After the taxonomic revision of the macroflora from Cervera (Lleida, Spain) of the 'Martí Madern' (Museu de Geologia de Barcelona and Museu Comarcal de Cervera collections). We present here their palaeoecological and palaeoclimatic study.
A likely model of the vegetation existing in the area in the low Oligocene is established by comparison with the models existing today of similar content and structure. Similar models are presently located in tropical regions about 20o latitude North.
The main vegetal community that has been found corresponds to the tropical deciduous forest. In superior wetter levels, evergreen forest with laurisilva communities appears.
The climate in the early Oligocene in the region was probably of the tropical kind, with a long dry period followed by a rain period. The average temperature would be around 22o - 26o.
Key words: Palaeobotany, Macroflora, Oligocene, Palaeoecology, Palaeoclimatology, Ebro Basin, Cervera, Spain.
