Remember that last scene in Raiders of the Lost Ark where they box up the ark of the covenant and store it in a big old warehouse?

Well the N.W. Harris Learning Collection room at the Field Museum is a lot like that warehouse, except regular folks can walk out with some of the 1,500 artifacts stored there. These rentable items include a replica of a full-sized T-rex skull, bug specimens, hundreds of stuffed birds and animals, ancient instruments, and even fake bear feces.

Curious City recently stumbled across this more-than-100-year-old collection while researching a question from listener Robert K. Elder. We learned that the Field Museum’s program began as a resource for Chicago teachers to bring educational displays to their students.

But the Field Museum eventually opened its rental collection to the general public. Regular citizens can take home almost any item through rental plans that range from $10 for one item to $100 for 40.

The collection’s administrator, Wendy Quinlan, recently gave us a tour with Robert and his 9-year-old daughter, Eva, and we came up with this list of some of the more notable items.
