Resumen:
Antarctica presents one of the most severe environmental conditions for life. Under these circumstances, cryptogams are thedominant photosynthetic organisms, among which we fnd a great richness of lichens. In Antarctic environments, lichens cangrow on rocks or in this case on fossil remains, among the few available substrates. In the present contribution, we examinedall fossil penguins of the Antarctic collection of the Museo de La Plata, as a signifcant sample of fossil vertebrates. Theselected materials here described come from the Submeseta Formation (Eocene) on Seymour/Marambio Island, locatednortheast of the Antarctic Peninsula on the Weddell Sea. Given the scarcity of lichenological studies on this island, andthe results presented here add signifcantly to our knowledge of the lichen species that occur there with the recognition of11 taxa with a crustose morphology (epilithic and endolithic), the sampling of lichens growing on fossil bones acquired anevident importance.
