A new fossil fauna has been discovered from a recently recognized shale unit within the middle Ordovician St. Peter Formation in northeast Iowa. It contains a variety of invertebrates and vertebrates, including soft body tissues, impressions, and 3-dimensionalpreservations. The exceptional preservation reveals a new Konservat-Lagerstatte, the Winneshiek Lagerstatte, and opens a unique window into the community that inhabited the margins of the Laurentian cratonic seaway during Middle Ordovician… CONTINUE READING
