Tropical and subtropical elements of the BMLC ichthyofauna are believed to be derived from one of two sources: 1) from remnant populations established as the Baja California Peninsula rifted from the Jalisco region of southwestern Mexico during the Miocene and Pliocene (~4-8 million years ago) and, 2) from the southern Gulf of California via a Tertiary paleochannel between the BMLC and Bahia La Paz (Castro-Aguirre and Torres-Orozco 1993; Sedlock 2003).
Data from paleochannel axes are relatively consistent with cross bedding data, although some channels diverge to the west (Ninke 1995).
Thickness of individual units can vary considerably over distances of tens of meters, presumably related to variation in distance from the axis of the paleochannel.
