All these units are faulted into several terraces or mesas. Anderson (1950) states that after the Miocene volcanic accumulation, the rocks were tilted eastward, and by the middle Pliocene the area subsided and marine calcareous rocks accumulated. These beds were tilted slightly to the east, and during the early Pleistocene a transgression of the sea left a thin veneer of fossiliferous gravels on the limestone and the volcanic rocks. Later on, this surface was broken into fault blocks, the faults striking to the north, and in the central part of the island there was considerable elevation of the fault blocks.

Langston and W. Miller (pers. , May 2000), this species was a crocodile from the eastern portion of Central America that did not tolerated salt water and could have lived in the west and became extinct in this region. Other evidence that southernmost Baja has not been separated for a long time is the similarity of the Pliocene faunas from that area and from central Mexico. Mammalian species can change in as little as 300,000 years, although many can live much longer without appreciable change. However, many of the Pliocene species could have moved into Baja California through Arizona or California.

1983) noted, several major geologic events are ultimately related to the origins of islands, and these include subsidence, uplift, erosion, and volcanism. 1; fig. 2). The numerous islands and islets in the gulf can be separated into three different regions with general characteristics, which unite them: northern, central midriff, and southern gulfs areas. Northern Gulf Area or North Midriff Islands In the northern part of the Gulf of California, much of the tectonic relief has been obliterated by deposition of sediments delivered by the Colorado River, which has been building its delta for about 5 Ma.
