Mesembriornis incertus (Rovereto, 1914)

comb. n.

Prophororhacos incertus Rovereto, 1914 ; Brodkorb, 1967.

Type – A dorsal vertebra; a fragment of the omal portion of the left coracoid; each the right, humerus, ulna and part of the radius; distal part of the right tarsometatarsus and phalanges 1 of digits III and IV and phalanx 3 of digit II (MACN-6934) .

Hypodigm – Type; the fragment of a cervical vertebra (MACN-6931); a tibiotarsus associated to the fibula, tarsometatarsus ( Fig. 33F and 33G View FIGURE 33 ) and complete dig- its I and II, all from the right side ( FM-P14422 ); a left tarsometatarsus, with the proximal portion missing, and phalanges 1 and 2 of digit II (MACN-6737) .

Horizon and Locality – The Upper Miocene to the Lower Pliocene, of Argentina (Huayquerian): Catamarca Province (Andalgala, Corral Quemado).

Diagnosis – Much smaller than M. milneedwardsi .

Measurements – Table 9.

Illustrations – Rovereto (1914).

Remarks – As commented by Patterson & Kraglievivh (1960:20), the “second specimen of Procariama ” described by Rovereto (1914) is part of the same specimen that this author described as Phororhacos incertus , thus being added to the originally described type material (distal tarsometatarsus associated to the phalanges). The possibility of confusing material between these two species of similar sizes and the same geological age serves as a warning.
