  1. I haven't had much time to hunt lately but I did manage to squeeze in a North Sulphur River creek hunt. My finds were not great but I did manage to find a nice variety. The fossil horse cannon bone is probably my favorite due to the preservation. It's solid rock. Lol my grandson carried it around the house all night when I brought it home. The Xiphactinus vert, old bottles and artifacts were a nice bonus to the usual Mosasaur material. This creek has some killer flint in it so I can see a nice arrowhead coming soon.
  2. Corsicana Bouillabaisse

    Buried in my prep bin I found a marl nodule from the Corsicana Formation that I snagged for the gastropod/bivalve association. Longing for the days before the site was built over, I pulled this thing out for prep. Well surprise, surprise! Beneath the Neithea bexarensis and Gyrodes rotundus was a Dakoticancer australis carapace completely hidden. I’m lucky I didn’t run my scribe through it while reducing matrix. The movable finger from the right chela is poking out from under the Neithea, but I opted not to blow apart the other fossils exploring for appendages. Anyway, it’ll keep.
  3. 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.
  4. Hemiaster wetherbyi

    I saw some construction in San Antonio near an old echinoid site of mine that has been covered up with asphalt and grass for over a year - Corsicana formation. I went Sunday for a hunt and got caught in the rain. I was able to score 8 nice Hemiaster wetherbyi de Loriol, 1887. Size 15.5 mm to 25.8 mm. I've never found one that small before. The cleaned up very nicely.
  5. Walnut with Wife: Part Deux

    And so my wife and I found our way back into the field today after the rain played out. The ground had turned to pig slop, but when chasing echinoids, I like it that way for enhanced contrast. Any advantage these old eyes can get is worth exploiting. This Phymosoma texanum was showing its good side for this photo. The other side was missing. No worries as we scored 9 high grade, perfect ones plus a score or more of high grade u-prep-m Heteraster texanus echs for gift or trade.
  6. Fossicking with Frau

    I got my wife out with me today for the first time in a few months. Decent pickings in the Walnut Formation. Engonoceras ammonites in this formation are usually pretty fragmented. This one still needs 5 minutes of scribe work, but it’s a keeper. Can’t hate on those sutures.
  7. So in late June early July my wife, 2 boys (8 & 2.5), my father in-law and mother-in-law and I are going to take a 2 week road trip around the US. We'll be leaving Maryland and heading down to Memphis, Tennessee followed by Nashville then on to Texas and ending up in Albuquerque, New Mexico at my brother-in-law's for a few days, then off to the Grand Canyon, up to Dinosaur National monument, over to Hot Springs, South Dakota to the Mammoth site, Mt Rushmore, and Crazy Horse Monument, then to the Badlands in South Dakota, and then start making our way back to home. We're taking some new paths and going back over some previous ones. I am interested in doing 1-2 hour fossil and/or rock and mineral collecting leg stretches not terribly far off US 40 between Memphis and Albuquerque. Honestly anywhere else near the places I listed and anywhere along US 90 back to Chicago and down to Indianapolis, then US 70 the rest of the way east towards home. I'm hoping if I ask on here I can get a handful of options for the trip, we may only do two or three depending on time, weather and general feedback from the rest of the family. I have messaged PFooley about the Albuquerque/Rio Puerco area. After we get back I will have to make a write up of the adventure, it should be a great trip full of geologic and paleontological fun. Thanks for any information, Adam
  8. Partial Tooth ID

    Found this partial tooth while hunting in N. Central Texas. Clearly mammal but not sure if there is enough to get an ID.
  9. Nautiloid

    Hello, I found this today in Austin Texas and was looking for help on a more definite ID. Ive never found a fully intact one, really good day. I was leaning towards paracymatoceras hilli. Thanks
  10. I have had these in my collection and just looking for a confirmation that they are the Pennsylvanian sponge Regispongia contorta from Palo Pinto limestone of Cisco, Texas.
  11. Could this be a fossil?

    This was found but we don't know if it is worth any looking into. The rock flipped up is what made him think it found be a fossil, and the discolored yellow throughout the rock from the one displayed to the bottom left screen.
  12. Could this be a fossil?

    Can you share with my how I can make my own post? I have been trying for an hour now and I wanted to ask if anyone thought this could potentially be a fossil find or a waste of time. That piece was flipped up but you can see the discoloration and such in the side of the rock continue on.
  13. Waco Pit Permits

    Today I called the Army Corps of Engineers to get a permit to collect at the Waco Pit. I was told that there is a limit on how many fossils you are allowed to keep. The limit per day is two. I thought anyone planning to collect there should know this.
  14. The Pliotoxaster comanchei is a common echinoid in the Glen Rose Formation of Texas. In the 1930's, there was a site for echinoids that is now under Lake Belton. Smiser in 1936 studied this material and described the echinoids as Pliotoxaster comanchei from the Fredericksburg Formation. Older names include Hemiaster comanchei (Clark 1915) and Palhemiaster comanchei (Smiser 1936). Last month I was found about 8 specimens in the Fredericksburg Formation, Bell County. Overall they are larger, and narrower at the bottom. I had never seen any others from the Fredericksburg other than Smiser's hypotype at the University of Texas. Has anybody else seen or found any specimens in the Fredericksburg? In the photo, the left is from the Glen rose and the other 2 are from the Fredericksburg.
  15. Unusual concretion.

    I know this is a concretion, but I think it is so cool looking. It has weathered so differently than almost any other concretion I have ever seen. Most layers of this type of material come off in a lot thicker layers. It is possible that is just how it weathered, but I am wondering if there is more to it than that. The layers are so thin and fine. I found yesterday while out hunting in a new favorite spot in the Britton Formation of the Eagle Ford group in Collin county Texas with Joe AKA @Fruitbat. The area I found it in is full of concretions. Many of them have fossils inside of them, but they’re a dark, brick red. The fossils are generally cepholopods, both ammonite and baculite, Inoceramus clams, other pelecypods and gastropods. This concretion is from a layer above the brick red concretion layer I think. I have concretions from all over. Some are cool colors and shapes and some have fossils inside, like my Mazon fossils and also Carboniferous ones I collected in Oklahoma. Also those that I’ve collected in the North Sulfur River and Britton Formation, but this one is unique it it’s own class. Any thoughts on it would be appreciated. It seems like concretions come up so often we ought to have a concretion section on TFF. Of course most of them come up in the fossil ID section. Anyone know the term for this type of concretion? I assume it formed by repeated thin layers being added on slowly over time, which now are eroding away. Thing is I didn’t find any others like it. I’ve been to the area 3 times in the last week. Why would just one concretion be like that? Side 1 Side 2 One of the long edges. The other is flat and solid looking rock, kind of like the bottom end of this one. End 1 different angle that looks a lot like wood, but must be just cool layering and weathering effects. End 2 the typical layered concretion look.
  16. Texas Mammoth Stuff

    I don’t buy fossils often as I prefer to find them myself. But I do respond to a good deal at times, especially when the specimens are better quality on average than my personal finds. Several years ago I met a husband and wife in a small Texas town with a mammoth jaw for sale online. The add was pulled due to thick heads at the sale site misinterpreting the ivory ban to extend to fossil ivory...fortunately this went down after we got each others’ Paypal info. Side note: I was first bidder and the new policy saved me from entering a bidding war! Anyway, I got a great deal, and they liked the no-haggling experience we shared. Every 2 or 3 years I get a call from them, as was the case this week. I guess they put the word out over time in their little town, and now everyone in town brings their unwanted Pleisto stuff to this couple for commission sale. We have a great rapport and they give me first right of refusal on everything. The stuff I don’t have room for I often give away as gifts or it makes its way into other hands pretty quick through trade or occasionally by sale. It’s all good...now my coworkers, friends and family are all loaded down by complete and partial mammoth teeth. And I may have kept a goodies few for myself. The funny part was watching me part with $ on this stuff several years ago. Now that I’ve found a few good mammoth teeth and tusk sections on my own, buying isn’t the same jagged pill it used to be. Glad my pride didn’t blind me to good deals. Anyway, let’s have a look at my most recent takeaways. The biggest tooth is 13” maximum dimension.
  17. Coleman County Texas Unknown

    Good Evening, All, My dad called me about some interesting fossils that his sister found on her son-in-law's ranch in Coleman County, Texas. They are quite strange. They are approximately 1.75 inches across, and are weathering out of hard limestone. I haven't seen them in person, only in the pictures that I'm attaching. The area is Permian, possibly Jagger Bend / Valera, though I don't know the actual location of the ranch. Anyone with any ideas? I'm stumped!
  18. I have 11 rocks that I believe contain fossils. Is there anyone on here who can verify if these are indeed fossils? These rocks were obtained years ago in Texas while oil drilling. They were found at approx 50-60- feet below the ground.
  19. Wood and...

    Found this while shark tooth hunting with my son but unsure what it is. Looks like petrified wood but has knots all over it. Any ideas what I have here? Thanks.
  20. ID: Large Dinosaur Caudal Vertebra

    I just bought a large, fairly well preserved vertebra from a rock shop in Tucson. It was found in the Aguja Formation in Texas, a formation that isn’t especially well researched. My diagnosis is that the vert is most likely theropod, and the only theropod that large that is in the area and comes to mind for me is the Acrocanthosaurus. This diagnosis is leaving me skeptical. Acro bones are pretty rare to my knowledge (there are only 5 articulated specimens discovered as of now), and I don’t see any documentation of them being found in Aguja, though as I said before it is not well researched. My only other theories are that this is from a Kritosaurus (which seems unlikely based on the size and shape), or that it is some other saurischian that isn’t documented in the formation yet. If I could at least get verification that it is theropod that would be very nice. This purchase will either have been a pretty good deal, or an absurdly amazing one. We’ll see, and thanks for helping! Bone is 6.75” long, 4.5” wide at widest point, and 4.75” tall at tallest point.
