Seabird in the Cretaceous, with a species called "Tytthostonyx glauconiticus", which seems allied to the Procellariiformes and Pelecaniformes. In the Paleogene both pterosaurs and marine reptiles became extinct, allowing seabirds to expand ecologically. These post-extinction seas were dominated by early Procellariidae, giant penguins and two extinct families, the Pelagornithidae and the Plotopteridae (a group of large seabirds that looked like the penguins). Modern genera began their wide radiation in the Miocene, although the genus "Puffinus" (which includes today's Manx shearwater and sooty shearwater) might date back to the Oligocene. The highest diversity of seabirds apparently existed during the Late Miocene and
Coat of arms of Saba Coat of arms of Saba The coat of arms of Saba was established in 1985 by the island council of Saba, when it was still part of the Netherlands Antilles. It remained the coat of arms of Saba after the dissolution of the Netherlands Antilles and the subsequent change of Saba's constitutional status into a special municipality of the Netherlands in 2010.

In the middle is a representation of the island itself, with a fish,
