Proaster Brittle Star Fossil

 

My September 2021 trip to Alpena, Michigan USA included a visit to local paleontologist Paleo Joe (aka  Joseph Kchodl). 

This picture is of one of his brittle star fossils from Middleport, New York USA. This fossil is known as Protaster sp. (Forbes, 1849). It was found in the Rochester Shale and existed in the Silurian Period.

Genus was named by Edward Forbes (1815-1854) in Figures and descriptions illustrative of British Organic Remains. Memoirs of the Geological Survey of the United Kingdom (1849).
