Paranisolambda is an extinct genus of proterotheriid litopterns from the Early to Middle Eocene of Brazil . Fossils of Paranisolambda have been recovered from the Itaboraí Formation in the Brazilian state of Rio de Janeiro.[1]
Etymology
The genus name, Paranisolambda, is derived from the Greek para/παρα meaning "beside" or "near", and its close relative Anisolambda, the genus it was originally assigned to. The specific name, "prodromus" is derived from the Greek word prodromos, meaning "forerunner".[2]
History
The first remains of Paranisolambda were found in the Sāo José De Itaboraí Basin in 1948, consisting of the right mandible of a young individual as the holotype.
