In late February, 2003, the Hyde Park Mastodon was shipped to Alberta, Canada for mounting. The skeleton returned to Ithaca, NY in May 2003, and is now a major part of our Quaternary exhibit in our brand new Museum of the Earth.

Hyde Park Mastodon Shipped to the University of Michigan for Molding, Study

In August, 2002, the remains from the Hyde Park mastodon were shipped to Michigan, where they were studied by Dan Fisher at the U-M Museum of Paleontology in Ann Arbor. view their website High quality scientific molds were made of the animal before being shipped off to Alberta for mounting. See the pictures below to learn how to mold an Ice Age elephant!

below right - This is a lumbar vertebrae from the Hyde Park mastodon that is half completed. Polyurethane rubber will be applied next (the white), then a fiberglass mold (the pink).

below - Because of the complexity of the shoulder blade (scapula), it needs to be molded using three pieces. Here, Mike Cherney is preparing the second piece of this mold for the polyurethane rubber stage.
