Eopeachella is an extinct genus of trilobites, fossil marine arthropods, with species of probably small size (largest headshield (or cephalon) 1.1 centimetres or 0.43 inches long), entire, articulate specimens have not yet been found. It lived during the Toyonian stage (Upper Olenellus-zone), in what is today the South-Western United States.[1]Eopeachella angustispina is the only known species in this genus (i.e. the genus is monotypic).
