Paupospira bowdeni gastropod from the Marble Hill Bed

I made a post a while back about some fossils that friends of mine had sent me from a curious locality called the "Marble Hill Bed". This post is part of a series meant to focus on the individual specimens that come from that location. Today we are looking at Paupospira bowdeni, a high turrented conispiral gastropod. This is the most common fossil found in the "Marble Hill Bed" with hundreds of individuals to be found in matrix or eroded free. The often preserve the majority of their 3D shape but generally show some compression in one axis. The opening and living chamber are tube shaped.

Specimen #2

Here are some as they lie exposed on the ground, weathered free from the rock.

The "Marble Hill Bed" is part of the Rowland Member of the Drakes formation (equivalent the Whitewater formation in Ohio and Indiana). It is upper Ordovician in age, Katian (Richmondian) stage (450-445 mya) and located near Carrollton, KY. I collected these fossils in July of 2016.
