Tour of Steve Jorgensen’s Ammonite Collection

Steve Jorgensen has accumulated a world-class collection of ammonites from the Western Interior Seaway and has invited WIPS members to his home to tour his collection. During the tour, Steve will show examples of the wide variety of ammonites that lived during the Campanian and Maastrichtian Stages of the Late Cretaceous. You will see closely coiled planispiral ammonites, as well as weirdly shaped heteromorph ammonites and straight baculites. As part of the tour, he will touch on how ammonites fit in the ecosystem of the Western Interior Seaway.

Several ammonites in his collection show signs of predation from other creatures that feasted on ammonites in the Western Interior Seaway.

The tour will last 2 hours, beginning at 1 pm, and is open to adult and high school WIPS members. It is limited to 10 participants. Cameras are welcome. Participants are encouraged to bring Western Interior Seaway ammonites with locality information that you would like Steve to tentatively identify.

And plan to bring food to share with the group.
