A fossil siluriform spine (Teleostei, Ostariophysi) from the Miocene of Chile
Maria de las Mercedes Azpelicueta, Alfonso Rubilar
Abstract
ABSTRACT. A fossil catfish spine of Siluroidei from fluviolacustrine upper beds of the Cura-Mallin Formation is described. This unit is assigned to the Miocene. The spine has generalized features that may preclude its precise identification, although it is possible to differentiate it from those of extant Siluriforms of Chile. RESUMEN. Una espina fosil de pez siluriforme (Teleostei, Ostariophysi) del Mioceno de Chile. En esta nota se describe una espina fosil de Siluroidei encontrada en unidades sedimentarias superiores, fluviolacustres de la Formacion Cura-Mallin, asignadas al Mioceno. El ejemplar tiene caracteres generalizados que impiden una identificacion taxonomica precisa, aunque es posible diferenciarla de las espinas de siluriformes actuales que habitan en Chile.
