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".

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.
