Article: Mid-Cretaceous angiosperm pollen from southern England and northern France

Angiosperm pollen grains are described from the Upper Albian to Middle Cenomanian strata of several localities in southern England and northern France. Twenty-two species are described, of which the following thirteen are new: Psilatricolpites rectilatibus, Retitricolpites amplifissus, R. crassitransennus, R. exiguiexemplum, R. meumendum, R. promiscuus, R. sarthensis, R. subtilimaculatus, Psilatricolporites complanatius, Retitricolporites ecommoyensis, R. insolitimorus, Triporopollenites curtisi, and T. worbarrowensis, A sequence of angiosperm pollen assemblages is suggested and an attempt is made to relate this to the ammonite zonation.
