Localities of the Miocene:

The Monterey Formation of California

The Monterey Formation is a vast area of marine deposits rich in fossils. It covers both a large area of California and an extended period of time. Particularly exciting are the fossil whales and dolphins, as well as the large numbers of finely preserved crabs. The singlemost important find, however, is the collection of kelps and other large soft-bodied seaweeds, which are seldom found as fossils elsewhere.
