Regional terrane analysis has been combined with a global evaluation of plate kinematics to produce a new tectonic model for the Mesozoic evolution of western North America and its associated marginal seas. The model employs a two-tiered data reliability ranking system to resolve conflicts within data sets. The lower tier of the ranking system involves the assignment of a numerical rank to paleomagnetic and/or paleobiogeographic data based on each data set's reliability. The upper tier of the ranking system places the paleomagnetic and paleobiogeographic data in perspective by assigning a relative order of importance to different types of data. The most reliable data are considered to be “departure” (rift) and “arrival” (collision) times that are tightly constrained by independent data sets. Evidence of subduction and/or strike-slip motion also ranks high in the master ranking system. Paleomagnetic and vertebrate paleobiogeographic data come next in the hierarchy, followed by invertebrate and floral paleobiogeographic data. Application of this approach to a case study, the “Baja British Columbia” controversy, has resulted in a coherent model for the entire region.
