  4. Thought I would share this little guy. Wife found it on the shores of Lake Texoma on the border of TX and OK. Latissimus?
  5. I explored a new creek spot on the North Sulphur River and had a good day with a nice variety. The Native American pottery and artifacts were a nice surprise at NSR. I rode over to Post Oak Creek only to find my favorite spot posted so I explored a new spot for one hour and found a few nice teeth.
  6. Found this interesting piece the other day at the north sulfur river. The overall shape reminds me of a couple of the larger Ptychodus teeth i have but the texture looks completely different. Looking forward to some input. Thanks!
  7. Little Ptychodus Gem

    Found this cool tooth in matrix while hunting with my son this weekend. Not a lot found in matrix where I hunt so cool addition.
  8. My wife and I found five Ptychodus latissimus from the same small pocket in the Atco Member basal conglomerate in the last seven months here in Travis County, Texas USA. I am pretty proud of these finds given the rarity of the teeth.
  9. Hit the creek for a while. It has been hit pretty hard since the rains a week ago and the holiday traffic. Found the usual potpourri of pieces and parts and found four very worn Ptychodus right off the bat. Luck changes as I work my way up the gravel bar. Found several nice P. whipplei including the largest I have ever found just over an inch wide. Found a beautiful small P. mortoni and a sweet complete S. raphiodon. I also found what at first looked like a Ptychodus shard but when I got home and cleaned it up, I believe it is a small piece of coprolite. Weather couldn’t have been better. 60 degrees but creek was still frozen solid in shady areas. Had the place to myself the entire time. Still looking to add a couple new species to the collection. So far five down.
  10. Ptychodus Perfection

    Found this beauty a couple of weeks ago. I have identified it as P. atcoencis because of the chevron pattern but the crown is very low and it has more ridges then teeth I have previously found. Thoughts?
  11. For all you Ptychodus lovers

    You Ptychodus tooth lovers are REALLY going to like Shawn Hamm's new article on an associated Ptychodus mammilaris tooth set from Kansas! Check out the link in my pdf library: LINK. (Shameless plug!) -Joe
  12. I went to Post Oak Creek in Sherman, Texas today, and I found quite a good mix. A few of the teeth were a bit unusual. In the 4th photo I have a few questions. On the top row, second tooth from the right, is that a rodent tooth? Then (4th picture) second tooth from the right, that one has a strange “hook to it”. Also, second row, third from the right. Anyone know what those are? Thanks in advance!
  13. I spent the morning screening in the Post Oak Creek of Sherman, Texas today. I found lots of small shark teeth...all different types. Tooth enamel from Mastodon/Mammoth and bits and pieces.
  14. A Ptychodus first for me

    Found this partial tooth today. Thinking it is Ptychodus decurrens. A first for me.
  15. Got out for a brief 30 minute hunt in September at my favorite Basal Atco outcrop in Travis County for Ptychodus. I found a couple of rare teeth - P. latissimus! Please see pics. The largest is 26 mm tooth width (TW)) with 13 mm tooth height and 6 mm crown height. The smaller fragmented tooth is >16 mm TW. Also, at another location in August, I found a couple of nice teeth: a 23 mm TW P. mammilaris and a 16 mm TW P. mortoni. Both had complete roots for a change. Probably 90% of Atco locations around here have no or very few macro fossils except oyster/clam fragments. But, this one has yielded about 45 Ptychodus teeth over two years plus many regular shark's teeth. Most of these teeth are absent most or all of the root mass. Ptychodus finds have included: 1 P. atcoensis (15 mm TW), 1 P. mammilaris (9 mm TW), and the balance are P. mortoni up to 26 mm TW or unidentified species <8 mm TW. I am especially pumped up with these two finds!
  16. Possible partial Ptychodus ???

    Found this this morning while going through some of the POC gravel I brought home last weekend. Whatever it is, it's a first for me from the POC. Looking online and in the forum, it sort of has the look of Ptychodus mortoni. Am I close or way off base? If I'm way off base, give me a break. I turned my thinker off once the work week ended. Thanks in advance David
  17. Ptychodus tooth?

    According to geologic map this location belongs to Austin Chalk. This is a construction site, the rock color change from tan to gray. I found this specimen in the gray shale like matrix. Is it a baby Ptychodus tooth? I have never seen a flat top before
  18. Ptychodus ID help

    Hi all I found these two ptychodont teeth from Post Oak Creek in Sherman, TX. I've looked at Welton and Farish's book and through the ptychodus ID page on the Fossil Forum. My best guess is that the first set of three photos are of Ptychodus atcoensis (there is a slight chevron pattern to the ridges, though one end is disrupted by a crack). The second set of two photos is of Ptychodus latissimus (best guess) since there is some granulation at the margin, the crown is low (root is missing in specimen), and the few ridges are relatively sharp (worn tooth). I wanted to see what other members thought. Thanks!
  19. Got a new case for some of my Ptychodus whipplei teeth I have found over the past couple of years. Still need one more. Was inspired by a trip with the Dallas Paleo group last week and thought they deserved better than a jar.
  20. Ptychodus Rugosus? N tx

    Found this large Ptychodus in a creek running through Eagle Ford Group(86-92 mya). Could it be Rugosus? Max size is 46 mm, this one is 40.6 mm/1.6 in. Thanks!
