Hallazgo de un endocarpo del genero Acer en niveles del Cretacico superior del embalse de Pedrezuela (Guadalix de la Sierra)

Abstract

Describes and discusses an endocarp of Acer genus that exhibits a morphology like the living species A. buergerianum Miquel. The fruit was found in the upper part of Cretaceous series from the Pedrezuela barrier of Madrid Community. A new denomination for the plant that contains this endocarp: Acer palaeobuergerianum n. fsp is proposed. This name has only taxonomic value. The prefix is given in order to the age and -buergerianum by its similarity with the actual species.
