Austrodyptornithes is a clade of birds that include the orders Sphenisciformes (penguins) and Procellariiformes (tube-nosed seabirds).[1] A 2014 analysis of whole genomes of 48 representative bird species concluded that penguins are the sister group of Procellariiformes,[2] from which they diverged about 60 million years ago.[3]


Spheniscidae (penguins)


Diomedeidae (albatrosses)

Oceanitidae (Austral or southern storm petrels)

Hydrobatidae (northern storm petrels)

Pelecanoididae (diving petrels)

Procellariidae (fulmarine petrels, gadfly petrels, prions, shearwaters)
