First bird remains from the Upper Cretaceous of the Peirópolis site,
Minas Gerais state, Brazil.
Geodiversitas 34 (3) : 617-624

We report on the first occurrence of Maastrichtian bird material from
the Peirópolis locality (Uberaba district), Minas Gerais State
(Brazil). The specimens consist of an indeterminate pedal ungual
phalanx (CPP 481), a pedal phalanx 1 of left digit II (CPP 470) and an
incomplete metatarsal III (CPP 482). The material can be assigned to
Aves gen. et sp. indet. (CPP 470 and CPP 481) and to cf.
Enantiornithes gen. et sp. indet. (CPP 482). Despite the isolated and
incompleteness nature of these specimens, they add to the otherwise
poor record of Cretaceous birds from Brazil.
