Summary

The thick Lower Cambrian Waucoban Series of eastern California and western Nevada contains a relatively diverse fauna, and provides an opportunity to analyze patterns of first and subsequent occurrences of Early Cambrian Metazoa. Three zones are recognized (Fallotaspis, Nevadella, and Bonnia-Olenellus), along with a lowennost pre-trilobite intelVal that has not been assigned to a fonnal zone. These zones are useful for correlation within North America, but intercontinental correlations are uncertain. All of western North America occupied a single, uniquely homogeneous faunal province during Early Cambrian time, probably as a result of the tropical positioning of the entire region. Faunal relationships with other regions of the world are less clear. The paleoecology of the Waucoban Series is dominated by Grand Cycles, and adaptive innovations appear to have taken place primarily in shallow subtidal settings.
