Echimyidae is one of the most speciose and ecologically diverse rodent families in the
world, occupying a wide range of habitats in the Neotropics. However, a resolved phylogeny …

Caviomorph rodents are one of the most diverse mammalian groups in the Neotropics; they
display astonishing eco-morphological variation, including unparalleled size range. Here we …

We analyse the taxonomic status and diversity of the late Miocene Octodontoidea
(Hystricognathi) Cercomys primitiva and related samples, a taxon previously known only …

The South American Ctenomys is the most speciose genus among both hystricomorphs and
subterranean rodents of the world. Here, we present the most exhaustive phylogenies and …

Brain morphological variation is analysed through virtual endocasts in a highly diversified
clade of caviomorph rodents belonging to the family Echimyidae. Diversification in brain size …

Rodents are the most diverse order of extant mammals, and caviomorph rodents, or New
World hystricognaths, have a remarkable morphological disparity and a long fossil record …

Abstract We describe new Late Miocene mammalian specimens from the Maimará
