Mineral & Fossil Identification

  • Event Main Image (800 x 200)

Bring your mystery rocks, minerals, fossils, shells and artifacts to the Rutgers Geology Museum for identification. Geologists will attempt to identify your discoveries and give you insight into the origin of your specimen.

What will you discover?

Items identified at previous events include a walrus skull, Mosasaur teeth, turtle scutes, and Native American arrowheads and spear points! Identification is free, however NO appraisals will be given and gemstones will not be identified.

Identification Dates

Mineral and fossil identification is offered at our Annual Open House and at all of our Late Night at the Museum events. Check out the following links for a list of dates and times.


Can't make it to one of our ID events? Email us a few photos of your specimen. Make sure to include an item like a pen or coin for scale in your photos.

Before you bring your specimens in, here are a few tips that will help geologists with the identification:

  1. Bring as much information on your specimens as possible. If it belongs to a friend or family member, try to get the information from them prior to your visit. Information on its place of origin and how it was found are especially important.
  2. Please do not bring any hazardous materials to the museum.
  3. Extremely large or heavy objects should not be brought to the museum. Please contact the museum staff ahead of time if this applies to you.
  4. In some cases, a list of the object’s properties (weight, dimensions, magnetic properties, etc.) can help us to identify it.
