DPS Ammonite Posted June 19, 2016 Share Posted June 19, 2016 Rib from NSR is a fish fin. Mineral is aragonite and/or calcite from part of a concretion. My goal is to leave no stone or fossil unturned. See my Arizona Paleontology Guide link The best single resource for Arizona paleontology anywhere.

DPS Ammonite Posted June 19, 2016 Share Posted June 19, 2016 (edited) Gastropod. NSR. 1 1/2 inches. Not much surface ornamentation left to help ID. Might be an Anchura substriata or Turritella trilura based on photo in "Fossil Collector's Guidebook to the North Sulphur River" by the Dallas Paleontological Society.

DPS Ammonite Posted June 19, 2016 Share Posted June 19, 2016 Ammonite from Texas or Oklahoma. It is almost 5 inches. Calycoceras tarrantense from the Woodbine Fm. My opinion...experts please confirm.

DPS Ammonite Posted June 19, 2016 Share Posted June 19, 2016 Nautilus. Texas. 5 inches. A locality and better exposed sutures would help with ID. I suggest that it might be Paracymatoceras or Cymatoceras sp. My goal is to leave no stone or fossil unturned.

CraigHyatt Posted June 21, 2016 Share Posted June 21, 2016 For this and the ammonites on your other thread, can you check for suture lines under magnification? If you can document any suture patterns, that will help with the ID. Info: Craig Hyatt, retired software/electrical engineer Experience: Beginner, fossil hunting less than a year Location: Eagle Pass, TX USA on the border with Mexico, hot dry desert Formation: Escondido, Marine, Upper Cretaceous Materials: Sandstone, Mudstone, Shale, Chert, Chalk Typical: Thalassinoides, Sphenodiscus, Exogyra, Inoceramus Reference: http://txfossils.com/Txfossils.html Link to comment Share on other sites More sharing options...
Mike from North Queensland Posted June 22, 2016 Share Posted June 22, 2016 I agree on the fish fin ID by DPS Ammonite Mike Link to comment Share on other sites More sharing options...
fifbrindacier Posted June 22, 2016 Share Posted June 22, 2016 Also, if you take photos of the whorl cross-section of the ammonites, it might help.

DPS Ammonite Posted June 28, 2016 Share Posted June 28, 2016 William, your best bet is to take the rock with the gastropods into a Dallas Paleo meeting. Seeing the rock in person might jog someone's memory. My goal is to leave no stone or fossil unturned.

BobWill Posted June 28, 2016 Share Posted June 28, 2016 (edited) Getting a positive ID for gastropods requires completely different preservation than for ammonites. While the distinctive sutures of each species of ammonite are only visible on an internal mold the ornamentation needed to identify a gastropod is not found there. Your snails without location information will just have to settle for the broader label of the class. The one from the Sulphur River might be labeled as probably one of those suggested by DPS Ammonite because they are commonly found there but it is just not possible to say for sure since it does not show us the external surface. A label should contain as much information as we can gather without unverified speculation. Edited June 28, 2016 by BobWill 2 Link to comment Share on other sites More sharing options...
FossilDAWG Posted June 28, 2016 Share Posted June 28, 2016 I bought this with no location. Why? A fossil with no location is just an interesting looking rock. Don 1 Link to comment Share on other sites More sharing options...
