Where: Spain (28.1° N, 15.7° W: paleocoordinates 29.0° N, 15.8° W)
• coordinate estimated from map
• outcrop-level geographic resolution
When: Early/Lower Pleistocene (2.6 - 0.8 Ma)
• The magnetic polarity of the basaltic lava flow directly underlying the marine deposits at Los Llanos de Tumas (Agaete) is normal and has a K/Ar age of 1.80 +-0.03 Ma. The magnetic polarity of the basaltic lava flow overlying the deposits at Cementerio (Agaete) is reversed and the K/Ar age is 1.75 +-0.03 Ma. The two ages agree perfectly with their polarities and correspond to the upper limit of the Olduvai event.
• bed-level stratigraphic resolution
Environment/lithology: coastal; poorly lithified, calcareous conglomerate
Size class: macrofossils
