Indian bead
{{Short description|Fossilized stem segment of a crinoid}}
Indian bead is a colloquial American term for a fossilized stem segment of a columnal crinoid, a marine echinoderm of the class Crinoidea. The fossils, generally a centimeter or less in diameter, tend to be cylindrical with a small hole (either open or filled) along the axis and can resemble unstrung beads. The fossils are abundant in certain areas, including parts of the American Midwest where they are present in gravel. They are sometimes also referred to as "Indian money".{{cite book|last1=Weeden|first1=William Babcock|title=Indian Money as a Factor in New England Civilization|date=1884|publisher=N.

The same item is known as Bonifatius pfennige in German ("Saint Boniface pennies") and St Cuthbert's beads in the United Kingdom.
