The Sierra de Marmolance (SE Spain) offers a valuable record of Early–Middle Miocene larger benthic foraminifera (LBF) in limestones overlying and laterally changing to marls. Dating by planktonic foraminiferal assemblages in the marls entails significant changes in the last occurrence ages of some LBF used for dating shallow-water carbonates. Key findings include the record of Nummulites still living in the Indo-Pacific but thought to have disappeared in the fossil record at the end of the Oligocene.
