SUMMARY:Tour of Steve Jorgensen's Ammonite Collection
DESCRIPTION: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. \nSeveral ammonites in his collection show signs of predation from other creatures that feasted on ammonites in the Western Interior Seaway. \nThe 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. \nAnd plan to bring food to share with the group.

SUMMARY:November 2025 - Member Show ‘n Tell & Annual Business Meeting\, Short talks about field trips & activities
DESCRIPTION:Steve Miller -Two Decades with the Cretaceous Rocks and Fossils of the Comanche National Grassland\nWIPS has been offering trips to the Comanche National Grassland for 20 years. This area of Colorado presents modern landforms of prairie and canyon overlying rocks formed on the floor of the Western Interior Seaway. Over the years\, WIPS members collected dozens of marine specimens. Some vertebrate specimens have been donated to various museums.\n\nThis video was created for an audience with a fundamental understanding of the Western Interior Seaway. Hopefully\, everyone will see how WIPS has contributed to supporting the science of paleontology through the kinds of information that were reported to the US Forest Service. WIPS members have collected some amazing fossils over the past twenty years.\n\nDennis Gertenbach – Douglas Pass Insects: What They Tell Us About Ancient Colorado\nThis presentation will show fossil insects I have found at Douglas Pass from the Eocene Green River Formation\, dating to about 50 million years ago. Douglas Pass is well known for the large variety of fossil leaves found there. These leaf fossils\, combined with studies of the Green River Formation geology\, give a good picture of what the area looked like during the Eocene. However\, the fossil insects also found at Douglas Pass bring the Eocene ecosystem to life. By comparing these insect fossils to modern insect relatives\, a picture of life in ancient Colorado comes to life.
