  1. Could this be a new species of Ptychodus? I have never seen/found one this large before. If not, could anyone who is an expert in Ptychodus teeth give an ID? Thank you! It was found in West Alabama.
  2. I have been wanting to make it back to the Ellis County creek where I found so many teeth, but by the time I could do it, it had rained enough to raise the creek quite a bit. The water level has just now dropped again. I was working near Ellis County this morning, and when I finished very early, it seemed the perfect time to go back. Rain is forecast for this evening and the next couple of days that will likely bring the creek up again. Below is what I found that was either loose, or easily removed from matrix.
  3. Work has been interfering with both my cycling and fossil hunting time lately. I managed a day off today and started the day with a 30 mile bike ride. But there's a creek in Ellis County I've been wanting to hunt, and I really wanted to get my first look at it while the water is low. With Hurricane Laura bearing down on the coast, I decided to make that hunting trip today, not being at all sure how much longer the water will be this low. It's an Eagle Ford outcrop I went to in this creek. With my late start, it was 11:00 before my hike down the creek got me to the outcrop. I left at 2:00, so only had three hours for my first time exploring it. The temperature was in the 90's and the humidity was high, so it was definitely stifling hot. It did cloud up at times, and actually rained for a few minutes. But it was mostly just sunny and hot. The outcrop is the typical blue-gray clay you find with Eagle Ford.
  4. 8/16/20 Trip

    From the album Post Oak Creek

    Didn't find much this time. I don't think it's rained in a while - the water looked stagnant. Also was picked over well. Favorite find is the mostly complete Cretodus (found it under a fallen tree).
  5. Hi all- Today I led a group of Tate Museum members to a shark tooth site for a few hours of collecting. We had a good time and I think all 45 people found at least a few teeth, with many finding many more. Cretaceous shark teeth form Wyoming are not big. This site is one of the few I have found that I can bring a group to and there will still be teeth left after we leave. We had permission from the landowner to do this for a few hours today. At this site, it is somewhat easy to find teeth. It is much harder to find complete ones. I left all mine at work. These are the highlights of my wife's catch. Ptychodus is the most common species to find whole. There's one at the top right position. Here is the site. The highlight for most people was when a herd of elk trotted past us about 1/4 mile away. Oh, did I mention that a few ammonites were found... I did have an unpleasant encounter with a trespassing Harley biker returning from the Sturgis Rally. I am not a fan of bikers and this guy only helped strengthen my bad opinion of them. His travel buddy was much nicer and recognized me from TV, and managed to bring his friend back to the legal side of the fence. I work hard to build good relations with landowners and I do not want it screwed up by an arrogant "I can do whatever I want" {insert cuss word here}. Please get permission from landowners, everyone. The repercussions of not doing so get all of us kicked off of fossil sites. And if you ride a Harley... please be respectful. Hope you like the fossils.
  6. Ptychodus and others

    Found on 06/06/2020 Post Oak Creek, surface hunting.
  7. These were found in Grayson County, Sherman Texas on 06-06-2020. Found surface hunting. The two Ptychodus resting together were found about a foot apart. Perfect mates. i am relatively new at tooth identification. Please help to identify the other three large teeth.

  19. I’ve been walking over this every day

    Hello, first time poster - long time admirer. I moved to a new place and have been walking over this every day while getting exercise. What is it? KC Group, Middle Zarah Subgroup, Wyandotte Formation, Quindaro; aprox 4cm across at widest. This is in Kansas City, once the fringes of a great inland sea - so shallow marine fossils abound! It is located on the top edge of a natural bluff, enhanced by being an interstate highway cut, and is actually on the floor of an old stone quarry from the 1940’s - hence the probable erosion. At first glance I thought it the thorax of a trilobite, or an impression of one, but as it is the same color as the stone surrounding it, it just doesn’t seem to be right. I could use some knowledgable help. My guess is a ptychodus tooth - but I am way out of my depth here Thanks
  20. For anyone fond of Cretaceous sharks from the western Interior of North America, this paper is very cool and awesome focusing on Ptychodus. New Mexico MNH digital collection bulletin #81 https://nmdigital.unm.edu/digital/collection/bulletins/id/7316/
  21. Are these Ptychodus teeth

    Are these teeth from a shell crusher shark like the Ptychodus? Found in Greene county Alabama creek bed
  22. Can you find the shark tooth? (10)

    From the album Post Oak Creek

    I realize that a lot of my in situ shots are of ptychodus, but they seem to be more visible and photogenic. Taken 12/31/19.
  23. Ptychodus sp. Shark Teeth

    From the album Post Oak Creek

    One of my favorite teeth to find, Ptychodus was a large shark that likely feed on hard-bodied animals like shells, crustaceans, or maybe ammonites. Most of the teeth here are from P. whipplei but there are a couple that could be P. anonymus.
