Gannets and Boobies are medium to large-sized seabirds of mostly coastal regions that typically feed on fish by plunge-diving. They haven't changed much compared to their extinct relatives, of which the oldest date from the Eocene of Europe.
Distribution & Fossil evidence
During the Eocene, the family lived in Europe with several genuses known to science. Some of of these species, like Masillastega, lived in inland freshwater environments instead of coastal regions. During the Miocene, the family spread Asia and the Americas.
The family consists of several extinct and still extant species of Gannets and Boobies.
