Table 7. Measurements of Potamotyrgon histrix. Three specimens were examined for this study: (A) MS 0415, (B) MS 0442, and (C) MS 0443. Mean (x) and Standard Deviation (SD) are expressed as proportions of disc width (% DW), and range is expressed in millimeters (mm) and proportions of disc width (% DW). Clasper measurements were taken only from adult specimens.
