Fossils are traces of life such as that allow geologists to record and describe the diversity of life forms that have existed on earth throughout its history. There are three domains of life: bacteria, archaea, and eukaryota. The animal kingdom, which is part of the domain eukaryote, is subdivided into several phyla. The Limper Geology Museum displays interesting fossils from several of these phyla, including Arthropoda, Brachiopoda, Bryozoa, Chordata, Cnidaria, Echinodermata, and Mollusca.
