Mission
The Hell Creek Paleontological Society is a organization focused on the study of fossils with the goals of inspiring and furthering the educational aspirations of our community through knowledge and scholarship. We are open to everyone, regardless of age, experience or educational background. We argue that the study of fossils, fossil hunting, and fossil collecting are great ways to motivate children of all ages to explore the complex natural world around them. Indeed dinosaurs are often the path to a lifetime pursuit of science, technology, engineering and math (STEM). The HCPS intends to support and encourage all like-minded families, students, educators and researchers to advance our knowledge of Earth history.
