facehugger Posted September 10, 2019 Share Posted September 10, 2019 Future for inquiries, always good if you can include the location or formation where the specimen was found. An object for scale in the photo is always helpful as well. Cool find! Link to comment Share on other sites More sharing options...
DPS Ammonite Posted September 10, 2019 Share Posted September 10, 2019 It is a calcite septarian nodule. The Eagle Ford Group is a prolific producer. They are often fluorescent under both long and shortwave UV light. My goal is to leave no stone or fossil unturned.
