  1. Post Oak Creek 11-18-20

    Here are my finds from my latest POC visit. Made a decent haul with my best Ptychodus yet and my largest tooth so far here. The tooth was about 1.5 inches. I also found a small ptychodus with no root but it did have very defined grooves. Pictures 2 and 3 are the large Ptychodus and picture 4 is the 1.5 inch tooth. 5 and 6 are the small Ptychodus. Picture 7 is the creek wall matrix I was looking in for teeth and 8 and 9 are the actual teeth I found in the matrix. Does anyone know if this is original matrix? I was able to find several teeth sticking out but several of them were also just pieces of teeth, like you find on the gravel bars, and not complete intact teeth. I was hoping if they were from the original matrix the teeth would be complete. And Finally I have a game for you. See if you can find the tooth in picture 10. For some reason many of the teeth I found this trip were highly camouflaged haha. The rest of the pictures are just closeups. I initially thought I found some mosasaur material but the bone feels modern to me now that it is dry. I also found my first vertebrae this trip. Looking at the other posts it seems like verts and artifacts are pretty easy to find but I guess I just don't have the eye for them as I have only found this one vert and have never found an artifact. Enjoy. 1. 2. 3. 4. 5. 6. 7. 8. 9. 10. 11. 12. 13. 14.
  2. Post Oak Creek November 2020

    Here are some finds from two trips in early November. Several ptychodus with one nice large one, a ton of shark teeth shards, a couple pieces of mammal enamel, and some unknowns. Im posting the shark teeth first and then will post the pictures of some of the others. Let me know what you think. Anyone know the species of the teeth in picture 1? I was specifically wondering about number 3 from the first picture. Pictures 6-10 are closeups. 1. 2. 3. 4. 5. 6. 7. 8. 9.
  3. Hi everybody! Last month i saw this tooth on sale and it was love at first sight But from the beginning i understood that what it was and how it be presented are not on the same page... Luckily i know the seller pretty well and we trust each other...so i asked info before make the purchase...He told me that his provider (directly from Morocco) told him that the tooth was a Dyrosaurus phosphaticus but that he was not confident about the ID...the moroccan provider told to my friend/seller that was the first time that he saw a totth like that and its first idea of ID was D.phosphaticus. So provider was not sure, the seller just report the same ID given by the provider...and after hearing this story, i was even more convinced that i was on the good path...this is NOT a D.phosphaticus tooth...but for me, it was not a crocodilian tooth at all. Then i started to wondering what could it be...and i have reached two possibilities: 1) Spinosauridae: like Baryonyx/Suchosaurus 2) Pliosauridae: like Liopleuridon or Simolestes The specific features of the tooth (well conserved on labial side, damaged on lingual side, full carinae, intact root) are: - 2 marked, smooth carinae - 9 labial ridges - less evident lingual ridges - smooth enamel Other info: Origin: Khourigba - Morocco Age: Maastrichtian - Upper Cretaceous (doubtful) Lenght: 5.5cm / 2.16 inches What do you think about it? Someone can recognize it? Let me know and thanks to everybody!
  4. In the last couple of months my son and I have purchased some unprepped Lebanese fossil fishy's. There are four known species of guitarfish from the Lebanese provinces of Hakel and Hajula. Rhinobatos maronita is one of these; this species was fist described in 1866 by Pictet and Humbert. Some purty dang cool stuff but the guy we are buying from does not know how to wrap and send fossils over seas! Our last shipment came in many pieces! Not good. My son is working on him to make it right? Aside from that Im going to do what I can to fix things. First up is one side of what I think is a Guitar Fish, Rhinobatus? My son purchased this and this is the 'not so good side' with the other side being in better shape. Every so often I will be back and make more post of these realy neato fossil fishy's. @oilshale I dont know much about the types/specimens of these fish from Lebanon so if anyone wants to chime in and correct me, I would greatly appreciate it. Thank you RB The back half of this slap used to be in one piece!!!
  5. Part Two of my Post Oak Creek matrix finds. A fossil friend sent me 5 gallon bags of gravel and I have been slowing making my way through (one and a half bags done so far!) and here are some of my best finds. The previous post (Part 1) were all teeth - shark and sawfish and fish etc... This post is ALL THE OTHER STUFF. Here is a link to the first post in case you want to see the TEETH. My favorites- Crab Claws! Two sides of two claws - Size 1/4 inch More claws and maybe a fragment of carapace? Size: Claws - 1/8 inch and fragment 1 inch Vertebras - So many little Verts! These are my favorites: Shark Verts (Mostly?) Not completely sure about Top Left one...anyone know? It's oddly square. It's also larger - 1/4 inch The rest are 1/8 inch Fish Verts Size 1/8 inch Some neat Dermal plates. Pretty sure Top Left and Bottom Right are Turtle. The others are maybe fish and shark.... Size Turtles are 1 inch and the others are 1/8 inch More Dermals - Size 1/16 inch Sawfish Rostrals Except Bottom left...not sure what that is. Perhaps a tooth? Size 1/16 inch Other various things: Top Left I think if a Pycnodont tooth, (1/8 inch) Top Right is maybe a Sclerorhynchus tooth or rostral? (1/4 inch) I really don't know! But it is interesting! These two are each 1/8 inch
  6. T. rex tooth

    Can you spot this T. Rex tooth can't tell is there restoration or anything. Butte County South Dakota, USA Measures 4.06" long That's all
  7. Please help with some clues

    Hello, I found this inside a loose chalk boulder on the Eastbourne shore. Based on the colour of the chalk it appeared to be from the upper cliff levels, perhaps cretaceous levels.
  8. I made a trade with a fellow Texas fossil hunter - sent him some Central Texas goodies for some North Texas Post Oak Creek gravel. I was hoping to get a gallon bag to look through in my microscope.....and he sent me FIVE gallon bags full of just scooped up out of the creek gravel! So far I've made it through ONE and a half of those bags! It may take me the rest of 2020 and right on through most of 2021! So I thought I'd post some of the good stuff I've found so far. Starting it off with THE TEETH. There were some larger teeth, nothing great, no ptychodus, which I was hoping for, but the mini finds have been outstanding. I have tried to ID them but if I am inaccurate in any of them , please let me know! Here is Part Two: The most common teeth: Goblin shark- Scapanorhynchus Size 1/2 inch (13 mm) My favorite - Squalicorax Size 1/4 inch (6 mm) Pretty sure these are all Cretolamna but I am not completely certain. I know the top left on is Cretolamna appendiculata. Size 1/4 inch (6 mm) And then there are the shark teeth that do not look like your "typical shark tooth"! These are Cantioscyllium (Nurse shark) Size 1/8 inch (3 mm) (Top row shows front and back of one and bottom row is front and back of another) Another pair of really interesting odd teeth Top Row: Kiestus texanus (front and side) Bottom Row: Rhinobatos lobatus (front and back) Size 1/16 inch (1.5 mm) Hybodont Meristodonoides Teeth and an Enchodus Fish tooth Size : Hybodonts 1/8 inch and Enchodus 1/4 inch Finally. lots and lots of Sawfish teeth! I am having a hard time distinguishing between Ptychotrygon and Texatrygon, so I just put them all together: Size 1/8 (3 mm) except bottom right red one which is 1/16 inch 1.5 mm) Other Teeth - I think the bottom left round one is a Pycnodont? Size 1/8 inch More to come! Crab Claws and Vertebras and other stuff!
  9. I took advantage of the day off yesterday for Veterans Day to attempt to beat the rain with a quick stop at the Reedy Point spoils piles (Late Cretaceous; Mt. Laurel Formation) from the C&D Canal in Delaware. Unfortunately neither of those things came true - it began to rain about halfway through my visit and I collected there much longer than I expected. This was my first ever visit to the spoils piles since I have found very similar fossils before in Big Brook, which is a much closer drive for me. I didn't quite know what to expect when I arrived. What I thought were going to be large piles of dredge from the bottom of the canal turned out to be large fields covered in a layer of sandy gravel. Hence why my visit lasted much longer than I expected. For the good part of the morning and early afternoon, I scoured the area, mostly surface collecting with a little bit of sifting. I didn't find anything extraordinary, but the sheer size of the bivalve shells there was enough to make it a worthwhile trip. Notably I only ever found mostly complete shells - these bivalves must have been massive when alive! There were quite a few fossils easily found just lying on the ground Here are my finds: Gastropod Steinkern Pieces I found two types of bryozoan on shell pieces I was struck by the extent of boring by sponges (Cliona cretacica) on this shell I thought these worm tubes (Serpula implicata) were pretty cool, including one that extends from one side of the shell to the other side The largest belemnite (Belemnitella americana) I found was about 7.2 cm, which is large but not as big as the 11.2 cm belemnite I found many years ago in Big Brook Similar to the bivalves, some of the belemnites also exhibited traces of boring sponges
  10. Amphibian (Scapherpeton) jaw section?

    Hi everyone, I haven't posted an ID in a while as I'm at college and don't have ready access to my fossils to take pics. However tonight, through sheer coincidence, I noticed a recognizable fossil online after looking at the new discovery of an albanerpetonid amphibian preserved in amber. After checking if these amphibians had been found in the Hell Creek I see an image come up of a jaw identified as belonging to scapherpeton (a true salamander) and recognized some features similar to a specimen of my own which I had never posted. I found this small jaw section in the Hell Creek fm. of North Dakota and while I don't remember a specific measurement I am confident that is was about 1 cm in length give or take a few mm. Here's the pic of the jaw I saw online, posted by the national museum of natural history on their google arts and culture page. Here's my small jaw:
  11. Brazos River--Large Turtle Piece?

    I found this partially covered in sand and very shallow water at the edge of a sandbar in the Brazos River near Brookshire, Texas. I cleaned it up with vinegar and a toothbrush when I got home. The fossils in the river near me are supposed to mostly be Pleistocene, but I've also heard that there may be some Cretaceous period marine fossils. I tagged this as a possible turtle piece because that's what it resembled to me, but I couldn't really find anything like it when I searched the internet and this site. I have more pictures, including pictures from before I cleaned it, if those would be helpful. It weighs about a pound. Any information would be great. Thank you! --Brandy
  12. Last winter, on an otherwise poor outing at Big Brook, N.J. in the cold, I found a partial ammonite body chamber- Trachyscaphites pulcherrimus with nice details. I showed it to Ralph Johnson, who curates the MAPS collection (Monmouth Amateur Paleontological Society). I agreed to donate this rare specimen to what is the largest collection of Upper Cretaceous marine fossils from the Atlantic Coastal Plain (New Jersey, Delaware, and Maryland). The fossil ended up in the MAPS collection's educational display. I finally got to see it today, prepared by Ralph, in the display case and photograph it.
  13. Post Oak Creek Micro IDs

    I have been able to identify most of the shark and batoid micro fossils I pulled out of the matrix I got from @Captcrunch227 . There a few teeth that I can not identify though so I thought I post them here. I think this 6mm tooth is a Paranomotodon tooth. It certainly appears to match the others I have and the examples on Elasmo. There is no evidence of any lateral cusps or anything.
  14. Texas Paleontologic Papers Available Online as PDF files Various University of Texas Bulletins, which are available online as PDF files contain in the form of Contributions to Geology, papers about the fossils of Texas. For example, there is: University of Texas Bulletin 4401, Contributions to Geology, 1944 University of Texas Bulletin 4401 contains papers about graptolites from the Cambrian of the Llano Uplift; corals from the Carboniferous of the Llano Uplift; Foraminifera from the Upper Carboniferous; vertebrates from the Triassic, Howard County, Texas; Cretaceous crustaceans from Dallas County; and Pliocene vertebrates from the Texas High Plains. Also, there is University of Texas Bulletin 3945, Contributions to Geology, 1939, which contains Crinoids from the upper Carboniferous and Permian strata in Texas, Raymond Cecil Moore; F. B. Plummer, Univ. Texas Pub. 3945, Dec. 1, 1939, pp. 9-468 Graptolite Faunas of the Marathon Region, West Texas The Ellenburger Group of Central Texas Index to other University of Texas Bulletins and Publications Example of search for "ammonites" in University of Texas Bulletins Yours, Paul H.
  15. Bone ID help needed

    I found this 1.5 inch triangular piece of bone in Big Brook. I guess it to be too small to be identified by species. But I am hoping someone can give me some information. One flat side shows bone whereas the other almost has a stone finish. Most striking to my eye is In the 3rd photo (side view) the bone becomes much denser and darker as it gets closer to the flat stone-like outside? surface from photo 2. Any insights greatly appreciated. Thank you
  16. Paperclip shaped ammonite may have lived for 200 years based on isotope analysis of shells https://phys.org/news/2020-11-ancient-squid-like-creature-paperclip-shaped-shell.html
  17. Mosasaur Jaw

    Hello everyone! I just acquired this piece but the only thing I know is that it's a mosasaur from morocco and it shows the lower jaw and the pterigoid teeth from the upper jaw. Can any mosasaur experts here help me identify the species? I'm thinking of prognathodon maybe?. Also as far as I know it's not fake or composite but would be great if you could confirm it. Thank you very much for your help, very appreciated! Greetings from Spain.
