Description
Table 5. Measurements of specimens of Potamotyrgon amandae analyzed in this study, including the holotype (A) MZUSP 110910. Mean (x) and Standard Deviation (SD) are expressed in 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.
