  1. I know some of you find very complete nautiloids that are much larger but here in Texas they are often smaller and fragmentary, though the pieces can be well preserved and easy to extract from the loose shale of the Graham Formation at Jacksboro Texas. I had many fragments separated into boxes labeled "Pseudorthoceras" and "Mooreoceras" for smaller and larger segments respectively. Then I saw a paper that invalidated the latter genus, Revision of Some Common Carboniferous Genera of North American Orthocerid Nautiloids, Kröger & Mapes 2005, which made all of my specimens Pseudorthoceras knoxenses. This got me wondering what these creatures might have looked like whole so I started to gather a few fragments that might fit together in a continuous shell, including a piece with the protoconch and one with part of the body chamber. The result had one empty space which I filled with a clay reconstruction, then made a plaster mold from which I poured a plaster cast to fill the gap. I used super glue to hold everything together so I could take it apart with acetone if I wanted too. It may make a good display fossil for our table at local events though so I'll probably donate it to the Dallas Paleontological Society. The second section from the large end is the fake part. The rest are all genuine fossils from the same site but collected over several years, so not even considered to be associated. I'm pretty sure they are all the same species though. The whole thing is 38cm long and came out fairly straight considering what I had to work with..
  2. Took a little trip out to West Texas last weekend. My parents have friends who have ranches out near Balmorhea (great to have friends with ranches...everyone should have friends who have ranches!). I knew the general area was one I had wanted to go hunting for echinoids in the Boracho Formation (some very special echinoids not found in my area). I did my research on Google maps and the Texas Geology website, hoping I could pinpoint the right roadcuts! The first one we stopped at (I thought was the right formation) turned out to be a different formation, but I found some cool little brachiopods that are different than any i have encountered before and a couple of echinoids (phymosomas) and that was all for that little roadcut. Checked out a few more in the area but didn't find anything. Definitely didn't find what I was looking for! So on to our weekend at the ranch. The owner said he know of a "beach" on the ranch where "sea shells" were found. I was really surprised because on the Geology map it is all Igneous and Quaternary - nothing at all that looked Cretaceous fossiliferous. So we went driving around the ranch to the spot and to my GREAT surprise, we found an outcrop of Austin Chalk! I don't know how, but it was there! I found inoceramus clam parts and some of the most beautifully colored Exogyra erraticostata! So that was a really special spot! ( @grandpa -another "fossil that shouldn't be there!"- but it was!) The final day we were to head home, I convinced my parents to drive 30 miles further West before we headed back east for home. I knew there were supposed to be some more outcrops of the Boracho accessible so we took a little side trip and happily I found the formation I was looking for! And I was rewarded with a most LOVELY little Anorthopygus texanus echinoid! I initially thought it was a Coenholectypus transpecoensis (which was mainly what I was hoping to find -which I did not find!) but was happy to discover it was a more rare Anorthopygus! My mom found a nicely presereved Wahitaster wenoensis, so that was great too. I also found a phymosoma, but it's pretty beat up. A small section of a nautiloid and a nice bivalve which I think is a Lima wacoensis quadrangularis rounded out my day. So it was a good haul to West Texa! My best finds from Boracho /San Martine formation Anorthopygus texanus - 25 mm : Washitaster wenoensis 25 mm a not so great Phymosoma 1 1/2 inches Lima wacoensis quadragularis 1 inch From the Austin Chalk Formation on the ranch: Exogyra erraticostata 3 inches From the first roadcut which was Buda formation Kingena (Waconella) sp? what's odd about them is this "dip in the lip" so I am not sure what species it is (it is for sure Cretaceous Kingena/ Waconella and not a Pennsylvanian Composita which it very much looks like -we had a nice long post on that!) A few pics of some of the critters on the ranch: Auadad (not native, but gone native) Javelina mama and baby! A mule deer wild turkeys
  3. Two Ammonites and 2 Bone Pieces

    Hey Everyone, Needed to take some PTO due to everything at work. Those 14-16 hour days get to you after awhile. As is my normal I spent quite a bit of my mornings at NSR. Had quite a bit of luck. I found three things this morning I need help with. I was near the Bushy Creek meeting with the NSR. Some material had fallen from above. It was a mixture of the red matrix and a mustard color matrix. Actually quite a bit had fallen. Spent about an hour looking through it and found the ammonites and one bone. Smaller ammonite is reddish and fairly stable. Larger is the mustard color and very unstable. Only prep on either was with water and a soft bristle toothbrush. I am thinking Pachydiscus (P.) Paulsoni for them but something is off for me. Also, in one of the pics of the larger is that the shell fossilized? One bone reminds me a vert but the three things on the one side I have not seen. Other looks like part of a sheel fragment but have no idea what from? As always, any help is appreciated.
  4. Hey Everyone, I was wondering if anyone knew whether or not it is allowed to remove fossils from the Spring Creek in Garland, Tx. I have not found anything definite. Might just be tired though. Thanks for any help, Planko

  6. Unknown Humerus

    I found this distal end of a mammalian humerus several weeks ago on the Brazos River southwest of Houston. After hours of searching, it doesn't seem to exactly match any of the common suspects: deer, camel, horse, or bison. Deer or camel is more likely than horse or bison, as the bone is relatively slender and the end of it isn't as bulky as either of those animals. It is possible that I have incorrectly ruled out deer and camels as the trochlea and capitulum on the end are very worn down. If anyone has any suggestions, I'm more than willing to hear them. Thanks!
  7. Perissodactyl Astragalus

    Both of these astragali were found on the Brazos River southwest of Houston. The larger of the two clearly belongs to Equus, but the smaller one continues to stump me. I know by the shape that it definitely some sort of perissodactyl, and although it resembles the shape of the Equus astragalus it is much, much smaller. The taller of the two ridges (I'm not sure what their name actually is) on the proximal end of the bone has been worn down by water or time so that it seems almost level with the other. If it were still present, these two astragalus would probably be identical. It occurred to me last week while looking at it again that it might be from a three-toed horse since they were a lot smaller than the more modern species of horses that prevailed in the late Pleistocene. Is there any way to tell? Or is it just from a younger Equus individual? Thanks for the help!
  8. Need help with ID please...

    I’m in the twilight zone apparently...I know how ridiculous this seems, but the only thing I can find that remotely seems to match this thing for size and shape is titanaboa. I’m open to other suggestions. This was in my back yard in Fort Worth, Texas...relatively shallow - about a foot to the top of it. We are in a rocky area and are within 30 ft of the highest elevation in the county, about 150 ft above the average for the city. I can’t find a tape measure to put next to it, but measured with my iPhone and it’s 29” long, 13” wide, and about 9” at the highest point. Seems to weigh in the 80-100 lb range. It looks like were other At least 2 other snakes on top of it that you can make out on the top left of it, but pieces of them have broken off as well as some of the main specimen. The underbelly is in excellent condition...it seems clearly show “snakeskin”. It wouldn’t let me attach more pictures, but on the back you can clearly see vertebrae at almost the center position and what seems to be some other type of nerve endings above that. There are literally hundreds, maybe thousands of pieces in the immediate area from ground level down ranging from quarter sized up to basketball sized with most between golf ball and baseball. I’ve been digging slowly for 3 days with no end in sight. Many of them are hard to specifically identify but seem to almost all meet criteria for fossil and not rock. Please help...
  9. Howdy folks, Having trouble ID’ing this fossil. Im fairly certain it’s a cephalopod but I haven’t had much luck finding an ID. It’s of unknown origin but was found in Texas. It’s a creek fossil basically. I believe this is the side but I’m not certain. No finishing work has been done other than rinse and nylon brush. Opposite side with view of back Bottom?
  10. Legendary Week

    Two hunts, two creeks, two legendary finds in one week. I don’t know what you know about Texas weather, but in July it’s hot. Downright miserable, unsafe heat at times. Just a week and a half ago we hit a heat index of 111 degrees. So when you have a day that tops out in the mid 90s for a high, you take advantage of that cool front. I checked the weather and saw that Tuesday had a high of only 94. I messaged my buddy @sharko69 and said, “Hey, its gonna be a nice day. Let’s do some hunting this afternoon after work.” So we meet up at our usual hunting spot and he shows me a new drop in that I had yet to explore. So we drop in and right away I spot a Ptychodus whipplei tooth coming out of the wall. Woohoo! I’m on the board! Not a bad start. So we head upstream walking through knee high water, boots sinking in the silt, and the occasional game of limbo as we climbed under fallen trees. All the while taking great caution. On his scouting trip to this spot my friend saw a slide mark on the muddy bank. Was it crocodile or beaver? A crocodile in a creek in north Texas would be highly unusual, so we hedged our bets on the laws of probability. After all, fortune favors the brave right? Still I did desire to return home to my family that night, so we were on high alert. Then we arrived at our destination; the place looked almost heavenly. An enormous gravel bar stood before us, we knew it had to contain something wonderful, but would we find it? Fast forward to an hour later, the only thing I’ve found since my Ptychodus are mosquitoes. Oh and the breeze stopped, so now it’s hot-ish, humid, and still. But I’m focused and press on despite feeling like I’m in an oven. After a while I found another shark tooth. Squalicorax, one of my favorites. Nice. My friend and I are chatting and he walks over to show me his find, a nice Cretalamna tooth. As he leaves I scoot over to continue my search and right behind his steps lay a sight unlike any other. A black, deeply striated, and large tooth. I jump up speechless and throw my hands on my head. I turned away and had to do a double take. Surely I can’t have seen what I just saw. Yup, I did. A beautiful Pliosaur tooth was waiting right there atop the gravel pile. My friend sees my silent commotion and bolts over. He starts yelling, jumping up and down, and freaking out, just like I am on the inside. I gently pull it out and it’s in wonderful shape and it even has some of the root still attached. To put this in perspective finding a Pliosaur fossil here is insanely rare. While I don’t know the exact number I can virtually guarantee that the number of Pliosaur teeth found here in north Texas in the last decade is in the single digits. My friend found one just two weeks prior in the same creek and back then I thought I had seen the only Pliosaur tooth I would ever see. Boy was I glad to be so wrong. The rest of the hunt after that is somewhat of a blur. I found a few more shark teeth, a tennis ball sized piece of coprolite, oh and a smile that I’ll have to have surgically removed from my face. Fast forward a few days to Friday night. My friends sends me a picture of a monster 2-1/4" shark tooth he found from a new creek earlier that day. Wanna join me early tomorrow morning to hit up the spot some more? Pssh, does a fat puppy hate fast cars? Of course I do! So the alarm goes off at 6 am and I successfully beat the sun out of bed for today's hunt. After a cup of joe I hop into the car and begin the trek. We meet up in an empty parking lot, it looks like we're spies out for a super secret rendezvous or up to some type of nefarious behavior. But the only nefarious behavior that was happening that day was.... well actually none at all. Just a nice fossil hunt, social distancing style. We drop into the site and get to work. Unlike last time where I found something immediately we were held to a big fat goose egg for quite a while. A solid hour or more. "Boy I'm not finding anything." "Yeah me neither." 30 seconds later i hear behind me, "Oh heck yeah!" I turn around to see my buddy holding a nice segment of Mosasaur jaw. Missing the tooth sadly, but a heck of a find nonetheless. Well, it's good to know that they're out here, but I just can't believe they're all scurrying away once I get close to them. So I continue to search. Fun fact about my buddy @sharko69. He is a master Ptychodus hunter. He's so gifted in fact, that I have accused him of selling his soul to the devil. And that in return he was given the power that whenever he walks by a Ptychodus tooth, it just hops up into his pocket. The verdict is still out on that accusation. So he tells me, "I have yet to find a Ptychodus yet here." So they must not be here, it's the only logical explanation given his power. So imagine my surprise when I looked down and saw a gorgeous Ptychodus latissimus tooth. I'm not getting shutout today! Whoop whoop! We press on and for another 30 minutes, nothing more is found except for a ton of broken and busted up septarian nodules. These dirty rotten tricksters are littered all over the creek. They constantly tempt us into thinking they're something cool, only to be let down yet again. I look down towards the water and see what looks like another septarian nodule. "Not fooling me this time" I say to myself. I look away, but as I do I instantly stop and look back. Something seemed odd about that one. I approach it and I freeze. I say out loud to my buddy who's standing next to me but facing the other way, "There's no way this is what I think it is." He turns around and shouts out, "YES IT IS!" I reach down and pull it out. What I hold in my shaking hands is a stack of associated Xiphactinus vertebrae. 2 complete vertebrae, half of a third, and a tiny piece of a fourth. They're resting nicely in a perfectly flat piece of matrix, almost as if mother nature herself carved it out for a perfect display base. The rest of the trip continued uneventfully for me for another couple hours. Yielding to me "only" an additional Squalicorax tooth. On the way back my friend pulls out yet another 2-1/4" tooth. His fifth tooth near or above the 2 inch mark in a week. (I meanwhile have yet to join the 2" club, but it's something I'm working on). At least with this find I can confirm that he is not bringing them from home and planting them and is indeed finding them. So that capped off a week in which I found two legendary once in a lifetime finds. It was a fun week filled with mild-ish weather, fun times spent with the Prince of Ptychodus, and brilliant one of a kind fossils. But I think the greatest treasure of all, was that of the deeply forged bond of friendship through the medium of fossicking. TLDR; Found two cool fossils.
  11. Hi everyone! Well, I am completely in love with hunting micro matrix I got some Mineral Wells matrix and am having a blast finding the littles. But a few things have me flumoxed. Any help would be appreciated on ID'ing these things. All of these are tiny - 1/8 to 1/16 inch (2mm-4mm) Thanks so much!! Many of these "claw" looking things. If they were from the Cretaceous, I'd say they were Crab Claws....but Pennsylvanian I don't know. Are they crinoid spines? I have a variety of "typical" crinoid spines which look nothing like these: 1. 2, 3. "Club" looking things. Again, I'm assuming some part of a Crinoid? 4, "Arrow shaped" things....crinoid? And if so, what part? 5. 6. Weird "seed pods". Found at least 4 of them. I haven't tried to crush one, perhaps they are actually modern seed pods? 7. The weirdest one of all - "the bat" 8. And this thingl 9. Lastly....are these Arixtotles Lantern? Echionid Mouthparts? 10 . 11. 11 THANKS FOR LOOKING!
  12. Texas Cretodus

    Have done a bit of hunting at my local creek system that is very close to where I live and have been fortunate to turn up a few large complete Cretodus over the last couple of weeks. Largest are 57mm and 56mm and we’re found just a hundred feet apart two days apart.
  13. So, this title might be a bit of clickbait because unfortunately I have yet to find any actual shark teeth, so bear with me. I've visited the Whiskey Bridge site just west of Bryan, Texas several times now. The clay-like matrix that makes up the north bank of the Brazos River under the bridge has several layers of fossiliferous Eocene deposits, and although I've found lots of coral, shells, and even some cuttlefish prongs by surface hunting, I've had no luck when it comes to shark teeth. Assuming that the only way to find small dark-colored teeth amongst a bunch of dark-colored dirt was to take a lot of that dirt back home and go over it out of the hot Texas sun, I picked up a couple gallons worth of matrix on the last trip and I've been treating it with mineral spirits and boiling water over the last three days so that I can sift through it. I'm about halfway through it all now, and I still have not found any. Anyone that has been to the Whiskey Bridge site before, can you help me out? Am I not looking in the right places? I heard somewhere that the teeth collect lower down the cliffside because they're heavier, but when I checked there weren't any fossiliferous layers in that area. This whole ordeal is starting to irritate me because I know that what I'm looking for is there - one of my buddies even found a nice handful of decent-sized teeth the last time he made the drive up to the site several years ago. Anyway, thanks for taking the time to listen to me, and if anyone has any help or words of advice they'd be greatly appreciated. Thanks!
  14. Mammal Calcaneum

    Found on the Brazos River just southwest of Houston. I know this is the distal end of a calcaneum, but I can't figure out whether it's horse, bison, or even bear - it seems to both match and not match pictures I'm finding online. Any help is appreciated.
  15. Hot Texas Creek Hunt!

    I hunted a remote stretch in Northeast Texas and found a nice variety of items. The vert is from a good size mosasaur. The sawfish teeth always seem to be broken. I found some small shark teeth and a piece of cretaceous turtle shell. The bottles are from the 1930's and 1940's. I really like the Groves Tasteless Chill Tonic bottle. I posted a little info on the old bottles. We saw at least twenty wild hogs in one pack crossing the creek and one giant solo wild boar.
  16. I've been finding Pleistocene fossils along the gravel bars in the southernmost section of the Brazos River lately, but they've almost always been unidentifiable chunks or fragments of bone. Obviously I'd like to find something well-preserved enough for me to be able to do the research and find out what it actually is, but I don't know where to look. The Beaumont and Lissie Formations that run underneath Houston and the surrounding areas are both Pleistocene-age, but the actual river basin itself is just made up of alluvial deposits. Of course, this must mean that the fossils are being washed down with the current from some location further north, right? The Waco Mammoth site is several hours from my location, but I know that the fossils there were found only a mile or two north of the river itself. Originally I thought that this is where the fossils I'm finding must be coming from too, but I know that Holmesina, Bison, and Camelops skeletons used to be found in the bayous within downtown Houston before the city grew to the size its at today. As far as I know, there aren't any exposures of sediments like this that are also the age I'm looking for anywhere close to where I live. I'd really appreciate it if anyone with experience hunting southern or central Texas could point me in the right direction. I'm not asking for any specific sites since I know people won't want to give those up, just general areas where Pleistocene outcrops or exposures would be present. Thanks for the help!
  17. Big rock covered with round nodules?

    Ran across this rock on the Brazos River near College Station, Texas. Covered with round nodules. Dimensions are about three feet by two feet by 18 inches. Any ideas what it is?
  18. NSR Unknown 7-19-2020

    Hi Everyone, As I am going through my bat with poison ivy I am taking the time to go through some findings. I have to pieces I have no idea about. Both found NSR. Any help is appreciated.
  19. It has been a while since I did an Echies of Texas post...too long!! But it's been an echinoid dry spell here for me.....I've found some lovely stuff, but just not anything NEW to me! I was given a couple of Echies that were new to me but I didn't TECHNICALLY find them, so they don't really count (for me...i'm particular that way!) . I will post pics of them because I am happy to have them in my collection regardless!! BUT, back to my personal urchin drought. . It's getting hot in Texas (Summertime...duh). But I still like to get out occasionally. I went a little further afield last week (only taking short day trips during this Covid Time) than my usual hunting grounds and found a new spot of Glen Rose Formation and found....AN URCHIN NEST! I've heard about these...a clump of multiple echies in one spot. I was too excited about my find and forgot to take pictures but there were five phymosomas in one spot...big ones too! And then a little further along....my first Tetragramma from the Glen Rose Formation! YAY! Drought broken! And, when it rains it pours. A few days later at another Glen Rose spot...i found more Tetras. And....I am pretty sure....a Polydiadema! So, needless to say, my Echie Game is back on. There are quite a few specific urchins that are still eluding me and not for lack of trying! I have been to the only spots I know of that I know they have been found, but alas. So the search continues! Another recent find, not new to me, but a really nicely preserved Phymosoma : (from a site just up the road from the Echie "nest") My first Tetragramma from the Glen Rose: Tetragramma tenerum .....i think. The Echinoid "nest" (plus the nice phymo from the other site up the road) My biggest Phymosoma to date....2 1/4 inches Another Tetragramma from the Glen Rose: And I THNK....a Polydiadema! Plus a nice little Heteraster with good detail Plus - My "acquisitions" to my collection thanks to my Fossil Friend John (who so kindly gave them to me!) An amazing Paracidarid (Glen Rose Formation) And a Globator parryi bottom of Globator:
  20. Cretaceous Coral Fossil?

    I was recently sent pictures of something that I am having a hard time identifying online. It was found in a creek bed of Cretaceous age, shallow marine limestone and marl on the west side of San Antonio, TX. It has a section that looks like it was attached to something. It does react to HCL and my initial thought was some sort of coral, but it has a very strange texture. I have seen a number of different types of coral, but never something like this and can't find anything similar. Any ideas? The closeup images of the texture were taken with a USB microscope.
  21. Osteoderm?

    Found on the Brazos River southwest of Houston, Texas. I originally thought that this was an alligator osteoderm, but it lacks the distinctive boss in the middle of the bone. Looking around on the forum, it seems to match tortoise osteoderms rather well. Can someone confirm? I've found carapace fragments from both hard and softshell turtles before, but never one of these. I didn't even realize tortoises had osteoderms until now. What part of the body do they come from? As you can tell from the pictures, the bone is a decent size, so would this have to be a giant land tortoise or something else. Honestly, I'm pretty out of my depth with this one. Also, if someone could recommend any sort of books I can use to help identify the Pleistocene fossils I find in Texas, that would be appreciated as well - it's starting to seem like the Florida guidebooks on the subject are going to be the closest I can get!
  22. My 5-year-old son and I found this giant fossil in a shallow creekbed near central Austin, TX, yesterday. It's about 10 inches in diameter and we think it's an ammonite, though it's very worn and we're not totally sure. Would love any thoughts! Thank you so much!
  23. Hey Everyone, Has anyone found a Eutrephoceras dekayi from NSR? If so, was it only 2mm or smaller in size? I really want one but man my eyes will have a hard time finding it. Planko
  24. Jaw Piece Identification

    Hello all. Going through my pickings from a couple weeks ago. Might be tough but wondering if anyone knows what species this might of come from. Roughly 1.5 in by 2 inch.
  25. I kayaked for five miles on a day with a heat index of 108 degs and found some killer stuff. The Paleo Dalton point made my day. Rare to find mosasaur in this creek but I still managed to find a few verts. The big nautilus was beat up but looks good in my rock garden. The old bottle is a duraglas bottle from 1953.
