Been there, done that before. I knew there were better things waiting a couple of miles away, but I thought I would give the pile the once over anyway, just in case some gem of a fossil showed up. I guess I should have known that brown soil was probably not the best indicator for good fossils within the Eagle Ford. Maybe elsewhere. If anyone knows of brown soil in the Eagle Ford that has good fossils I'd like a little enlightening of what I might expect to find in it should I encounter brown soil in the Eagle Ford again so I don't completely discount and avoid it. I found numerous chunks of calcite and gypsum. There was the very rare very worn oyster and I found a few fragments of septarian nodules with the typical brown and yellow to white aragonite and calcite crystals in them, but these were pretty tumbled and worn down and not freshly broken open. After looking around for maybe 30 minutes we both decided that was enough of that. We headed out to the other location. We parked our vehicles. It was another blazing hot day. I had to convince Joe to bring something to drink. I was ready to put an extra Gatorade into my bag for him if he wasn't going to take one for himself. So he put one in his bag thankfully. It was over 90 degrees F. If you have read my other posts you know the issues with hydration I have had. I'm trying to turn over a new leaf. Plus the creek water out there didn't look quite so drinkable as the NSR water. That was sarcasm. The NSR is not so drinkable at all. I've come across places numerous times where you could tell the wild hogs had relieved themselves in the river by the smell. I still need to get me one of those Lifestraws. I digress. Back to the trip. We started the walk to the spot. This time I brought my rubber creek boots. They are the kind you get from Home Depot that the concrete pourers use when pouring concrete. So they can handle a creek pretty well, but they are a bit hot. We got to the place where the avalanche had happened and Joe wanted to explore the little creek below where the avalanche had happen. The small creek ran along the road. I can't remember if I mentioned that there were a few trees along the creek that had been taken down by beavers. One was one of the largest trees I've ever seen taken down by a beaver. It must have been over 12 inches in diameter. It made me wonder how many beavers died in felling trees. Within the creek there were some areas the water was shallow and the banks were high with lots of exposed rock and soil. I had explored it before. We didn’t really find anything other than the non-Cretaceous oysters. Just as we were about to the other creek where the hunt would begin I got a message from my work giving me a heads up that there was a deceased donor sample coming in for a pediatric, 2 month old heart transplant. I would need to go and work on that when they knew the ETA. I can't remember if I have ever posted my profession. I work in a lab and am a Histoccompatibility and Immunogenetics Specialist. I specialize in tissue typing for organ and bone marrow transplants and also for disease associations with the tissue typing. I have been doing that for 21 years in the same lab. Anyway, my work didn’t have the ETA yet they were just giving me advance notice. It had already been delayed twice. I was pretty hot and so bright I couldn't read my messages on my phone. So I found a shady spot to be able to read my messages. I sat down on the edge of a concrete slab poured to prevent erosion. It was a peaceful little place with the water running over the rocks. A tree was perched on the edge of the bank above me. I snapped this pic of Joe while I was sitting there reading my messages, replying and waiting for the response. We went on hunting while I waited to hear back on the ETA of the heart donor's tissue. Joe was the first to find something. He found a pretty little red ammonite about 1.5 inches across with a bit of matrix still on it. It was probably less than 30 feet from where Joe is in this pic. He offered it to me. I told him no way that it was his little memento of the hunt. If he found nothing else worthy of keeping that little beauty was worthy of keeping. I didn't get a pic of it. Maybe Joe can provide one. We continued with the hunt. I am not fast about covering ground while hunting, but I definitely move faster than Joe. Shortly after we got into the creek and began to hunt I got a call from the on call supervisor at my work telling me that the sample would be there around 6:00. That meant I had maybe 45 minutes left to hunt. We’d only been in the creek maybe 10 minutes max. Since I knew my time hunting would be cut short I was trying to cover more ground. I soon left Joe inspecting an exposure and moved on to another exposure further down the creek. I found a number of ammonite fragments. I found several halves of ammonites. Here are a few of them. The two ammonite halves were within 1 inch of each other along with the baculite fragment. I assume they are both Metoicoceras of some kind. Please chime in if you know what they are. I think this one must be a Placenticeras pseudoplacenta var. occidentale. Please help educate me if I am misidentifying them. I am very new at this. Sometimes I assume a species based on what I know is in the formation if it kind of looks like it. I am doing that with this one. I don't know of another smooth genus in the Britton. I also found a few more interesting bulbous concretion. Almost all of the concretion material are flat little slabs of rock not more than ½ to 1 inch thick, but occasionally you find little odd shaped ones or bumpy ones. I picked some of them up hoping I can figure out how to expose whatever may be inside. I found a few more baculite pieces. I found the longest fragment I had found. I also found a few tiny gastropods. Very cute and tiny. Here are pics of all the baculite fragments found over the 3 days. I am probably not the idea naturalist for combining the fossils from 3 hunts within a week from the same local. The largest fragment I did find when I hunted with Joe. This is one of the fragments. When it is wet it looks like shiny copper. When dry it looks like a metallic rose gold. It is lovely piece. I have a few others that have flecks of it on them. A few have a rainbow kind of hue. OK I am trying to break up my posts for this trip so I can include more pictures. Bare with me. More is coming. Oops left out a pic description. These are a number of the fragments I found that day with the exception of the Placenticeras ones.

My wife and I went to North Texas with the main lure being to collect on the N. Sulphur River. Since we were staying in Sherman we also visited Post Oak Creek. Lake Texoma was high on the list since we were so close, but prior posts about Texoma dissuaded us to " not take any chances ". At the time, people were stating the Lake Texoma Army Corp. of Engineers considered it a no-no regarding the removal of Ammonites from Corp. property. Since that time several years ago I have read multiple posts about collecting there but no caveats. We certainly have more trips to Texas from Missouri / Misery, and collecting at Lake Texoma would certainly be a destination. Set me straight...................

I got my hand on a Crinoid calyx from somewhere in Texas (no location attached other than creek), and I’d like to know if this should be prepped any more, and if it is worth seeking professional help (I certainly can’t do it yet). It’s around four inches (I think, it’s not with me right now). Thanks for any advice!

I found this jaw bone today on the Brazos River in Texas. It’s unlike any other I’ve found, I’m wondering if it’s croc or gator maybe? The bone seems to have the pock marked look I’ve seen in pics of jaws of those critters.
