Icthyocrinus laevis Crinoid Calyx 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 crinoid calyx fossils from Middleport, New York USA. This fossil is known as Icthyocrinus laevis (Conrad, 1842). It was found in the Rochester Shale and existed in the Silurian Period.

Another beautiful specimen fossil of this species can be found at this web site http://www.primitiveworlds.com/crinoids-14.html
