DPS Ammonite Posted January 28, 2020 Share Posted January 28, 2020 Sand dollars and your fossil are both echinoids, (class echinoidea), and have the distinctive five pointed structure on top. https://en.m.wikipedia.org/wiki/Sea_urchin Let us know what locality and formation this came from to help us give an ID. My goal is to leave no stone or fossil unturned. See my Arizona Paleontology Guide link The best single resource for Arizona paleontology anywhere.

Edit to give location. These came from Greene county Alabama, just noticed I didn’t give a size. They are about 1” across Link to comment Share on other sites More sharing options...
