Answers to some of our most frequently asked questions about the Department of Invertebrate Zoology and Geology. 

How may I request a loan?

Please submit your request to the appropriate Collection Manager (Recent Invertebrates: Piotrowski; Fossils, Minerals and Diatoms: DeMouthe) or Curator (Mollusca: Gosliner; Echinodermata: Mooi; Cnidaria: Williams; Fossils: Roopnarine).

Where can I go to collect minerals/fossils?

In the Bay Area, most potential collecting sites are on private land or in a county/state/federal park, where collecting is not allowed. We suggest joining a local gem and mineral society (there are lots of them in Northern California and elsewhere) or taking a class at the nearest university or community college. Those groups often take field trips to local sites of geologic interest where collecting is allowed—and learning some geology along the way makes it more fun!

Where can I go to see minerals and fossils on exhibit?

The Academy's Gem and Mineral Vault can be experienced by taking a Behind-the-Scenes Tour. The California State mineral collection, which used to be on display in the Ferry Building in San Francisco, is now located in Mariposa, near Yosemite, where it is displayed at the County Fairgrounds, in the care of California State Parks. (Note that it is unknown at this time whether that park will survive the State's government shutdown schedule; we recommend calling ahead.) Additionally, there are a few minerals on display at UC Berkeley and Stanford, though no organized exhibits. The largest nearby mineral and fossil displays are located at the Los Angeles County Museum of Natural History.

I think I've found a meteorite/dinosaur bone/fossil. How can I tell if it's real? Can I bring it in and have someone look at it?

We recommend taking a couple of clear photographs of your specimen and sending them to us either by email or as prints in the regular mail. In some cases, you can make an appointment to talk to someone on staff about your specimen.

Are the collection data for Recent Invertebrates available online?

Yes, please follow this link. Only a portion of our specimen lots are digitally cataloged oso this data reflects a partial set of our holdings. Dry shells, for instance, are mostly not digitized at present, so please feel free to inquire if the group you seek is not represented in the online records.

Who can borrow specimens from the IZG collections?

Any qualified research scientist with an institutional affiliation, including graduate students via their faculty advisors, is eligible to borrow specimens for approved scientific projects. Final approval of any loan is at the discretion of the Collection Managers and Curators. However, most eligible loan requests are approved.

Are the CAS IZG collections open to non-staff for study?

Yes, the collections are available for study by qualified researchers by appointment. Please contact the Collection Managers or Curators for details.

Where are the mineral/gem/fossil exhibits in the Academy?

Visit portions of the Gems and Minerals Collection on the public floor in the "Gems and Minerals Unearthed" exhibit, which opened in 2016.

The Academy's new building "breathes," and the temperature and humidity inside the display areas usually reflect the conditions outside. Because most natural history specimens cannot be displayed under these circumstances, special climate-controlled cases were built for the main floor exhibits.
