摘要: ABSTRACT Detailed records of spore-pollen assemblages from four sites located in the Aliaga and Oliete Sub-basins provide new insights into palaeoclimatic palaeogeographic settings during Albian-Cenomanian transition Maestrazgo Basin (northeastern Spain). Palynological taxa such as Afropollis jardinus Doyle, Jardine & Doerenkamp, 1982, Elaterosporites klaszii (Jardine Magloire) Jardine, 1967, Equisetosporites ambiguus (Hedlund 1966) Singh, 1983, Gabonisporis pseudoreticulatus Boltenhagen, Senectotetradites varireticulatus Dettmann, 1973, Stellatopollis barghoornii 1975, dinoflagellate cyst Cyclonephelium chabaca Below, 1981 indicate a latest Albian age for this unit. Abundance Gondwanan elements 1967 1975 indicates northward extension paleogeographic distributions those time. Comparison between studied microflora Iberi...
