| The Pliocene sedimentary marine deposits located in the western Canary Island (Gran Canaria, Fuerteventura and Lanzarote) are an open window to the Neogene ecological and climatic conditions in the North Western Atlantic, a crucial moment in the Earth?s evolution. The marine fauna present in the coastal outcrops from this age shows a climate conditions warmer than current ones. Some of those fossils works as paleoecological indicators, as the genus of marine gastropods Persististrombus and Nerita or the coral Siderastraea currently living in the tropical waters of eastern and western Atlantic, In Gran Canaria, Pliocene beaches appear associated with pillow lavas in the sites of Barranco de Tamaraceite and La Esfinge, dated in 4.8 and 4.2 million years respectivelly (Meco et al., 2015). In Barranco Seco outcrops, at about 95 m above the current sea level, within medium to fine grain size grey sands, with abundant bioturbation, fossilized seagrass remains have been found. Those fossil samples, the first from the West Africa coast, have been conferred to the genus Halodule. This genus of seagrass is currently confined to tropical waters of the eastern Atlantic: Nigeria, Benin, Ghana, Sierra Leone, Guinea, Guinea Bissau, Sao Tomé and Principe and Cape Verde Island (Green and Short, 2003), same current locations of others Pliocene Canary Island?s climatic paleoindicators. | |
