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
