GerberHopkinsTrilobiteData

The following table provides the morphological data for the 203 specimens used in the study. The first column corresponds to the designation name of specimens in the Institute for Cambrian Studies at the University of Chicago (ICS) or at the University of California Riverside (UCR), where the material is housed. The second column corresponds to the affiliation of specimens to the two species considered, Zacanthopsis levis (1) and Zacanthopsis palmeri (2). The remaining columns correspond to the raw coordinates of the set of 25 2D-landmarks used to capture the shape of the trilobite cranidia. Questions regarding collection localities or identification and preparation of material should be directed to the second author (Melanie Hopkins).
