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
Ponta dos Rosais and agricultural areas, with most of the region taken-up by rural activities. Tourists visiting the area are attracted by the diversity of migratory and maritime bird species that nest in the cliffs of the point, including the migratory Corey's Shearwater ("Calonectris diomedea") and Little shearwater ("Puffinus assimilis"), but also the Roseate ("Sterna dougallii") and Common Terns ("Sterna hirundo"). Endemic predator species in these areas include feral cats and dogs, as well as rodents, but the latter limited by local kite species. But, the region is a hothouse of Azorean heather ("Erica azorica") and Forget-me-nots ("Myosotis azorica"). Ponta dos Rosais Ponta
