A new species of Gaylordia Paula Couto (Mammalia, Metatheria) from Itaboraí, Brazil

We describe a new metatherian of the genus Gaylordia Paula Couto, from the early Eocene Itaboraí Basin, Brazil. This new species (estimated body mass ~60-90.9 g) is based on lower and upper dentition elements and is characterized by a more plesiomorphic dental morphology with respect to G. macrocyno...

This new species (estimated body mass ~60-90.9 g) is based on lower and upper dentition elements and is characterized by a more plesiomorphic dental morphology with respect to G. macrocynodonta Paula Couto (with a larger body mass, estimated in ~74-103 g for large individuals or males). The species G. doelloi Marshall, represented by small individuals or females, is regarded a junior synonym of G. macrocynodonta. A phylogenetic analysis as well as details of the occlusal surface of its upper and lower molars suggests that Gaylordia is closely related to the Pucadelphyidae, a non-marsupial “ameridelphian” group previously recorded at the early Paleocene locality of Tiupampa, Bolivia.Descreve-se um novo marsupial basal do gênero Gaylordia Paula Couto, do Eoceno inicial da bacia de Itaboraí, Brasil. Esta nova espécie (massa corporal estimada ~60-90.9 g) está baseada na dentição superior e inferior, e é caracterizada por uma morfologia dentária mais plesiomórfi ca em relação a G. macrocynodonta Paula Couto (cuja maior massa corporal é estimada em ~74-103 g para grandes indivíduos ou machos). A espécie G. doelloi Marshall, representada por indíviduos pequenos ou fêmeas, é considerada um sinônimo junior de G. macrocynodonta. Uma análise fi logenética, bem como detalhes da superfície oclusal de seus molares superiores e inferiores sugerem uma relação próxima de Gaylordia aos Pucadelphyidae, um grupo de ameridélfi os não marsupiais previamente registrados no Paleoceno inicial da localidade de Tiupampa, Bolivia.Fil: Oliveira, Édison Vicente.
