After feasting on turkey the day before, I'm taking a run with my daughter, Emilie to do some fossil hunting in the Latham Shale/Marble Mountain area near Amboy, CA. 11/23/07 Anyone interested in coming is welcome to tag along. PM me if you have an interest. It might be a fun thing to do with your kids. The agenda is to leave SoCal Metro area early AM
(so we have a full day to play) and make the 2.5 (+/-) hour drive to Marble Mountain. Dig around looking for trilobite fossils in the shale for part of the morning, have a trail lunch, wheel around the area, maybe a little target practice for fun with .22's and then home in the evening.
The Latham Shale is a 60 feet thick formation formed by a tilted row of dark brown rocks. It is on BLM land and it's lawful to take invertebrate fossils that you may find. This area is not in the Mojave Preserve.
It's SOUTH of I-40 - however the concept of treading lightly and treating the land with respect still applies.
Remains of trilobites, mostly cephalons (heads) and thorax segments are abundant
. Slabs with complete specimens have been discovered by just splitting the shale found along the slope. The trilobite remains are mainly from the species Olenellus Clarki, animals that were more than 550 million years ago! The Latham Shale has also yielded other fossils, including some of the earliest articulate brachiopods (brachiopods with hinge teeth) known.
