–Engl. summ. Describes new material from the "Oligo-Miocene" (actually Early Miocene) of Brazil, including the first complete fossil sir. skull found in South America. These specimens were here referred to Sirenotherium pirabense, which was in turn referred to the Dugongidae; however, they were later redescribed as Dioplotherium cf. allisoni by Toledo & Domning (1991).
ABSTRACT--The Pirabas Formation on the Atlaniic coast of Par?, Brazil, is evidently of late Early Miocene (Burdigalian) age. It has recently yielded material of three genera of dugongid sirenians: Dioplotherium cf. D. allisoni and Rytiodus (Subfamily Rytiodontinae), and cf. Metaxyltherium (Subfamily Halitheriinae). If the specimen tentalively referred to Rytiodus is correctly identified, this is the first record of the genus in the New World. S?renotherium p?rabense, based on material previously reported from the Pirabas Formation, is a nomen dubium. The new discoveries include the most complete fossil sirenian remains yet discovered in South America, and show that Early Miocene sirenian diversity on the Atlantic coast of South America was comparable to that which existed contemporaneously in North America.
