Here is a Super detailed  graptolite from a classic site in NY.

Graptolites from this site are preserved in Spectacular detail. These creatures thrived in the warm inland sea that covered the area during the Silurian Period some 420 million years ago. The fossils living near what is now Middleport, New York were established near a delta system that periodically buried the colonies in silt. This silt eventually hardened into stone that preserved the crinoids in glorious detail.

The Rochester Shale Formation is famous for the fossils found there. Because of the fine grained shale the preservation is great. It was formed during the Silurian Period when that part of New York State was a shallow salt water tropical sea and teeming with life. Because it was near the equator and prone to storms fossil formation was easy. The storms would stir up the ocean floor but also the storms moved on to land. It picked up sand and mud which then washed into the shallow seas and lagoons covering the animal. The animals would die and begin to turn into fossils. This Large size Graptolite was one of the victims of just such a storm.

This Large size Graptolite has exceptional detail . It is 3 inches by 2 1/4 inches wide. It sits on a piece of roughly triangular gray matrix rock that is 5 1/2 x 4 1/2 It has been meticulously prepared using air abrasive technology.
