    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!
  2. Hey everyone! I thought I'd share a few of my finds from the past couple months and get yall's opinions. Over winter break, I went back home to North Texas and did some searching around Ammonite Beach at Texoma and the NSR with my family. At Texoma I had a nice time hammering out a few ammonites, collecting teeth, and surprisingly finding lots of smaller, pyritized ammonites that I did not expect to be there. The NSR was a bit slower, but I at least got a nice Squalicorax as shown in the pics below. Since school has started, I've been down in Austin. I've been finding the usual stuff, but the

    Shark denticle? Tooth?

    My faithful assistant and I found a clump of dirt/clay/rock on a creek bank by the airport. The creek has a couple long and steep hills that look ozan-ish. Well, I took the clump home and slowly wiggled it apart. That clump held a couple of small teeth, tons of tiny little shells, and this mystery object. It's less than 1mm and very tooth like. I can't seem to match it to anything. Ideas?

    Bony Oddities of the Ozan

    Following the brief rains from earlier in the week, I decided to make a return to my new favorite Ozan outcrop where I had previously found so many mosasaur vertebrae. Though I did not get to add any new verts to my collection, I did manage to come across plenty of unique fossils and artifacts that have taken up my attention for the past couple of days. One interesting thing I have noticed from this outcrop is its abundance of pyritic bony material among other pyritic fossils (including "rusty" exogyra shells + bivalves). Most of them are unidentifiable chunks, but a few have enough distinctiv

    4 Mosasaur Verts in a Day! Austin TX

    With the end of the semester approaching, school has picked up and I have been too busy to embark on many adventures. When my schedule finally cleared up one afternoon following a brief rain in Austin, I jumped at the opportunity to do a bit of exploring. One of my goals right now is to check out new parts of the creek I hunt on. Scanning through my list of potential spots, I decided to try and be the first one out to a very promising location. Like my previous hunts, this place ran through the Ozan formation, so my expectations were set on some nice Cretaceous specimens as well as the usual n

    Dinosaur Tooth from Austin, TX?

    My loyal assistant and I were exploring in area by the airport in Austin, Texas a couple days ago and we came across a head-sized shell hashy rock. I think we were in Maestrichtian rocks (corsicana marl?)and I found an unusual tooth fragment in the center of the crumbly rock. I also found several small shark teeth and a lot of little shells in the same rock. This tooth is interesting because of the size (1.5 mm long and .7mm) thick and serrated edges. Ok ok... I've come a long way since posting that tooth shaped rock last summer. Since then I've found a lot of teeth in Austin in 4

    Possible fossilized bone?

    The owner of this item picked it up in the vicinity of Austin, Texas because he thought it was a "cool rock." It is about 5 inches long and reasonably heavy. Too heavy to be a bone from something recent; it's definitely mineralized. But the shape, the visible cellular-like structures, and the rounded bit that looks like a socket for a joint seem to point in the direction of fossilized bone rather than "bone-shaped rock formation." We have not licked it (!), as it's been floating around a public school classroom as a pet rock, so I can't attest to whether it sticks or not, or if th
  11. My faithful assistant and I have been sidelined with covid. But we felt good yesterday so we decided to explore a creek in Austin, Texas that has some Eagle Ford Shale exposed. It was a sunny, warm afternoon, and a cold front would be moving in at night. At this location we've found quite a few teeth in the loose rocks strewn about. We're hoping to find mosasaur material but we've had no luck yet. Our goal was to get a bucket of gravel to search for micro-fossils. I suspect most of the teeth are eroding from the underside of a large rock slab in the creek. We think this
  12. Hi everyone! I'm a newer member to the fossil hunting community. I first started as a little kid, but have only really gotten into it over the pandemic as a hobby. I've done some hunting up around Dallas where I'm originally from, visiting famous spots like NSR and POC. For college, I'm currently living in Austin and have checked out a few nearby spots. These past few months I've been frequenting a local creek that runs through the Ozan layer and have been finding some cool fossils/artifacts. The items I am showing you today are collected from two places. The first assortment (lots

    Central Texas Teeth and Bone

    My faithful assistant and I did some exploring in the wilds of Austin, most likely in a patch of Eagle Ford Shale. Maybe 80m years old? We found quite a few rocks with a nice layer of shell hash. We found a lot of teeth within those rocks; some ptychodus and various sharks. But a couple really stand out. The first is a long tooth that appears to have a piece of bone above it. Not sure it they're related. The tooth is a bit more than an inch long. The next looks like an enchodus fang? I was thinking it could be a stem of some sort but it has a tapered shape a

    Central Texas Creek

    I went on this hunt about two weeks ago, but only am getting around to posting it now. It was a great day at a new spot close to my usual stomping grounds. I was hunting under a bridge the week before when someone walking the path next to it asked if I had any luck - his name was Leo, and we actually recognized each other as both of us have posted about some of our Austin finds on reddit before. (PS - pardon the picture quality, most of these are screenshots from video) He invited me to hunt with him at a spot of his on the same creek close by sometime. I wa
  15. Hey y'all, here are two finds from two different trips that I'm having trouble IDing 1.) This Ptychodus from the sprinkle formation ( a tongue of the Ozan here in central Texas). I'm not sure, but I think the sprinkle formation around here is Santonian in age (~86-83 myo). (Please chip in if you actually know - google is so vague here) I have a suspicion, but I don't want to count my eggs before they hatch for this one. Any ideas? 2.) What I suspect might be a Cretoxyrhina mantelli (not sure if I see evidence of broken cusps or not, so I included
  16. We met up with a new friend and explored more of a creek we found a few weeks ago. The area has a few clay and shale exposures, and so far we've found several small teeth from a couple different sharks. Today's finds include a turtle, a couple small teeth, a couple of ammonites, a couple pieces of bone, a possible Indian artifact, and a game camera. (We're working on figuring out who the camera belongs to so we can return it.) Not bad for central Texas!
  17. Hi all, before I post today's trip in fossil hunting trips, I'd like to know a little better about the ID's. This is a ll from a creek in Austin (central texas) that exposes the Ozan formation (aka the lower taylor marl here) Specimen 1) I'm fairly sure it's a mosasaur tooth, but It's oddly stout. It seems to have two cutting edges, but I'm still just not quite sure how to differentiate Mosasaur teeth from Pachyrhizodus teeth. Which one is it, and why? Specimen 2.) This jaw is likely very modern - i'm thinking Racoon, the only reason it made me curious is the she

    Eagle Ford mosasaur

    Last weekend was one I'll never forget... I've barely processed it, but now that I can be more coherent, here is the story of the mosasaur we found --------------------------------------------------------------------------- On September 11 & 12, I researched and found new fossil hunting area (to me), that exposed the Eagle Ford formation. I decided to scout it, and that scouting trip ended up being wildly successful. On the first weekend of
  19. I did some exploring by an area of Shoal Creek (Austin, Texas) that experienced a large landslide recently. I first tried Bouldin Creek but I stumbled onto a group of free-range city dwellers bathing in the creek. It was a bit awkward so I just left. The location I found on Shoal Creek experienced a large landslide resulting in exposed rocks. The area seems to be a natural drainage area so the rocks were moist and soft. It was cool to see the various shells eroding out of the soft rock of the landslide. My best find was a few beer cans from the 80's, a slab with some in
  20. Today was the best fossil hunt I've ever had. I feel like I say that every time lately, but it really is true. Today was attempt number three at investigating the Eagle Ford. Attempt number one, in Travis county, found me wandering into the Austin Chalk. I did get a great consolation prize though, in the form of gigantic segment of a Parapuzosia sp. ammonite. Attempt number two was in Williamson county - the Eagle Ford is rare here, only really exposed by housing development. For that reason, I was quite pleased to discover a permanent exposure with consi

  22. Here are some things I've had in the collection for a week or two but haven't ID'd yet. I'm starting to label my collection, so I'm trying to label some of the more obscure pieces as well 1) Water worn echinoid - from a creek in Austin, Texas on the Ozan Formation 2.) Piece of mammal enamel. Found on the same creek. I once found a piece of columbian mammoth enamel at this spot, and from that piece I'm going to guess that this is also mammoth. I'm basing that assumption off of the rough, textured backside of the enamel chip, which I was told to look for in Mammoth
  23. An assortment of interesting finds from our hunt today. This was in the late cretaceous Ozan formation (also called the Lower Taylor Marl, I believe) around the Austin area, in central Texas. I'd like confirmation or correction on some ID's 1) I'm thinking Mosasaur tooth for this one, but since it's small enough to maybe be fish, I'm checking anyway. If measurements end up being important for any of these, I can provide them. 2.) I'm thinking Cretolamna for this shark tooth, but it looks like the cusps have two peaks, which is throwing me off. Any thoughts?
  24. Yesterday was attempt number two at finding exposures of the Eagle Ford formation. My first attempt a month ago found me deep in the city of Austin, searching for the Bouldin Flags member of the Eagle Ford. I had to move upstream to avoid a large homeless camp, and found myself on the Austin chalk instead, where I found a large piece of a Parapuzosia sp. ammonite ( that trip is below) While definitely a memorable hunt, with a cool fossil to show for it, it was technically still a mission failed - the Eagle Ford still eluded me. So yesterday, i decided to try again, this ti

    South Austin, TX Bone?

    We found this bone in creek in south east Austin, Tx. It's a quaternary area, and the only other fossils we found were huge shells. This is a first bone my 9 yr old son and I found so we're super excited, and appreciate any help in figuring out what it is Also, my sons bedtime routine now includes us opening the fossil forum and reading though people's trip summary's or looking at the cool things to identify. I appreciate all those folks that contribute their knowledge, time, and patience to us newbies!
