Reference | Diagnosis | |
---|---|---|
N. Valdes et al. 2017 | Apalone amorense shares with other species of Apalone high variability in the location of the posteriormost neural reversal and the location of the reversal, which often occurs at N5 Apalone amorense is distinguished from other Apalone by costal contact at the midline posterior to N6, permanent loss of C8, and potentially greater interorbital width. |
