The oldest hyolithids (Cambrian Series 2, Montezuman Stage) from the Iapetan margin of Laurentia
Abstract The recent description of the nevadioid trilobite Buenellus chilhoweensis Webster and Hageman, 2018 established the presence of early Cambrian Montezuman Stage (Cambrian Series 2, Stage 3) faunas in the Murray Shale of Chilhowee Mountain, Tennessee. The description recognized the oldest kno...
