Specimen collection depth, species minimum depth, and species maximum depth (in meters) were tested independently. Total degrees of freedom (df) for each test are shown. Significant p-values below an alpha threshold of 0.05 are marked with two asterisks and bold type, those below the 0.1 alpha threshold are marked with a single asterisk and bold type. Akaike information criterion (AIC) values are reported for each model. The depth metric with the lowest AIC value for each bone appears in bold type
