Summary[edit]

Description

Busycon snail shell geode with yellowish calcite crystal lining. Entire rock specimen is 11 cm across.

This specimen comes from the Anastasia Formation (Upper Pleistocene to lower Holocene, ~126 k.y. to ~8 k.y.) from the Indrio Pit on the northern side of the town of Fort Pierce, southeastern Florida, USA. The matrix surrounding the large snail shell is a coquinoid quartzose sandstone having abundant whole bivalve shells (see pic below). Florida’s Anastasia Formation is well known for having true coquina beds.
