Type – Distal portion of the right tarsometatarsus ( Fig. 22A View FIGURE 22 ), associated to the ungual phalanx of digit II (MACN-6554 and 6681) .
Hypodigm – Type; a skull much deformed by dorsoventral flattening, most of the upper maxilla being incomplete ( Fig. 23A View FIGURE 23 ), together with the proximal phalanges of digits II and III (MLP-37-III-7-8), type of Onactornis depressus Cabrera, 1939 ; right tarsometatarsus, without the inner trochlea and a large part of the hypotarsus (MNHN-M-189, Fig. 2F View FIGURE 2 ), type of Devincenzia gallinali (Kraglievich, 1932) ; fragment of the madibular symphysis (MACN-6933), described by Kraglievich (1931) as Phororhacos? aff. platygnathus; proximal portion of a right femur, with the head missing (MACN-6930); distal portion of the left tibiotarsus (MACN-13243).
Horizon and Locality – Upper Miocene to the Lower Pliocene of Argentina, Provinces of Buenos Aires and Entre Rios (Huayquerian and “Mesopotamian”) and Uruguay (Arroyo Roman?).
Measurements – Table 6; Kraglievich, 1931; Patterson & Kraglievich, 1960.
Ilustrations – Kraglievich (1931 and 1932) and Cabrera (1939).
Remarks – Tambussi et al. (1999) described an almost complete right tibiotarsus (MNHN-M-1563) about 720 mm long, coming from the Raigon Formation (Pliocene) of south Uruguay. In this specimen the cnemial crests are extremely large and cranially projected, in a similar way to what occurrs in Titanis walleri (UF-7333), and different from what occurs with Brontornithinae . This tibiotarsus should be assigned to the genus Devincenzia and very probably to D. pozzi by the characters of a Phorusrhacinae , the size, age and geographic distribution. Unfortunatelly there is no sufficient material for a definite comparison. Another question would be a better definition of the difference in age between the sediments of the Raigon Formation of Uruguay with the Huayquerian and “Mesopotamian” of Argentina, as well as a new study on the possibility that the tarsometatarsus type of D. gallinali (Kraglievich, 1932) , may have also been collected in the Raigon Formation and not in the Arroyo Román as supposed by Kraglievich (1932).
