A middle Miocene decapod faunule from Granada (Spain), with remarks on distribution pattern of the crab Portunus monspeliensis
A decapod crustacean faunule is reported from the middle Miocene strata cropping out near Murchas (Granada Basin, southern Spain). The association consists of the brachyuran crab Portunus monspeliensis and primarily the axiidean shrimp Eucalliax sp. Based on calcareous nannoplankton, the age of the association is estimated to be late Langhian (MNN5a zone). The preservation of decapod remains suggests only some transport if any prior to burial. The depositional setting of the studied strata is interpreted as shallow marine, not exceeding 30 m in depth. The presence of P. monspeliensis in the Granada Basin links the roughly coeval Mediterranean populations with those from the Atlantic.
