Twinlukers Posted March 13, 2016 Share Posted March 13, 2016 Hello everyone!! We found this piece over the weekend in the Glen Rose Formation area. We have no idea if it is a bone with attached ribs or some shellfish. Please help us out.. Link to comment Share on other sites More sharing options...

JohnJ Posted March 14, 2016 Share Posted March 14, 2016 This is likely a Goodland or Walnut Formation find. I think you have the exterior mold of an ammonite (possibly Oxytropidoceras sp.). It looks like the oysters that grew on the ammonite's surface now make up part of the mold. The human mind has the ability to believe anything is true. - JJ Link to comment Share on other sites More sharing options...
BobWill Posted March 14, 2016 Share Posted March 14, 2016 Good call JohnJ. The ammonite features that look like ribs are indeed called ribs and the area where they attach is the very broad ventral keel indicative of Oxytropidoceras sp. With their thin profile and sharp keel they must have been very fast swimmers. The close spacing of the ribs is also a feature of oxys. Link to comment Share on other sites More sharing options...
Twinlukers Posted March 14, 2016 Author Share Posted March 14, 2016 Thank you John!! Wow you hit it right on!! We are learning so much. I thought to myself it was an ammonite because the area was full of them. Plus with out cleaning it I knew that most Ribs do not have a Web feature attaching to the main spin. I'm just grateful for the opinions and knowledge you guys give me as I do my research. Rosie said thanks she was the one questioning what it was. Note: we were in the Glen Rose area.

Twinlukers Posted March 14, 2016 Author Share Posted March 14, 2016 Ok everyone don't think I'm crazy please but Look at this picture!!! I know it's a rock but what do you see? Very interesting eye sockets and the shade of this formation. It's quartized in the sockets and around the makeshift jaw line. What a find. Ha ha!! It's a combination of Calcite Quartz and limestone.
