  1. Jawbone

    From the album Post oak finds

  2. Skin? Hoof? Fat and Bone? Help..

    Ok, last one I promise. I have found a few pieces of these fossil bone fragments with an odd type of material attached to them. Rather odd texture, sort of bumpy. My first thought was some type of skin or hoof. I am puzzled. Any ideas? Found in Post oak creek, Grayson Co. Texas Lower Austin, upper Eagle Ford Gulf series.
  3. Beautiful Texas Tooth

    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.
  4. I am long overdue for a trip report considering I must have been to maybe a couple dozen places and hunted them since my last report. I’ll just give you a report on a new place I’ve been hunting three times. Repeat hunting at the same place is rare for me unless it’s the NSR. A couple weeks ago my daughter and I headed out to a spot in Collin County Texas that I had spotted on satalite images months ago that I had been wanting to check out. I had no idea what I’d find. I hadn’t looked up what formation would be there. I just knew it wasn’t the Austin Chalk of eastern Collin Co. Where I find next to nothing but clams. I found out the area was part of the Eagle Ford group. The formation was the Britton Formation. The trouble with finding sites by satellite images is that you can’t tell if it’s private property, fenced off or has “No Trespassing” signs posted. When I got to the spot I’d marked on the map there was a fence and no access. I looked for another spot nearby and it also was fenced off. While driving looking for a third access point a turkey crossed the road in front of us at turtle or I guess it was turkey speed. It was surprising, because there were apartments across the road and it was a fairly busy area. I did find an access point maybe a mile away. Yay! I’d been planning on the trip all week and kept checking the weather for the rain forecast, because rain was in the forecast. My weather app said it would be in the low 70s all week. I thought that was nearly perfect hunting weather and was looking forward to the adventure of a new place and possibilities. Saturday came and it was no where near low 70s! I realized I’d had my weather app set to where my family lives in NW Arkansas for some reason. It was 90 degrees, not the low 70s that I had joyfully anticipated. There was a little dirt road/trail at the access point where I parked my car. The road ran all the way to the designated hunting spot. I am not adventurous with my car though. I baby my car and treat her well almost any way I can, except I do load her with rocks and dirt, but she gets pretty regular baths and vacuumings. I’m glad I didn’t venture down the road in my car. The road ran along the edge of a ravine that dropped off quickly to one side. There was a steep embankment rising up on the other side. Along the road there were the remains of 2 mudslides that had occurred taking out the road in both places. There was no place to turn around either so if I’d gone I would have had to back out about 0.2 miles. I did check out the exposed material from the mud slides. The mud slide ended in a creek. The creekbed had a lot of layers exposed. The only thing I found was a variety of oyster that is new to me, but looked like it was from the Pleistocene or at least more recent than Cretaceous. I saw them along the road as well, but not in the part of the creekbed where I hunted. The road ended at a creek. Unlike many of the creeks I’ve been to in North Central Texas the access down into the creek was pretty easy at this particular point. The banks elsewhere along the creek were often steep hand high though. Traversing the creek was a different matter where the water was and where the soil was wet. It was the type of mud you sink can sink in. We got past the mud without sinking in it on the way into the place we were going to hunt. We headed up the creek. It opened up into a wide area where the actual stream trickled along the south side of the creek, leaving a wide open area that was largely free of vegetation. Where the ground was dry it was a soft flaky, and even powdery light gray clay in places. It was almost like bentonite. There were thin, flat and usually smooth, brick red concretions here and there in the creekbed that were coming from a sheet like layer 2-4 feet above the bed. The layer was in the bed in other places. There were multiple layers of red/orange concretions. Most of the concretion material was thin (1/2 inch) and flat and smooth. There were concretions that were irregular shaped, bumpy or bulbous. At first I took no notice of the concretions. There are ones that appear similar in the NSR, but nothing much comes out of them, but occasionally you’ll get something really good. So I thought these concretions were of similar nature. We walked along. There were numerous fragments of small baculites that averaged the diameter of a pencil and were 1/2 to 2 inches long. We came upon a concretion, which had split in two. It looked different so I picked it up to inspect it. To my surprise is was covered with little baculites! Squeal!! That’s my expression for excitement and delight. Later at home I realized it had at least 4 genus of cephalopods in it! I began to eye every concretion because I now understood that all the fossils were either in concretions or eroded out of them. I began to find more fossils now that I knew how to look for them. There were patches of whitish gray tidbits of stuff that appeared to have washed out of a different type and color of concretion of some sort, but I never saw where they were originating from. They were clusters of white fossils here and there. They were in a white clay like material. They kind of looked like coral or something. They were small, but look interesting. I haven’t taken the time to clean any of them to what is in them. We were only there about 30 minutes and my daughter, Gigi (short for Gisselle) started hinting at going home. She’s not the biggest lover of fossil hunting. Also, it was 90 degrees outside and she can’t take the heat very well. A few years ago she fainted on the playground at school from heat/sun stroke and she hasn’t taken heat very well since. We hunted 10 minutes more. While out hunting I came across this. It is a little over 2 feet across. You can see it on the right of the pic above of the red concretion layer and see how it stands out from everything else. It was very weathered though. Initially I thought it could be the remnants of an ammonite or something. I had no idea. I picked up one of the concretions, but didn’t see anything. It was pretty flat too and I doubted much could be inside so I left it. Over the next couple days I kept thinking about how I wanted to be certain about it. It went from large to small. So it wasn’t just random. So I planned to return before the end of the week, because we were expecting rain. There was quite a lot of evidence that raccoons frequented the creek. Piles of fish bones lay here and there. I found some pre-coprolite (scat) material left by raccoons. I thought the fish bones looked kind of cool. We see a lot of fish vertebra around these parts, but they’re usually only the central disk. It’s a good example of what some coprolites looked like before fossilization. There were fish bones and crawfish (crustacean) parts in the scat. I could tell my daughter was getting worn out by the heat. There wasn’t much shade in the area. I found a mesquite tree on the bank. We sat in the meager shade it offered, very thankful for the little it did give. We drank some Gatorade and rested a few minutes. Mesquites are not the best shade trees because they have very slender leaves and the foliage isn’t dense. Here’s a pic of mesquite leaves. I left her and my bag sitting in the shade for a bit and hunted nearby. I found more of the same. I found some fat little concretions that made me curious. So I picked them up to take home. In all I found the oysters that aren’t Cretaceous, and numerous clam fragments of at least 2 kinds, both Inoceramus genus I believe. Some fragments still had bits of the original shell present. They were a deep reddish brown. I also found a cool impression of an ammonite that looked a bit like Botticelli’s Birth of Venus clam shell or a soap dish. Sorry Botticelli for the soap dish analogy. There’s a clam I had found just above it. I found the fragmented remains of another ammonite. I found 4-5 of the baculite hash plates A couple were quite small though. One plate I picked up because of the large clam fossil on the top side. When I turned it over the other side was covered with baculites! I also found many baculite fragments all over the place. It is a rare thing for baculites to be the most frequent fossil found, but that was the case there. The place was winning me over one baculite piece at a time. Gigi got up and came over carrying my bag, ready to go. I told her I’d finish hunting this one patch of concretions and then we’d go. I split my last Gatorade with her for the trip out and rearranged our bags. I hadn’t come well prepared. My small collection bags were still full of fossils from my last trip so were were using plastic grocery bags that weren’t holding up well. I was certain there were more types of fossils to be found. I knew this was going to be a repeat local. Very few locals do I ever return to. Even if I came away with a good haul. A place has to hold the promise of further discovery of more treasure yet undiscovered for me to return again. The treasure is usually better quality or diversity of genus or species. Sometimes it is the trill of the adventure I have or how much of a challenge the place was for me. The NSR is my #1 favorite for the adventure and the treasure diversity as well as challenge. I don’t think it could ever get old for me unless it were to be developed or something. I do take family, friends or other people who are visiting to hunt at places I thought were good, but didn’t hold the allure for a 2nd personal trip. On my return trip out of the creek one of my feet sunk down in the mud about 8 inches. When I tried to pull my foot out my boot stayed. Needless to say I got quite muddy. My daughter got out unscathed by the mud. I’ve a wonderful daughter that is the greatest delight to be around. We were walking back to the car, I had mud all over me, I’m soaking wet with perspiration, it’s running down my face, my hair was pulled back to get it out of my face while collecting and it was matted down with sweat. My face was red from the heat. We stop in the shade of a large tree along the road for a short rest. She turns and looks at me and says “Mom, you’re so beautiful!” I’m thinking I look a pathetic mess, but she just sees beauty. I love that about her. She is such a blessing and delight to me. She has been that way since she could talk. She sees beauty in everyone. It’s like she has people specific rose colored glasses. She sees past the physical form of a person and to the beauty within, but within her eyes it translates to physical beauty somehow too, no matter how uncomely someone may be outwardly, she still sees beauty. It’s beautiful to see people and the world through her eyes. We finished walking back to the car and headed to Braum’s. It’s an ice cream, burger and fries kind of place with real ice cream, not just the soft serve. I always get mint chocolate chip ice cream and she gets chocolate. I have to sweeten the fossil hunting trip with something to make it worth it. So we always get ice cream after every fossil hunting trip. We went through the drive through of course since I was covered in mud and looking . . . “Beautiful” as Gigi said. I went back to the location 2 more times the same week. I’ll post stuff from the other trip.
  5. 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.
  6. I am doing the jury duty thing today so I have a lot of time on my hands to make a trip report post. This post isn’t rich in fossils despite visiting 3 different sites. It was something of a strike out for the day, with the exception of 2 pieces from the 3rd place we stopped at. One of the pieces was a true keeper for me though. I was on call for my work this past week, including the weekend, which means I have to stay close to home. I had a couple really long days without sleep. One 27 hour and the other 24 hours. It wipes me out. Thankfully I didn’t get called in Saturday night, because I had plans to go poking around a few spots with @Fruitbat aka Joe. He lives maybe 7 minutes away from where I do. The day was on the cool side, in the low 50s, overcast and breezy, but reasonably pleasant. The first place I wanted to check out was about 15 minute from my house. It was in the Austin Chalk, upper I think. I didn’t have high expectations of finding anything noteworthy, but I keep trying, because I’m surrounded by the upper Austin and upper Ozan, which have next to zilch from what I’ve on numerous attempts. The area we went to is a new development that recently broke ground in Garland on the southwest corner of Shiloh and Buckingham roads. It is mostly black clay like material, but a bit of white chalk and light gray shale are exposed and I think limestone or marl was exposed during trench digging. There is also the Duck Creek waterway on the east side of the development. We didn’t find much more than Inoceramus clam fragments in the development area. I did find an interesting looking clam about 1.5 inches wide imbedded in chalk. No clue what it is. Since we didn’t find anything there we headed to check out the large creek. It seems the city channeled the creek to bury water or sewer lines in it. So it was down to the bedrock with a concrete strip running down the center. The banks were about 10-15 feet high in most areas. The East bank being layers of chalk and marl like stuff. The west side dirt and clay. When I got into the creek I couldn’t find my phone. I assumed I’d left it in my car. Later I realized I’d put it in my coat pocket and had it the whole time. I didn’t get any pics. There was only one picture I wish I’d been able to take. In the creekbed we came across a circle that looked like a giant flat cinnamon roll about 2 feet wide. It didn’t look like any ammonite I’ve ever seen. Joe said it was an Inoceramus clam. I squatted down to have a closer look and sure enough the side was exposed revealing the tale tale pattern of Inoceramus shell edge. It isn’t the biggest clam I have found out hunting, but it was probably the most complete large one I’ve seen. I’m tempted to go back to take a pic since I drive by there most weekdays. There wasn’t much of interest otherwise. Since we didn’t find anything of interest we headed south to Dallas to our 2nd spot. I’d seen an exposure off of 30 I wanted to check out. It was part of the Eagle Ford formation. We arrived and parked our vehicles on the edge of a large field and made our way walking towards a hill in the distance with an exposure visible. There were huge piles of construction dirt and rock in the field. I have explored those before so I didn’t revisit them this time. Most notable were the very large septarian nodules with brown and while crystals. I’d been here before and collected a few pieces. We walked through high grass and underbrush then headed downhill only to encounter a wash or small creek we couldn’t cross. The creek doesn’t show up on any map. We worked our way along through considerable underbrush between knee and waist high along the creek. Joe took a little rest while I explored the area looking for a crossing. I found one a Joe soon followed. After crossing a couple of them I came to a dense hedge of Chinese privet. If you’ve never encountered it you’re blessed. If you’re considering it for landscaping think twice. While it is pretty it is a very aggressive shrub that grown incredibly dense making areas impassible. It will take over a whole field and thin forest if left unattended and nothing else can grow there. I didn’t notice it until I came to it and realized there was no getting through or around it. Here you can see a dense patch of it. It’s maybe 5-8 feet tall in most places. We realized there was no way to make it to the outcropping from where we were. We walked back to our cars after maybe 30 minutes of trying to get to the outcrop. We would have to come at it from a different direction. There were lots of spring flowers in bloom along the walk. I thought I’d share them with you. Per Joe this is a form of wild mustard. This is actually the bud of my favorite wildflowers. It is a milk thistle. I don’t like the prickly part, but I think they’re beautiful, but that isn’t why I like them. I like them because I am fascinated by them. I have picked them many times and arranged them in a vase beautifully. I leave for a few hours or overnight and they have completely rearranged themselves! Not just a little either. Individual stems will move by an inch or more at times. I think it is chemotaxis or something. It isn’t phototropism, because it happens at night and the direction they move is not uniform or unidirectional. Can’t wait for them to be in bloom. I don’t know what these are. I think these are 2 varieties of evening primrose. I think these are a form of verbena. We drove around the back side of a large warehouse and found a spot to park. We were able to access the exposure from there, but only because someone had bulldozed a path through the Chinese privet. Much of it was the Eagle Ford gray flacks shale. I found the top valve of an oyster or possibly clam (I still need to clean it up). I also found a very weathered fragment of a medium size ammonite that was only identifiable because of sutures. Other than that the only thing of interest was more septarian nodules. This is one of the smaller ones I saw. You can’t see the septarian qualities on the exterior, but it’s definitely a septarian. It was very heavy or I’d have taken it home to open up. If they have a split in it like this one they usually are filled with crystals. I also found quite a bit of small crystals laying around. Usually it’s calcite, but I’ve read the formation has abundant gypsum. Nothing of real interest there other than septarian nodules so we moved on to look for our third location. We drove west on I-30 and then south on loop 12. The first spot didn’t have anywhere to park nearby. So we drove across the freeway to look at an exposure off of a parking lot in a low area. I think this is likely to be the Kamp Ranch formation, a subunit that underlies the top layer of the Eagle Ford about 75 feet under it near Arcadia Park. This location was not very fossiliferous, but it did have yellow/orange thin plates largely consisting of conglomerates of shell fragments. It also had gray and black clay/shale with large septarian nodules. These are some of the fragments I picked up. This is one, which was buried that I tried to extract but I wasn’t successful. It was too big and I didn’t feel like putting in the effort needed to extract it or break it up. I walked around picking up plates looking for anything of interest. I came to a wash area and found this plate. This is the find of my day. It is covered with small ammonite impressions. It’s the only hint of ammonite that I found. There are a number of impressions that are partially covered up. I think with a little prep work it could be a real beauty. I’ll have to practice on the back side to make sure it doesn’t leave white marks. While I was off finding this Joe was off harassing this poor mama killdear bird nearby. He was trying to find out where the eggs were so we didn’t step on them. Turns out she was sitting on them. He said she was giving him the broken wing routine. She also spread her wings and tail trying to defend her eggs and nest. Her eggs are just behind her. Joe found this little plate and gave it to me. It’s got a little shark tooth on it on the top left. From there I had to leave to go home. It was a relaxing day, except for fighting through the little jungle like underbrush and vegetation trying to cross the wash/creek and having to retrace our path because of the Chinese privet. But it was a nice day overall. Oh, this is a closeup shot of part of the ammonite impression plate that I forgot to insert above.
  7. Cretaceous Shell

    Found this shell while in the creek this weekend. I have never found a shell like this in all my time in North Texas creeks so this seems out of place. Has matrix stuck to it and inside that matches what is present where I hunt. It is fossil and has some spots that look like calsite or some other crystal. Any ideas?
  8. Ptychodus Perfection

    Found this beauty a couple of weeks ago. I have identified it as P. atcoencis because of the chevron pattern but the crown is very low and it has more ridges then teeth I have previously found. Thoughts?
  9. Eagle Ford Possible Bone Fragment

    Please help my wife ID this possible bone fragment she found. It is symmetrical and it appears to be part of a skeletal bone that broke off at matrix rock's edge. The formation is Eagle Ford Lower Bouldin Flags shell hash layer. Found with small Ptychodus occidentalis and P. decurrens and multiple regular shark's teeth and some other smaller bone frags. Dimensions are 54 mm long by 38 mm tall and 16 mm wide at fracture tapering to ~1 mm wide. It is reportedly in the same layer that a 4" Tylosaurus tooth was found by another collector years ago - which does not match the biostratigraphic record.
  10. Invertabrate From north tx

    I’ve never found this in the Eagle Ford. ID please? upper cretaceous 86-90 mya
  11. Cool little find

    Found this little item last weekend while gathering gravel at Post Oak Creek. Anyone know what it is? Thanks David
  12. Brachauchenius

    Brachauchenius lucasi finds are more based in Kansas, but examples in Eagle Ford Texas have been found, most notably Willison's 1907 second B. lucasi skull which has been found in the same area. There is a possibility that this tooth could actually be Polyptychodon hudsoni which have been also found in Eagle Ford, but based on the morphology of the tooth (especially the root part near the crown), I think it is more likely B. lucasi.
  13. Claw??

    looking through some matrix tonight and found what looks like a claw. It is roughly 1cm long. Matrix comes from North Texas Eagle Ford Cretaceous. Any ideas? Thanks as always for help.
  14. Possible partial Ptychodus ???

    Found this this morning while going through some of the POC gravel I brought home last weekend. Whatever it is, it's a first for me from the POC. Looking online and in the forum, it sort of has the look of Ptychodus mortoni. Am I close or way off base? If I'm way off base, give me a break. I turned my thinker off once the work week ended. Thanks in advance David
  15. Septarian nodules sometimes are misidentified as turtles, coprolites and other fossils. Septarian nodules are hardened mudballs that dehydrate, crack and fill with minerals. The cracks in this one filled with fluorescent calcite. The ribs that stick out are the calcite that filled the cracks in the mudball. This nodule was found in calcareous shale from the Late Cretaceous Arcadia Park Formation. The exact age of its formation is unknown but probably occured in the Late Cretaceous. Septarian nodules from the Arcadia Park Formation are common in north Texas. Some contain spectacular calcite crystals when cracked open.
  16. I found a very nice variety of items while hunting my new favorite creek. I think the formation is Eagle Ford. I found a nice ammonite bed that I"ll start checking after a good rise. I had to leave the 50 lb + ammonite until I can get a boat or raft in there to float it out 2 miles. The old US military button was my favorite find of the day. The button is 1902 or later but still very old and makes you wonder how it ended up there? Two of the shark teeth are pretty big.
  17. Texas Cretaceous Fish

    Found this fish tail yesterday, and was wondering if there is enough here for an ID? Thanks
  18. Thought I would share some pics of these specimens I found a few years ago. Found them on the surface after a recent construction dig in the city. From the Eagle Ford Group, 90 mya.
  19. Hash Concretion

    This is from a Formation in the Eagle Ford Group of Denton County, Texas. It's only 2" X 1½" but it has a lot of fossils in that small space. I will do or get done a little more prep to make sure there isn't anything else in there but I'll keep it all attached. I think the brownish-red matrix is sandstone and it's pretty thick so I think it will hold together fine. Very little was showing when I found it. The close-ups are clockwise to the center.
  20. Not sure what this is ???

    Found the following yesterday while out gathering some gravel in Post Oak Creek. I know its not million of years old but it looks quite a bit older than I am. Any idea what this may be? Thanks in advance David
  21. New Ptychodus for the collection

    Going through a bucket I brought home last night I found this nice little Ptychodus tooth. Looks like P. mammillaris?
  22. I found this crystalline calcite replacement fossil mold after breaking open the width of a 2" to 3" thick Eagle Ford limestone layer loose fragment. The rock broke along the circular arc of the fossil mold. The mold is somewhat mushroom shaped with a small inoceramus clam attached to the side. It is about 4.25" wide. A full circular arc might be more than 6 inches in diameter. The mold appears to be fragmented and hollow on the top of "mushroom shaped" side. The narrower bottom of the mold also flared out a little, but not as much as the top. I think that the thin base layer cutting at 30 degrees to the mold is an oyster shell hash layer that it was deposited with - although at the mold top the hash layer to be unusually smooth faced. Some of the calcite mushroom lip broke out on the other fragment (the 4th photo shows it upside down on the bottom). The lip was not likely to be easily recovered. So, I cut that face of the limestone fragment back from the lip so that the two can fit together where you can still see the concave fossil surface inside. I worked off the convex outer matrix of the mold and the micrite limestone matrix until there was little else left but the mold. The oyster hash (or other) layer and the small inoceramus are also attached. The limestone layers in the outcrop area has some 15mm or less tooth width sized Ptychodus and up to 12 to 20 mm long cutter shark's teeth. There were also two ammonite molds (10" to 12") preserved in similar crystalline manner. There are a few shark verts and fish/ray teeth also. The few Paleontological Society of Austin folks I showed it to at the recent meeting could only see the concave face before I had carved it out more. They would not try to guess its origin. My first inclination was that it is a large vertebrate bone fragment. That might have been just well wishing. A giant inoceramus hinge plate or other large invertebrate (like ammonite or nautiloid) interior mold seems more likely. Any educated guesses? Thanks in advance for your time.
  23. Just found this bone out of the eagle Ford group in north central Texas. 86-90 mya. I'm guessing it's mosasaur or turtle? One end is broken off. 4 inches length. If so can we get a bone ID from it? Limb bone? Thanks for any help.

  25. Eagle Ford bone

    Possible to tell what this bone is from? Found in Dallas County.
