Finds from land mammals and reptiles, and birds were very rare. The extinct species Squalus smithi Herman, 1982b is redefined as a synonym for Squalus minor Daimeries, 1888, the validity of Squatina crassa Daimeries, 1889 is reinstated and the occurrence of Heterodontus in the North Sea basin during the Eocene is revised to one single species (see Migom & Hoedemakers in prep.).
