FlexicalymeneDescription: This one is a bit of a dilemma to characterize. It looks most like Flexicalymene senaria, a taxon woefully in need of the revision that is reportedly underway. Some FOUR different trilobites are called F. senaria. One, from, the famous Walcott-Rust quarry, is quite pustulose, while another is less so. Yet another is relatively smooth-skinned like this one. However, this one has a more pronounced “duckbilled” rostrum evocative of a juvenile Spathaclaymene (see my other offerings). Again, discretion being the better part of valor, I’ll stick with Flexicalymene cf senaria here.
