Answer 3:
You are in luck in California, as there are may
fossil beds in the local area. Common fossils
found are sea shells and petrified wood fragments
such as cane. I have found fossil shells in the
San Rafael's and in wash basins of streams. The
easiest to find fossils are found in limestone or
sandstone sediment which can be identified by the
layered deposits. (The layers may not be
horizontal anymore!)
Check our local book stores for fossil finding
maps -- these may direct you to areas witch have
been well picked over, but you should look after a
rainstorm has brought new rocks to the surface.
There are a number of good field guides --
petersons, golden books and others. These are
useful to prevent you from over looking a
fossil... I found my first fossil in Colorado on a
bike trip (about a mile from my house) --
California is a great place for certain kinds of
fossils. If you want to be scientific, always map
and mark each find in your collection and
correlate them to geological maps (which often
date formations to geologic eras)...
