    Fish jaw

    From the album: Fossils!

    Some kind of crusher fish jaw, presumably Pycnodont, collected from midra shale formation in Qatar, Middle eocene aged. Around 6mm in size. One tooth can be seen still embedded into the jaw. Might be the first specimen of this kind ever found here
  4. Hi everybody. Just finished up this little pycno yesterday. Cute little bugger. Less than 2 hours of prep for this little project. I used my new Zoic Velociraptor air scribe for this. A tool I've fallen in love with. Fixed up the crack that ran through the fish, squared up the rock with my tile saw and smoothed the egdes with my table belt sander and Waaaa Laaaa! I was not going to keep this at first and have decided to thin the rock in half and hang it onto one of my fish walls. Already have a spot for it. I also turned this small project into a video for youtube but it wont be out

    Pycnodont, Atco

    From the album: Austin Chalk

    Pycnodont, Central TX Coniacian, Cretaceous Dec, 2022
  6. At last week's NJ fossil show, I purchased one fossil, a cretaceous fish with an unusual feature. It is a Coccodus from Lebanon, its length is 6.5 inch (16cm) and dates to 95mya. Coccodus is a pycnodont, an extinct group of fish which lived from the late Triassic to the late Eocene. A pycnodont primary characteristic is molariform teeth, rounded and blunt, suitable for crushing shellfish amongst other prey. This specimen appears to be split with the dorsal surface exposed. What caught my eye is that most of the dentition appears intact, with a bones forming a maxilla and “palate” vault-like st

    Acrotemnus streckeri(?) Pharyngeal Teeth, DFW Coniacian, Cretaceous Mar, 2023
  9. Stick around, this one's a read but I'll try to make it fun. So, I have been to big brook last year, and While I enjoyed it, since I went in early feb, the ground was frozen which prevented me from finding much, as the brook was stingy that day. Nonetheless I decided to try my luck with Ramanessin as i heard good things about it. Because none of my family or friends could be bothered, I decided to take a day off work and drive 4 hours to the area and spend the night so I could get the most out of the location. what follows is the result of 2 days straight of fossil hunting. which I
  10. The weather's finally warming up here in DFW, and with that, it's time to move on from the comforts of dry land and return to the ways of creek stomping. These past few months, I've been mostly hanging around cuts and construction sites within the Washita Group, and to be honest, I've gotten a little sick of it. During that period, I steadily accrued a sizable list of potential Eagle Ford and Atco locations within the metroplex, and I was itching for the opportunity to finally go and check them out. Yesterday, I circled a few spots on the map and hit the road. Well, the first coupl

    Acrotemnus streckeri Prearticular Tooth, Atco

    From the album: Austin Chalk

    Acrotemnus streckeri Prearticular Tooth, DFW Coniacian, Cretaceous Feb, 2023 Some of the largest pycnodont fish to exist. Grew up to at least 1 - 1.3 meters in length.
  12. A couple of questions concerning these fish. Are all nursallia teeth characterized by the eight or so bumps on one side of the tooth? Did pycnodonts regularly shed their teeth? Most of the teeth I have found are hollowed out basally, which makes me think that they were shed, I have a few that look like they have remnants of jaw fragments attached, which makes me think that these teeth belonged in the mouth of a fish that had died. How do you tell the difference between pycnodontid and lepidotid teeth? Thanks!

    Pycnodont Tooth Plate?

    Hey everyone! This came from the same Ozan spot as my previous post. I found this little specimen on a gravel bar. I think it's a fossil, but it could be man-made... I'm really not sure. My best guess is a pycnodont tooth plate which would be a first for me. I have hesitations because the teeth are "holey" as opposed to little black bulbs. Maybe this is from weathering? Here are some pictures: Thanks for reading!

    Mystery Fossil Lumpkin, Georgia

    I have a real mystery fossil I found in 2004 from Lumpkin, Georgia. The formaton is the Upper Cretaceous Ripley FM. US 27 was being 4 laned and quite a bit of new material was exposed in the road cuts. I think I was within a quarter mile of either side of the well known Frog Bottom Creek Upper Cretaceous fossil site. I found Exogyra costata, Flemingostrea subspatulata, Pycnodonte mutabilis, casts and molds of gastropods and pelecypods,worm burrows, etc. The oysters have well preserved shells, and the rest of the shells are mainly impressions and casts. Originally I just glanced at the mystery

    Pycnodont Type Tooth or Coniasaurus?

    I found this tooth (2.75 mm length) while sorting micro-matrix from Post Oak Creek in Texas (Turonian). I had originally hoped this might be a posterior Coniasaurus tooth based on the more conical tooth type and root but have since found in publications that some Pycnodont tooth forms closely overlap posterior Coniasaurus teeth in general morphology. My guess would now be some kind of less common type of Pycnodont tooth form (the flat types are common in the samples) but I wanted to see what others thought.

    My Best Pycnodont Plate

    Most people don't know it, but besides my adventures in the realm of Paleozoic vertebrates, I also do a lot of collecting in the Cretaceous of West Tennessee and Northeast Mississippi. The Cretaceous of West TN is known for having a wide diversity of excellently preserved invertebrates (think Coon Creek Formation), but the vertebrate life is largely ignored. It mainly consists of shallow water marine reptiles, sharks, fish, and occasionally terrestrial animals. My collection consists primarily of marine reptile bones and a few teeth, but I have a small selection of fish, shark, and terrestrial

    Drum plate

    Edit: I've re-uploaded photos since Don made me aware that they were not showing up. I am able to view the photos from my laptop (a chrome book) and my cell (google pixel). Hopefully re-uploading will have resolved the problem. Hi all, Took a trip to NJ searching a cretaceous stream recently. Have to give a shout out and "thank you" to my new friend Tyler, whom upon stumbling upon me bumbling about in the stream, showed me the "good spot" where I can find better finds. Together, we found plenty of goblin teeth, crow teeth, shrimp parts, and myself, some nice pycnodont (

    Gyrodus circularis Agassiz, 1844

    The genus Gyrodus is a characteristic faunal element of Late Jurassic marine environments and includes the largest known pycnodont (G. circularis, Upper Jurassic of southern Germany). Most pycnodonts are small to medium sized fishes with a standard body length of some 25 cm or less. Only a few large forms with a standard body length of more than 50 cm are known. Gyrodus circularis is the largest pycnodont with a standard body length up to 200 cm (KRIWET & SCHMITZ 2005). References: L. Agassiz (1843) Recherches Sur Les Poissons Fossiles. Tome I (livr. 18). Imprimerie de Petitpierr
  20. Is this a lateral anomoeodus tooth? I have found a number of the medial teeth likely because the shape is more distinct but this would be my first lateral tooth. 3/8 inches. Thank you

    Great day in big brook

    Great day in big brook from 7am to 12 noon. Whole bunch of shark teeth including the biggest one I’ve found yet; 1.25 inch goblin plus a lot of John Snow teeth. A couple of pycnodont and a couple of cow nosed rays. One small enchodus and a couple of TBDs. Did also find one tick when I got home so be aware

    Several NJ Cretaceous Non-Shark pathologies

    Hello TFF, I got a couple items from the Late Cretaceous of NJ that seem to be pathological. The first one, an Anomoeodus phaseolus tooth, seems to be very wrinkly and so I deemed it a patho. That is more of a verification as I haven’t seen a pathological one before. The second is an Ischyrhiza mira rostral blade that has a third carina on one of its faces and a slight flattening (flattening better seen in person). This is also a verification as I just didn’t expect to see a patho rostral. The third one is a bit strange. It is definitely a fish tooth. T
  23. I had a few hours to hunt Lower Glen Rose in Canyon Lake, Texas area this past week. I enjoyed pleasant sunny weather and some unusual success. Nothing too rare was found. I spent 30 minutes at Leptosalenia texana zone finding the usual 3 echinoids plus a nice 20mm x 8mm pycnodont tooth (2 pics). At another site (where my first hunt yielded one crushed Pygopyrina & a few crab claws a few weeks ago), I collected one small deflated Coenholectypus sp. plus several fragments. I also found one fairy complete Pygopyrina, one Leptosalenia sp., one Parothopsis comalensis, two juvenile Hyposalenia
