This article is a palynological study of four clay samples from the dinosaur-bearing Wealden facies at Baudour (Belgium). Their microflora is compared to that found at Bernissart. The palynomorphs of the four samples are of continental origin. The botanical affinities of the palynological taxa are mainly ferns, gymnosperms and freshwater "algae". Also encountered are stratigraphically important angiospermous-like pollen grains (biorecord Superret-croton, probable paleotaxon Superret-subcrot and biorecord Retisulc-dentat); the aperture of the former is questioned ("variant forms").
