Abstract
We describe a cycadeoid trunk from the Aptian Chickabally Member, Budden Canyon Formation in Ono, California. Our diagnosis of the specimen as a cycadeoid was initially based on the presence of mucilage canals in the pith and the structure of the secondary xylem. This determination was subsequently supported by recognition of the distinctive morphology of the surface of the primary body of eroded cycadeoid trunks. The latter may aid in the identification of otherwise enigmatic Mesozoic fossils. This specimen is the third cycadeoid to be reported from northern California and slightly extends the known geographic range of the group within the state.
