NATICONEMA 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.
The Rochester Shale is a wonderful exposure of Silurian rocks of Caleb’s quarry in Middleport New York.
This gastropod sits on a piece of matrix 2 1/8 by 2 1/8. There is a crinoid stem and several bryozoans on the matrix as well. The gastropod is beautifully formed and is .56 inches long and .36 inches wide.
