About: Eocardiidae

An Entity of Type: insect, from Named Graph: http://dbpedia.org, within Data Space: dbpedia.org

The Eocardiidae are an extinct family of caviomorph rodents from South America. The family is probably ancestral to the living family Caviidae, which includes cavies, maras, and capybaras and their relatives. McKenna and Bell (1997) divided eocardiids into two subfamilies, for two of the oldest genera ( and ) and for remaining genera. Kramarz (2006) has recommended the abandonment of these subfamilies, as the genera placed in Luantinae appear to represent basal eocardiids, rather than a specialized side branch. The latter hypothesis had been proposed by Wood and Patterson (1959).

  • The Eocardiidae are an extinct family of caviomorph rodents from South America. The family is probably ancestral to the living family Caviidae, which includes cavies, maras, and capybaras and their relatives. McKenna and Bell (1997) divided eocardiids into two subfamilies, for two of the oldest genera ( and ) and for remaining genera. Kramarz (2006) has recommended the abandonment of these subfamilies, as the genera placed in Luantinae appear to represent basal eocardiids, rather than a specialized side branch. The latter hypothesis had been proposed by Wood and Patterson (1959). Fossils of the family were found in the Colhuehuapian to Friasian , Sarmiento, Santa Cruz, and Collón Curá Formations of Argentina and the Cura-Mallín Group of Chile. (en)
