old bones Posted September 23, 2023 Share Posted September 23, 2023 (edited) These are my finds from a nice sample of sandy micro matrix from the Post Oak Creek in Sherman, TX. As others have attested, there are many fossils of sawfish to be found at the micro level. I very much enjoyed picking these as I find them as aesthetically pleasing as the denticles that I love to collect. The scale throughout is one millimeter. The stream wear made the ID of the oral teeth a bit difficult at times, so I lumped Ptychotrygon and Texatrygon sp. together. It was a real treat to find these Sawfish Rostral spines which I believe are those of Ischyrhiza texana. I found lots of interesting denticles. The Cantioscyllium decipiens and Chiloscyllium greeni teeth were distinctive enough for me to ID, but the ‘regular’ shark teeth were a bit too worn for me to be sure. Any help there is much appreciated. I think I found at least one Hybodus sp. tooth. (Cretalamna appendiculata ?) The fish material included the ubiquitous Enchodus sp. teeth and palatine bones, many fish coprolites, and lots of otherwise unidentified teeth. I photographed a few the more interesting bones some of which are probably of Pleistocene origin. continued...

old bones Posted September 23, 2023 Author Share Posted September 23, 2023 continued. Here are a few microscopic Crustacean fragments. Some Foraminifera (including Lenticulina sp. ?) A few of the better preserved Rhinobatos sp.. And some tiny fragments that may be tooth plates or perhaps tuberculate skull fragments. Any corrections or additional info is appreciated. Thanks for looking. 2 15 Link to comment Share on other sites More sharing options...

Al Dente Posted September 23, 2023 Share Posted September 23, 2023 Very nice. I think the ones you labeled “denticles” with “ Pycnodont teeth?” are actually Paralbula casei. Here’s a Google image screenshot of Paralbula casei. 3 1 Link to comment Share on other sites More sharing options...

Mikrogeophagus Posted September 24, 2023 Share Posted September 24, 2023 Great finds and photos! POC micros are so often overlooked. Your last photo of textured fragments may be pieces of plethodid fish parasphenoid bone which would've attached countless tiny conical teeth. 1 Link to comment Share on other sites More sharing options...

ClearLake Posted November 18, 2023 Share Posted November 18, 2023 Just seeing this now for some reason. But I have to add to the chorus of compliments on the photography and composition. Very well done. Oh, and of course the fossils are very nice also. 1 1 Link to comment Share on other sites More sharing options...
