Fossil Specimens Placed in Museums and Universities by Professional (Commercial) Paleontology

Independent professional Paleontologists have a long history of providing new and important specimens to museums and universities around the world. Beginning in the late 1700 with Mary Anning and her brother, then in the late 1800s and early 1900s with the Sternberg family, who collected in the western United States and Canada, and placed hundreds of specimens in major museums and universities such as the University of Kansas. The specimens they collected, prepared, mounted and described can still be seen on display today. The tradition of commercial paleontology supplying original fossils for study that the Sternberg family started, continues today with companies such as the Black Hills Institute of Geological Research, Triebold Paleontology, Canada Fossils, Larson Paleontology, Wards Science, Geological Enterprises and dozens of other companies.

This list is just the tip of the iceberg and a work in progress. Companies such as Canada Fossils and sister company Korite International alone have donated over 900 specimens to just the Royal Tyrrell Museum. These lists do not include the sale or donation of replica skulls and skeleton's to museums for display, Specimens listed are original fossils. Please use the following links to visit specific classifications of specimens, Birds, Dinosaurs, Fish, Sharks & Rays, Ichnofossils, Invertebrates, Mammals, Insects and Plants.

For additional information on any of the specimens listed, please contact the collections manager of the institutions posted with the specimen.
