Description

PLATYCERAS is a marine gastropod or snail. These snails are extinct though they resemble modern snails. They are often found in many marine deposits around the world. This snail is often found attached to crinoids and the anal tube. It feeds off the discarded waste of the crinoid thereby being a symbiotic creature with the crinoid.

The Rochester Shale is a wonderful exposure of Silurian rocks of Caleb’s quarry in Middleport New York.

The gastropod sits majestically on a gray matrix 1 1/4 inches by 1 1/4 inches. The gastropod is beautifully formed and is 5/8 by 1/2 inches.

Professionally prepared with micro air abrasive technology.
