Puffinus be divided in what has been called the "Puffinus" and the "Neonectris" group after notable species; the latter has been separated as a distinct genus named "Ardenna". The former is taxonomically confusing, with species having been split and remerged in the last years. The genus "Puffinus" contains the following species: Several fossil species which became extinct long ago are also known. The proportion of larger ("Neonectris") species apparently was larger before the Pliocene, i.e. before marine mammals diversified: ""Puffinus" arvernensis" (Early Miocene of France) is now considered a primitive albatross of the fossil genus "Plotornis". Puffinus Puffinus is a genus
Dune shearwater which bred in lava fields. Extinction of the species occurred about 2000–3000 years ago, contemporaneously with the first human settlement of the islands by the Guanches, with the cause likely to be human predation. Dune shearwater The dune shearwater ("Puffinus holeae"), also known as the Canarian shearwater or Hole's shearwater, was a relatively large shearwater which bred in the Canary Islands archipelago of the North Atlantic Ocean. Fossils have also been found in the Figueira Brava cave archaeological site on the western coast of Portugal. The specific epithet honours Mrs Jean Hole who collected fossil material of the species on
