The Pohlsepia mazonensis fossil was found specifically in the Pit 11 region, within the Francis Creek Shale Member [7]. Like most soft tissue fossils found in Mazon Creek, it is preserved as a 2D light-on-dark discolouration of the matrix [8]. The Francis Creek Shale Member of the Carbon Formation has a diverse array of preserved plants and ...
