|---|---|---|
| P. Brodkorb 1963 | Referable to the family Phorusrhacidae,subfamily Phorus- rhacinae, on the basis of: gigantic size; distal foramen of tarsometatarsus bifurcate,withforamenforextensorbrevisdigitiIV openingthroughdistal end of shelf bounding outer intermetatarsalspace (confluent with foramen for tibialis anticus artery on plantar surface of shaft in Brontornithidae, separate but on plantar face in Rheidae); lower end of shaft not bilaterally expanded (flaring toward roots of trochleae in Rheidae); plantar surface of shaft flat above trochleae (concave in comparablegroups); trochleae nearly on a plane (strongly arched in Psilopteridae and Rheidae); poste- rior wings of trochleae obsolete (well developed in Psilopteridae) |
