Jurassic plant macroremains from Portugal
Descrição
Mem. Acad. Ciências Lisboa, Classe Ciências, XXXVII: 25-47 General characterization of the Triassic and Jurassic environments as well as list of localities and taxa of plant macroremains of Portugal are presented. Cycadophytes and conifers, mainly from the Cheirolepidiaceae family, predominate. No recent studies have been carried out, the latest date from the 70's. Systematic position of some taxa is uncertain. A deep review is needed. The Upper Jurassic portuguese plant macroremains suggest warm and dry climates The commonest forms (Otozamites, Cupressinocladus) show thick cuticles and strongly protected stomata. Ferns are rather scarce and the pinnules are smaller than those of homologous forms of other regions i e. in Yorkshire (U.K.).
