FIGURE 2 in Continuous character variation within the Glossopleura-Anoria-Sonoraspis plexus: Dolichometopid trilobites from the Cadiz Formation (Cambrian: Miaolingian, Wuliuan), California

FIGURE 2. Relative eye position and length for dolichometopids measured in this study, showing low degree to which the studied specimens demonstrate large, posteriorly positioned eyes (toward upper right; historically features attributed to Glossopleura) or smaller, more anteriorly positioned eyes (toward lower left, normally attributed to Anoria and Sonoraspis). Data set equation shows a shallow slope and very weak correlation.
