Figure 6 in Revised systematics of Palaeozoic 'horseshoe crabs' and the myth of monophyletic Xiphosura
Figure 6. Schematic of the xiphosuran ground pattern. Somites are labelled 0–XVII; 'tl' indicates the telson, 'gills' the position of gills on the five posterior opisthosomal appendages, 'm' the mouth, 'a' the anus, and 'g' the gonopores. The appendages are shaded with the light ramus representing the endopod, the light grey the basipod, and the dark grey the exopod. The appendage of somite VII is reduced in the majority of taxa into the chilaria. It is possible that appendage VII may also have possessed a reduced exopod as in appendage VI given its intermediate position between appendage VI and the biramous opisthosomal appendages, but there is currently no evidence for this. To the left the somite compositions of the fused xiphosurid cephalothorax, thoracetron, and pretelson are shown, along with the varying combinations of segments that can form the diplotergite in bunodids and pseudoniscids.
