Materials include fossil invertebrates and plants, microfossils, rocks, minerals, meteorites and tektites. Although an exact count has never been made, the collection is estimated to contain about 4 million specimens.
The Non-vertebrate Paleontology Lab does not identify or conduct analyses on possible meteorites or tektites. If you believe that you are in possession of either a meteorite or tektite, we suggest that you contact others near where you are located, such as a local gem and mineral club.
