Antarctica presents one of the most severe environmental conditions for life. Under these circumstances, cryptogams are the dominant photosynthetic organisms, among which we find a great richness of lichens. In Antarctic environments, lichens can grow on rocks or in this case on fossil remains, among the few available substrates. In the present contribution, we examined all fossil penguins of the Antarctic collection of the Museo de La Plata, as a significant sample of fossil vertebrates. The selected materials here described come from the Submeseta Formation (Eocene) on Seymour/Marambio Island, located northeast of the Antarctic Peninsula on the Weddell Sea. Given the scarcity of lichenological studies on this island, and the results presented here add significantly to our knowledge of the lichen species that occur there with the recognition of 11 taxa with a crustose morphology (epilithic and endolithic), the sampling of lichens growing on fossil bones acquired an evident importance.

南极洲始新世企鹅化石遗骸上生长的丰富地衣

南极洲是生命最恶劣的环境条件之一。在这种情况下，隐花是占优势的光合生物，其中我们发现了丰富的地衣。在南极环境中，地衣可以在岩石上或在这种情况下在化石遗骸上生长，这是少数可用的基质。在目前的贡献中，我们检查了拉普拉塔博物馆南极收藏的所有企鹅化石，作为脊椎动物化石的重要样本。此处描述的选定材料来自位于威德尔海南极半岛东北部的西摩/马兰比奥岛上的 Submeseta 地层（始新世）。鉴于岛上地衣学研究的稀缺性，
