Archimedes, or Corkscrew Bryozoans, is a unique little fossil that rarely exceeds 1 to 2 inches in length. These samples are Mississippian age (approximately 325 to 360 million years old) corkscrew bryozoans collected from Kentucky. Also known as moss animals, bryozoans were filter-feeding organisms that lived in colonies on the sea floor. Archimedes formed from lace-like fronds that attached to the organism in a corkscrew pattern.
An information card with details on the fossil is included. Typical samples sizes are generally 0.5 to 2.0 inches in length or width but can vary based on availability and natural fossil shape.
