The ranges of these species were extended to make them square with information based on phylogenetic topology. Extended lineages are depicted as dashed lines that represent ghost lineages sensu Edgecombe (1992). The generic or sub- familial name is placed above each of the clades within the Olenelloidea. The Clade A refers to the following nested set of taxa: Olenelloides annatus Peach, Biceratops nevadensis Pack and Gayle, Peachella iddingsi (Walcott) and P. brevispina Palmer in Palmer and Please note that these images are extracted from scanned page images that may have been digitally enhanced for readability - coloration and appearance of these illustrations may not perfectly resemble the original Peabody Museum of Natural History.
