Incomplete K/Pg boundary transition (Relleu 3). The K/Pg hardground contains abundant ferromanganese, cherty nodules, marking a hiatus from Maastrichtian to Oligocene (relleu-3)



Relleu-1 outcrop. Hammer head (handle is 35 cm) rests on the impact layer. At the tip of the handle is the hard limestone indicating a bloom of calcareous dinoflagelates (Thoracosphaera). This layer occurs at all sections just above the eugubina zone in the Spanish Betic continental margin

There are several outcrops of the K/Pg boundary. Only two adjacent outcrops, Relleu 1 and 2, along the road CV755 are complete biostratigraphically.
