Crested Screamer (Chauna torquata)

Magpie Goose (Anseranas semipalmata), sole survivng member of a Mesozoic lineage

Reconstruction of Dromornis stirtoni, a mihirung

• عائلة Anhimidae: screamers
• عائلة Anseranatidae: the Magpie Goose
• Family Anatidae
  • تحت عائلة Dendrocygninae: Whistling ducks (sometimes given full family status as the Dendrocygnidae).
  • تحت عائلة Thalassorninae: the White-backed Duck.
  • تحت عائلة Anserinae: Swans and geese.
  • تحت عائلة Stictonettinae: the Freckled Duck.
  • تحت عائلة Plectropterinae: the Spur-winged Goose.
  • تحت عائلة Tadorninae: Shelducks and sheldgeese - probably paraphyletic
  • تحت عائلة Anatinae: Dabbling ducks and moa-nalos
  • تحت عائلة Aythyinae: Diving ducks (sometimes included in Anatinae)
  • تحت عائلة Merginae: eiders, scoters, mergansers and other sea-ducks.
  • تحت عائلة Oxyurinae: Stiff-tailed ducks and allies.
• عائلة Dromornithidae (fossil): mihirungs
• عائلة Presbyornithidae (fossil): several genera of wading-"geese"

The fossil Gastornithidae (diatrymas) are also occasionally included herein as a family.

Some fossil anseriform taxa not assignable with certainty to a family are:

• Anatalavis (Late Cretaceous/Early Paleocene - Early Eocene) - Anseranatidae or basal. Includes "Telmatornis" rex.
• Proherodius (London Clay Early Eocene of London, England) - Presbyornithidae?
• Romainvillia (Late Eocene/Early Oligocene) - Anseranatidae or Anatidae
• Paranyroca (Rosebud Early Miocene of Bennett County, USA) - Anatidae or own family?

• Apatornis (Smoky Hill Chalk Late Cretaceous of Twin Butte Creek, USA)
• Vegavis (Late Cretaceous) - closer to Presbyornithidae and Anatidae than to Anseranatidae
• "Presbyornithidae" gen. et sp. indet. (Barun Goyot Late Cretaceous of Udan Sayr, Mongolia) - Presbyornithidae?
• UCMP 117599 (Hell Creek Late Cretaceous of Bug Creek West, USA)
• Petropluvialis (Late Eocene of England) - may be same as Palaeopapia
• Agnopterus (Late Eocene - Late Oligocene of Europe) - includes Cygnopterus lambrechti
• "Headonornis hantoniensis" BMNH PAL 4989 (Hampstead Early Oligocene of Isle of Wight, England) - formerly "Ptenornis"
• Palaeopapia (Hampstead Early Oligocene of Isle of Wight, England)
• "Anas" creccoides (Early/Middle Oligocene of Belgium)
• "Anas" skalicensis (Early Miocene of "Skalitz", Czechia)
• "Anas" risgoviensis (Late Miocene of Bavaria, Germany)
