Sjfriend Posted January 18, 2021 Share Posted January 18, 2021 I am looking at some rocks already collected from and am going back to the Latham shale location in the southern California desert and wondering if anyone knows of a photograph or good drawing of the hypostome from Olenellus / Mesonacis / Bristolia trilobites? Would hate to toss a rock only to figure out later what was on it Have looked a bit but im traveling so only have my phone and going through a bunch of PDFs is a pain! Thanks for any ideas! @Kane @piranha? Link to comment Share on other sites More sharing options...
