Taxonomy

Two species, F. buelli and F. goedertorum (Barnes et al. 1995). F. buelli is of early Oligocene (Rupelian) age, while F. goedertorum is younger. The latter was originally described as a species of Chonecetus before it was recognized as more closely related to buelli than to the Choncetus type species.[2][3]

Biology

The tooth structure of Fucaia indicates that it was capable of both raptorial feeding and suction-feeding, like other aetiocetids.
