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).

Aulopora conferta Coral Fossil

 

This fossil is really nice with Aulopora conferta? (Winchell) coral growing on what might be Hexagonaria.(Gürich, 1896). It was found in the Bell Shale of the Traverse Group at Carmeuse Quarry, Rogers City, Michigan, USA. The fossil dates to the middle Devonian Period (Givetian Stage).
