Abstract

The first description of insect-plant interaction in a Glossopteris flora from the Permian of Argentina (La Golondrina Formation, Santa Cruz) is presented. Four specimens are described; these are referred to Glossopteris browniana (Brongniart), G. damudica (Feistmantel), and G. sp. cf. G. ampla Archangelsky. Different types of interaction recorded include marginal feeding and oviposition. This is the first evidence of insect-damage in the flora from the La Golondrina Formation, and also presently the only formal description of this kind available for a Paleozoic megaflora in Argentina.
