Imigrantes em um continente perdido: O registro fossilífero de roedores Caviomorpha (Mammalia: Rodentia: Ctenohystrica) do Cenozoico do Brasil

Abstract: Rodentia é um dos grupos de mamíferos placentários mais diversificados. Representantes desse clado possuem uma ampla distribuição geográfica, ocupando todos os continentes, com exceção da Antártida. Entre as diversas linhagens que compõem Rodentia, destacam-se os Caviomorpha, um grupo de origem sul-americana. Caviomorfos surgem no registro fossilífero durante o Eoceno médio, passando por diversos períodos de diversificação ao longo do Cenozoico, principalmente durante o final do Oligoceno e Mioceno médio/final… Show more

“…Rodents are the most numerous and diverse group of mammals today, inhabiting varied climates, environments and ecological niches, from forests to deserts (Kerber, 2017). Brazil presents a great diversity of rodents, and according to Kerber (2017), South American rodents include Caviomorpha (15 families or more), Myomorpha (Cricetidae and Sciuridae) and Castorimorpha (Heteromyidae and Geomyidae).…”

Brazil presents a great diversity of rodents, and according to Kerber (2017), South American rodents include Caviomorpha (15 families or more), Myomorpha (Cricetidae and Sciuridae) and Castorimorpha (Heteromyidae and Geomyidae). Caviomorpha are represented by the superfamily Cavioidea, which comprises some of the largest rodents in the world, including the families Dasyproctidae (agoutis), Cuniculidae (pacas), Caviidae (capybaras and guinea pigs) and Dinomyidae (pacaranas).…”
