I live in San Diego, and I've kept cephs, and been on Tonmo, for years. My five year old really wants dad to take him out to find some fossils (ceph or otherwise). I think he expects to find a complete T-Rex skelleton, but I'm sure he'd be tickled to find anything. We can range as far notrh as Santa Barbara, and as far east as Phoenix AZ. I know there are fossilized coral reefs near El Centro (Imperial county - East of me) with some shells, but it would be great to find an ammonite, or fish skelleton. Any tips would be greatly appreciated. (A little "How" in addition to the "where" would also be great) Thanks!
