List of Australian and Antarctic dinosaurs

Valid genera

Name	Year	Formation	Location	Notes	Images
Antarctopelta	2006	Snow Hill Island Formation (Late Cretaceous, Campanian)	Antarctica	Possessed unusual caudal vertebrae that may have supported a "macuahuitl" as in Stegouros[1]
Atlascopcosaurus	1989	Eumeralla Formation (Early Cretaceous, Aptian to Albian)	Australia	Only known from remains of jaws and teeth
Australotitan	2021	Winton Formation (Late Cretaceous, Cenomanian to Turonian)	Australia	The largest dinosaur known from Australia, comparable in size to large South American dinosaurs
Australovenator	2009	Winton Formation (Late Cretaceous, Cenomanian)	Australia	Analysis of its arms suggest it was well-adapted to grasping[2]
Austrosaurus	1933	Allaru Formation (Early Cretaceous, Albian)	Australia	Its holotype was found associated with marine shells
Cryolophosaurus	1994	Hanson Formation (Early Jurassic, Pliensbachian)	Antarctica	Had a distinctive "pompadour" crest that spanned the head from side to side
Diamantinasaurus	2009	Winton Formation (Late Cretaceous, Cenomanian)	Australia	May have been closely related to South American titanosaurs, suggesting they dispersed to Australia via Antarctica[3]
Diluvicursor	2018	Eumeralla Formation (Early Cretaceous, Albian)	Australia	Lived in a prehistoric floodplain close to a high-energy river
Fostoria	2019	Griman Creek Formation (Late Cretaceous, Cenomanian)	Australia	Four individuals have been found in association
Fulgurotherium	1932	Griman Creek Formation (Late Cretaceous, Cenomanian)	Australia	Fragmentary, but may have been an elasmarian[4]
Galleonosaurus	2019	Wonthaggi Formation (Early Cretaceous, Barremian)	Australia	Its upper jaw bone resembles a galleon when turned upside-down
Glacialisaurus	2007	Hanson Formation (Early Jurassic, Pliensbachian)	Antarctica	Basal yet survived late enough to coexist with true sauropods[5]
Imperobator	2019	Snow Hill Island Formation (Late Cretaceous, Maastrichtian)	Antarctica	Unusually for a paravian, it lacked an enlarged sickle claw
Kakuru	1980	Bulldog Shale (Early Cretaceous, Aptian)	Australia	Poorly known
Kunbarrasaurus	2015	Allaru Formation, Toolebuc Formation (Early Cretaceous to Late Cretaceous, Albian to Cenomanian)	Australia	Preserves stomach contents containing ferns, fruits, and seeds[6]
Leaellynasaura	1989	Eumeralla Formation (Early Cretaceous, Albian)	Australia	One referred specimen has an extremely long tail; if it does belong to this genus, it would be three times as long as the rest of the body
Minmi	1980	Bungil Formation (Early Cretaceous, Aptian)	Australia	Had long legs for an ankylosaur, possibly to help it run into bushes for protection[7]
Morrosaurus	2016	Snow Hill Island Formation (Late Cretaceous, Maastrichtian)	Antarctica	Closely related to Australian and South American ornithopods[4]
Muttaburrasaurus	1981	Allaru Formation?, Mackunda Formation (Early Cretaceous to Late Cretaceous, Albian to Cenomanian)	Australia	Possessed a short oval bump on its snout
Ozraptor	1998	Colalura Sandstone (Middle Jurassic, Bajocian)	Australia	Potentially the oldest known abelisauroid[8]
Qantassaurus	1999	Wonthaggi Formation (Early Cretaceous, Barremian)	Australia	Distinguished from its other contemporary ornithopods by its relatively short dentary
Rapator	1932	Griman Creek Formation (Early Cretaceous to Late Cretaceous, Albian to Cenomanian)	Australia	Known from only a metacarpal
Rhoetosaurus	1926	Walloon Coal Measures (Late Jurassic, Oxfordian)	Australia	Retains four claws on its hind feet, a basal trait
Savannasaurus	2016	Winton Formation (Late Cretaceous, Cenomanian to Turonian)	Australia	May have spent more time near water than other sauropods[9]
Serendipaceratops	2003	Wonthaggi Formation (Early Cretaceous, Barremian to Albian)	Australia	Possessed a robust ulna similar to those of ceratopsians and ankylosaurs, but was likely a member of the latter group[10]
Timimus	1993	Eumeralla Formation (Early Cretaceous, Albian)	Australia	Potentially a tyrannosauroid;[11] if so it would be one of the few Gondwanan members of that group
Trinisaura	2013	Snow Hill Island Formation (Late Cretaceous, Campanian)	Antarctica	The first ornithopod named from Antarctica
Weewarrasaurus	2018	Griman Creek Formation (Late Cretaceous, Cenomanian)	Australia	Unusually, its fossils were preserved in opal
Wintonotitan	2009	Winton Formation (Early Cretaceous to Late Cretaceous, Albian to Cenomanian)	Australia	More gracile than other contemporary titanosaurs

Invalid and potentially valid genera

• 
  "Allosaurus" "robustus"
• 
  Walgettosuchus

• Agrosaurus macgillivrayi: Although originally reported as being from Australia, it may actually be from Europe, possibly being synonymous with Thecodontosaurus.
• "Allosaurus robustus": Originally described as a new species of Allosaurus, but may actually represent a megaraptoran or abelisauroid.
• "Biscoveosaurus": Said to be a large ornithopod contemporary with Morrosaurus.
• Walgettosuchus woodwardi: It has been considered synonymous with Rapator, but too little is known of both genera to be certain.
