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[edit]

* "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.

## Timeline[edit]

This is a timeline of selected dinosaurs from the list above. Time is measured in Ma, megaannum, along the x-axis.
