Climatic reconstruction at the early Miocene La Rinconada mine
The materials of the La Rinconada mine (40°01′21″N 0°16′34″W) belong to the Ribesalbes sequence which unconformably overlies Cretaceous limestones (Anadón et al. 1990).The fossils studied were collected from laminated dolostones of unit B (up to 100 m thick) which resulted from deposition in anoxic bottom conditions in a meromictic lake (Anadón et al. 1989 Anadón et al. 1990).
