Trilobites - Southern California - Marble Mountain near Ludlow
ezeemonee posted a topic in Member Collections
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.- 2 replies

Hello, Fellow Fossil Enthusiasts! I'm hoping that someone here might be able to help me in identifying these fossils, because I have hundreds of them in various stages of development, and in all of my research I have yet to find anything that remotely resembles what I've got! That is, until I found this forum - I've seen a few fossils identified here that were the very first that closely resembled what I've found, so my hope has been renewed that someone out there can help me out. I look forward to what new information might come my way! Scott

Hello everyone, I am hopeful that I can get some information about this rock/fossil. I see quite a few different shapes in this guy here, but I need to make sure that my imagination is not running away with me. I don’t know if I should keep trying to brush clean, to show what I believe is the fossil. or continue. My Indian artifacts consume a lot of spare time, and space enough as it is. but now this guy got me really intrigued. thanks in advanced everyone.

Okay, I finally unpacked some boxes a couple of weeks with the intent of finally getting this officially named. I believe it is Palmoxylon Mohavensis and I believe from the Miocene. Found in the Mojave Desert in California, north and east of Red Rock Canyon and north and west of Last Chance Canyon about 40 years ago. Size of overall specimen is approximately 4" x 5" x 6" In addition to not knowing the true identity, I think this is also down by the roots? Starting with the end that has been cut and somewhat polished. Graining is confused leading me to think root end of tree?? Opposite end

Found this partially submerged in the soil. Initially thought it was some kind of egg, but when I dug it out and felt how heavy it was I knew it was not. It is almost perfectly spherical, very smooth, and dense. There is a tiny nodule on one end (not visible in this photo). After doing some research, I suspect it is some kind of bladder stone, possibly struvite or oxalate. Bladder stones are common in canids and felines but other animals can get them too. (Click here for an examples). Just curious if anyone else has found similar stones, and if there is any way to judge age? Would be super cool if it came from, say, a dire wolf!
