Primer registro fósil de la familia Trichomycteridae (Teleostei: Siluriformes; Plioceno) en la Formación Monte Hermoso, Argentina

Resumen

First fossil record for the family Trichomycteridae (Teleostei: Siluriformes; Pliocene) in
the Monte Hermoso Formation, Argentina. Some fossil remains referable to the siluriform family
Trichomycteridae are described in this paper. These specimens exhibit a combination of characters that allow to
include them within the subfamily Trichomycterinae. These elements consist on an opercular and interopercular
of the same individual, collected in Lower-Middle Pliocene beds of the Monte Hermoso Formation, at the Farola
de Monte Hermoso locality, Buenos Aires province, Argentina. This record constitutes the first fossil remains
reported for the family, and one of the few paleoichthyological records for the Monte Hermoso Formation.
