Hello again! This post will be about some beautifully preserved Triarthrus fossils (and my first complete Trilobite finds). Some of them even have the eyes preserved! I found these at a local train station, and the site of significant construction lately. I believe most of the to be E. eotoni, and the last one to be E. rougensis or spinosus. It may not be visible in the picture, but the last one has a streak of pyrite along the side of its cephalon / upper thorax. Could this be some kind of soft body tissue preservation, similar to those of the Beecher's Trilobite bed?
