Starfish fossils are the preserved remains of echinoderms, often showing distinct five-armed symmetry preserved in sedimentary matrix. They are highly prized by collectors for their detailed skeletal plates, typically found in marine-deposited shales and limestones. Look for specimens in areas formerly covered by ancient oceans, where rapid burial preserved the delicate structure before decomposition.

Field-hunting tip
Look in sedimentary limestone or shale country, the host setting where starfish fossil typically forms. If you start seeing calcite, pyrite in float, you are in the right ground. Field specimens usually show a pentameral radial symmetry habit, so train your eye for that shape before scanning the outcrop.
