Description
Here is your chance to own a classic fossil from a classic site.
It is harder and harder to obtain fossils from this private quarry in Middleport, New York
This is an exceptionally rare and very often overlooked Silurian Brachiopod Fossil from the Rochester Shale of New York.
This Silurian Leptaena Brachiopod was collected decades ago and just recently prepared by our prep lab..
Here is a Super detailed and rare crinoid from a classic site in NY. Brachiopods are also known as lamp shells but are not related to clams. The Silurian Leptaena Brachiopod is an extinct marine sea shell. They are found in Silurian through Middle and Upper Paleozoic marine outcrops around the world. The outside is characterized by a half round shape.
Brachiopods from this site are preserved in Spectacular detail. Because of the wide variety and number of these fossils were preserved in silt the detail is amazing. Because of large storms such as hurricanes the seas were often rough but the storms did not stay over water. They often hit land and washed silt and sediment into the sea and because this silt was so fine it preserved these fossils in great detail.
This Silurian Leptaena Brachiopod Fossil was actually an animal. But they are animals living inside inside a protective shell. They lived during the Paleozoic.
This Silurian Brachiopod Fossil lived in the warm inland sea that covered the area during the Silurian Period some 420 million years ago. The Brachiopodss living near what is now Middleport New York were established near a delta system that periodically buried them in silt. It is because the silt hardened into stone that preserved the fossils in detail.
This Leptaena has exceptional detail and it has been prepared using air abrasive tools.
LEPTAENA brachiopods were quite common in the Paleozoic seas but they can be found in Ordovician, Silurian and Devonian deposits. Brachiopod Leptaena usually have concentric wrinkling and concentric lines on the shell. they average around 1 inch and are somewhat semi-circular.
The Leptaena is 3/4 inches long. It sits on a roughly triangular gray matrix 1 1/4 by 1 1/8. It comes in a plastic case.
