Genus Paraphysornis Alvarenga, 1993
Type Species – Physornis brasiliensis Alvarenga, 1982 . Included Species – Only the type species.
Distribution – Upper Oligocene or the Lower Miocene of Southeast Brazil.
Diagnosis – Maybe the smallest of the Brontornithinae , the size being comparable to that of a smaller-sized Brontornis burmeisteri ( Figs. 1B View FIGURE 1 and 2B View FIGURE 2 ). The mandibular symphysis is longer and narrower than in the remaining Brontornithinae (e. g. Alvarenga, 1993: Fig. 1 View FIGURE 1 ), being, however, proportionally wider and shorter than in the Phorusrhacinae . The cotyles of the tarsometatarsus are slightly quadrangular, especially the inner one (e. g. Alvarenga, 1993: Fig. 2 View FIGURE 2 ).The lateral edge of the hypotarsus expands until very near to the lateral part of the lateral cotyle, not forming the lateral crest characteristic of Physornis .
