Diagnosis
ReferenceDiagnosis
P. Brodkorb 1955Very similar to modem Phalacrocorax auritus flor- idanus (Audubon) but bones in general less robust.
Coracoid with anterior intermuscular line situated farther laterad. Humerus with head shallower, ligamental furrow relatively longer, pneumatic fossa narrower and deeper, and condyles averaging less
deep. Ulna decidedly less robust. Carpometacarpus somewhat more delicate, but with first metacarpal more produced. Femur averaging longer and narrower. Tibiotarsus with both proximal and distal ends
more slender, but with internal condyle relatively deeper. Tarsome- tatarsus averaging more slender, but shaft slightly deeper. The frag- mentary specimens of synsacrum, scapula, and radius do not show differences from P. auritus,nor do the cervical vertebrae and digits.
