Tyrannosaurus premaxillary tooth

About the Fossil Museum


The Online Fossil Museum collection has been developed to fulfill the mission and purposes of the Departments of Geology and Biology and the Hanson Research Station in harmony with the University's mission of education, research and service.


The SWAU collections are the property of Southwestern Adventist University, the EHRC collection is the property of the Earth History Research Center, and the HRS collection is the property of the Hanson Research Station.


Approximately ninety percent of the entire paleontological collection are fossil vertebrates. The most significant part of the vertebrate collection is the HRS vertebrate collection from the Upper Cretaceous Lance Formation of Wyoming.

The Collection houses type specimens and makes them accessible to the scientific community as prescribed by the International Code of Zoological Nomenclature (Recommendation 72F). The University is committed to maintaining the Repository as a permanent educational and research facility.


Specimens are collected, prepared, and curated in accordance with the Society of Vertebrate Paleontology Statement of Ethics.
