Oldest fossils I have ever found as these Early Cambrian Trilobites are estimated to be half a billion years old!  Still trying to wrap my head around that.  lol

Much thanks to the SoCal Paleo Society which organized this field trip back in 2021 out to the remote site in the Mojave Desert.  


Based on various ID help I got, these are mostly Bristolia bristolensis, Bristolia mojavensis, and some others are not ID'ed yet.  These were small and around an inch or so in width but one member of our party found part of a much larger one further up the mountain.  The ID sheets with examples were brought by the trip organizers to help with ID's.


The Latham shale these Trilobites are found in is somewhat brittle and I used a putty knife to carefully pry apart layers to look for Trilobites without shattering them.  Most survived the process.  These are just trace fossils but have some pretty good detail surprisingly.
