Diagnosis
ReferenceDiagnosis
P. Brodkorb 1958Resembles living Phalacrocorax auritus (Lesson) and Phalacrocorax wet- morei Brodkorb, 1955, from the Bone Valley Pliocene of Florida, but slightly smaller; cuneiform fossa deep but much shorter, extending proximad only to level of external igamental attachment; distal fornix shorter. Length, 67.5 mm.; width of metacarpal II, 4.5; width through trochleae, 5.6; width of distal end, 5.7; distal fornix, 6.0. Wetmore (1933) reported the heads of two coracoids slightly smaller and more slender
than in P. auritus. They are thought to represent the species here described.
