Shell Specimen: Sea Stars and Brittle Stars
“Shelling” is a fun for professional scientist and amateurs alike. A majority of the shells below are composed of the mineral aragonite CaCO3. Many of my modern or “recent” shells have fossil relatives in my Fossil Gallery. Below I have organized images and data of some of my sea shells.
Special thanks to Tina Petway, Lucy Clampet and Gary Kidder for giving me what I could not find.
