Taxonomy
Pelagornis sandersi was named by Ksepka (2014). Its type specimen is ChM PV4768, a partial skeleton (cranium and right mandibular ramus, partial furcula, right scapula, right humerus lacking distal end, proximal and distal ends of the right radius, frag- ments ), and it is a 3D body fossil. Its type locality is Charleston International Airport, which is in a Chattian coastal horizon in the Chandler Bridge Formation of South Carolina.

Diagnosis
| Reference | Diagnosis | |
|---|---|---|
| D. T. Ksepka 2014 | P. sandersi exhibits diagnostic characteristics of Pela- gornis (10), including rostrum with transverse furrow, tricipital fossa situated on the ventral surface of humerus, and tibiotarsus with medial condyle markedly more anteriorly projected than lateral condyle. P. sandersi can be differentiated from other species of Pelagornis by the slender caudal portion of the man- dible [deep and squared in Pelagornis chilensis and Pelagornis (Pseudodontornis) longirostris], the more elongate beak, a larger number of mandibular pseudoteeth (31 vs. 20 in P. chilensis), and larger size. P. sandersi can further be differentiated from Pela- gornis (Osteodontornis) orri by the presence of two (vs. six) small intervening pseudoteeth between the first two large pseudoteeth in the rostral portion of the upper jaw. It can be differentiated from Pelagornis mauretanicus by the larger size of the caudalmost set of mandibular pseudoteeth, Pelagornis stirtoni by the markedly more robust femur, and Pelagornis (Paleochenoides) mioceanus by lack of a deep sulcus on the fibular trochlea of the femur.
