Coquinoid quartzose sandstone matrix of geodized Busycon snail shell shown in the other Busycon photo (bottom surface of rock, 8.4 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.
