Coiled Cephalopod Fossil

Finding coiled cephalopod fossils in the area around Louisville is quite rare.  This cephalopod fossil found in Clark County, Indiana, USA. I have posted an image of it before in 2013 but looking at images on my cell phone from 2018, I decided to post some fresher images from different angles.

It was on display at the Indiana University Southeast geology department as of December 2018. It was donated to them by John T. Shelton.
