Abstract

Accounts of the occurrence of angiosperms in pre-Albian (often Jurassic) beds are found in paleobotanical literature. These early finds are frequently based on a very interesting sporomorph Eucommiidites. In 1961, Hughes found Eucommiidites in the micropylar canals of gymnospermous seeds from the Wealden of England. In a sample from the Patuxent Formation (Neocomian-Aptian) from Virginia, hundreds of well preserved specimens of a seed species have been found. The well defined micropyle and pollen chamber leave no doubt of its gymnospermous affinity. In over 50% of the specimens, grains of Eucommiidites are found either in the micropylar canal or in the pollen chamber to the exclusion of other pollen types. The similarity of N.F. Hughes' findings from the Wealden of England and the Patuxent material leaves no doubt that Eucommiidites Erdtman should not be considered as evidence for the existence of pre-Albian angiosperms.
