  1. I fossil hunted the lower limestone flag member of middle Eagle Ford Formation in Travis County, Texas USA yesterday. I came up with three nice finds. The first is a 130 mm x 75 mm section of a large ~2' diameter ammonite. Two pics included but it is difficult to make out. I think it is an EUOMPHALOCERAS genus, based on GEOLOGICAL SURVEY PROFESSIONAL PAPER 274-C 1955. Any different opinions? The second find is a 15 mm wide Ptychodus Occidentalis per Shawn Hamm's recent email help for me on a couple of 10 mm wide Ptychodus out of 8 total located ~1/2 mile NE from the subject area. Check out
  2. After nine months, I finally made it back to the Ellis County creek where I've found so many teeth. This is an Eagle Ford outcrop. The water level was much higher than I expected. It wasn't quite up to the matrix that holds most of the fossils, but high enough to make wading across the creek dicey, plus I didn't get to hunt most of the sand bars. This is the biggest fish vert I've ever found. Most of the fish verts I've found in this creek aren't in very good condition either, but this one is in really nice shape. As usual for this creek, most of the Ptychodus te

    Nothing extraordinary, but I found an area with several chunks of matrix with teeth in them.

    South texas fossiling

    I took advantage of the nice weather on my last couple days off and went to a couple sites around town, in no particular order here's the most interesting things I found. First a worn ptychodus anonymous tooth from the eagle ford shale. next what I think is a pachidiscus travisi from the basal pecan gap chalk and a half of a graptocarcinus texanus carapace from the buda formation in a location I had never found anything particulary interesting before. Quite worn but still recognizable And while normally one finds echinoids and ammonites in the georgetown this time I only f

    I went back to a new spot on POC and found the typical array of broken shark teeth, a few Ptychodus teeth, and some interesting items I'm not really sure about. Anyone have an idea of what the item in pictures 6-8 are? What about 9-11 maybe coprolite or a fossilized crustacean? The item in pictures 12-14 appears to be a tooth but with no enamel I didn't think it was a shark tip. It could also just be a piece of bone or something. Sorry for the poor picture quality of that one but I will take better ones of it later. Im pretty sure picture 15 is a rudist and lastly the item in pictures 16-18 I

    Brachiopod or Ptychodus

    Anyone please tell me what the heck this is at first I thought it was a brachiopod then I was like it might be a Ptychodus tooth what do you think I don’t not know where it came from. About 2 cm in length
  9. Good evening to all participants! I have accumulated a lot of local (from Ukraine) material - I decided to sort it out, and recurring fossils, or not of interest to me, offers you an exchange. Everything in the photos is one lot. Consists of: 1. Tile from Carboniferous period with fern print; 2. A fragment of the armor of a armored fish Podolaspis Lerichei of the Devonian period; 3. Tile with Silrian brachiopods and tentaculites; 4. Mollusk of Neogene; 5. A small fragment of a fossilized araucaria of the Carboniferous period with quartzite crystals; 6. 2 fragments of orthocer

    Here are my finds from my latest visit to Post Oak Creek. The first few pictures are of the shark teeth. Items 4-7 im assuming are part of a Mosasaur vertebrate? Items 8 and 9 are some type of mammal tooth. Not sure if it is modern or not. Finally item 10 is picture of what im assuming are modern mammal teeth. 1. 2. 3. 4. 5. 6. 7. 8. 9. 10.
  11. Cold day in the desert but a ton of fun with some great finds! Thank you @PFOOLEY for the wisdom. These all were found in the Carlile formation in Sandoval County, New Mexico.
  12. I'm a newbie who lives in the Austin area with a lot of passion for ancient life, but I'm having trouble making a decisive start with with my searches. I have a particular interest in large western interior seaway predators, most notably xiphactinus, but also the mosasaurs and sharks that lived in the area as well. Finding a vertebrae, of perhaps even teeth from these groups would be absolutely wonderful, but of the few creeks in the Austin area I've scouted, I've been able to turn up nothing besides gastropods. This is still despite heavily studying the sometimes confusing Texas geological ma

    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
  14. 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 a
  15. 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.

    Ptychodus Tooth ID

    This came from the bottom of the Eagle Ford formation in Texas, could even be the top of the Woodbine formation. Ptychodus lattisimis? last pic for scale
  17. 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.
  18. 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.
  19. 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

    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).

  22. 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.
