Here is your chance to own a classic fossil from a classic site.
HARDER and Harder to obtain fossils from this private quarry in Middleport, New York
This is an exceptional CARYOCRINITES plate from the Rochester Shale of New York.
These Cystoids have exceptional detail . There are 2 great cystoid theca and stems attaching to bryozoan colonies. The third is obscured by bryozoans. There are two more theca on the left side that broke during recovery and were unable to be repaired but calcite crystals are visible. There are also brachiopods on the plate with one that landed on one of the stems. The stems are 4, 5 3/4, and 4 inches left to right. It has been meticulously prepared using air abrasive technology.
These cystoids were collected decades ago and just recently prepared by our prep lab..
Here is a Super detailed cystoid from a classic site in NY.
Cystoids from this site are preserved in SPECTACULAR detail. Because of the wide variety and number of these cystoids it is also assumed they lived in dense communities,
Cystoids are actually animals related to modern day starfish. They are echinoderms. They have modern relatives called crinoids living in the deep oceans today however then they lived in shallow salt water seas and lagoons. They lived during the paleozoic and were most prevalent during the Mississippian Period.
Although there were many species of cystoids, they shared a basic body styles consisting of a stem by which it anchored to the sea floor with a “holdfast”, a theca which enclosed soft body tissues, and arms and pinnules which filtered food from the water.
Cystoids thrived in the warm inland sea that covered the area during the Silurian Period some 420 million years ago. The cystoids 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.
