In October of 2021 I made a 4 day trip to the Marble Mountains of Southern California to look for trilobites. The order of note is Redlichiida. The biggest percentage is Olenellus followed by Bristolia then Mesonacis. The vast majority of finds are just cephalons followed by thorax pieces. Last year I hunted here about 8 days. I probably found over 400 cephalons (could be a way higher) but only 2 completes with 3 maybe's as there are buried. With all that I've only found 1 pygidium on its own. There are a few other fossils to be found at the site. A couple brachiopods, a hyolith, and a few oth
Hi. My name is Adam and I'am new to the forum. I am trying to identify correctly all my fossils and more i read than more questions I have. first position in my catalogue of fossils is this trilobite cephalon from Latham Shale, Providence Mountains in California. Previously was identified as a Fremontia fremonti but I am not sure about that. It's 26 mm wide. I don't know if the details of the specimen are good enough to say what species is it. I would be very pleased with some help.
