Sjfriend Posted January 13, 2022 Share Posted January 13, 2022 OK, on my few trips to the Latham Shale in the Marble Mountains of Southern California I have found a few things that I'm just not sure of. I will include any info before each photo. Scale: little marks are 2mm, bigger numbered marks are cm 1: Ok, first I will include 2 photos of what I question as maybe trilobite hypostome. I haven't found any good illustrations of Olenellus hypostome. I've found probably 10 of these. They all look the same shape though many different sizes. 2: Next, I find a few of these each day. The cephalons from the trilobite species of this age tend to stay in one piece but this reminds me of the anterior lobe of a glabella. I have no other idea. It is round and inflated (about 4mm high) and will pop off the matrix. 3: This one I can't nail down at all. Is it a worm or what???? 4: This is a ? Looks kind of tooth-ish but I have no idea. I might try to get better photos when I find it again (still packed from my flights and driving) That is it. I've found at least a few of each of these except number 3. Thank you for your time and help. Link to comment Share on other sites More sharing options...
Kane Posted January 13, 2022 Share Posted January 13, 2022 I agree with your hunch that the first specimens in the list are hypostomes. 1 ...How to Philosophize with a Hammer Link to comment Share on other sites More sharing options...
connorp Posted January 14, 2022 Share Posted January 14, 2022 4 might be a hyolith, would need closer pictures to be sure. Link to comment Share on other sites More sharing options...

Will have to look at it when I can with that in mind. It is way different preservation then others I've found there which tend to be more of a flatter red mineral stain. Not so 3D. Shape is right though. Link to comment Share on other sites More sharing options...
MarcusFossils Posted February 1, 2022 Share Posted February 1, 2022 Specimen three is very interesting. Maybe an Anomalocaris appendage or some other kind of soft tissue creature.

Was hoping for another to say it Link to comment Share on other sites More sharing options...
