Caryocrinites ornatus Cystoid Fossils


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 cystoid fossils from Middleport, New York USA. This fossil is known as Caryocrinites ornatus (Say, 1825). 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

The next picture shows the same cystoids buy you can see their almost full length stems down to the holdfast. Also a Striispirifer niagarensis (Conrad, 1843) brachiopod fossil on that matrix as well.
