The historical core of the Academy's collection includes the Thomas Jefferson Fossil Collection, the first dinosaur fossils from North America, the only fossil collected by Lewis and Clark, as well as the extensive collections of Leidy and some of the Cope collections. Today, the vertebrate fossil collection houses more than 22,000 specimens and that number is rapidly growing through recent research efforts.

During this members-only tour, Collections Manager Ned Gilmore will showcase a few of our most impressive specimens hidden inside this remarkable collection.

Space is very limited. This members-only program is free, but registration is required. Members, please sign in to register for this program.
