Abstract

The vertebrate microfossil assemblages can provide important informations to paleoenvironmental and paleoecological reconstructions. However, taphonomic aspects need to be analyzed because the fossilization processes affect the quality of information found on the fossil record. The Solimões Formation (Upper Miocene) has yielded a rich fauna that includes mollusks, turtles, crocodiliforms, squamates, birds and mammals. Although a significant amount of studies about the age, geology and taxonomic composition of Solimões Formation has been conducted, there are still few studies about the taxonomy and taphonomy of vertebrate microfossils. The present study aims to describe the fauna of microvertebrates from two fossiliferous sites of the Solimões Formation (Acre Basin), and investigate the taphonomic processes involved in the formation of these sites. The proposed project will provide new contributions to more refined paleoecological and paleoenvironmental reconstructions of the Upper Miocene deposits of the Solimões Formation. (AU)
