Say it: WIN-ton-oh-TIE-tan

Name means: “Winton giant”1

Ate: PlantsLong-necksLate Cretaceous

Wintonotitan was a long-necked sauropod that lived in Australia about 100 million years ago. It was a plant-eater with a relatively slender body and front legs longer than its back legs. Scientists call it 'Clancy' after a poem by Banjo Patterson.2

Fun facts

Wintonotitan was one of three new dinosaurs named from the Winton Formation in 2009, along with Diamantinasaurus and Australovenator.1

Its fossils were first discovered in the 1970s by Keith Watts, who donated them to the Queensland Museum. The species name wattsi honors him.2

Wintonotitan had unique tail bones that were biconvex (rounded on both ends) near the tip, which is different from most other sauropods.2

It lived in a river plain environment with large rivers, swamps, and lakes, after the Eromanga Sea had retreated. The climate was subtropical with abundant rainfall.2

Wintonotitan was a relatively small titanosaur, reaching about 15 to 16 metres long, while some other titanosaurs could grow to 35 metres.2

The fossils found include most of the front limb and shoulder girdle, tail vertebrae, ribs, and hip bones, but no skull or teeth have been discovered yet.2

Most asked questions about Wintonotitan

?How much did Wintonotitan weigh?

About 10 to 15 tonnes (22,000 to 33,000 pounds). That is roughly as heavy as a large truck.2

?What plants did Wintonotitan eat?

It ate ferns, ginkgoes, conifers, cycads, and early flowering plants that grew in its river-plain home.2

?How did Wintonotitan get its name?

Its name means 'Winton titan', after the town of Winton in Queensland, Australia, where its fossils were found.3

?When did Wintonotitan live?

It lived during the Cretaceous Period, about 100 million years ago.2

For dino experts

Scientific name: Wintonotitan
Named by: Hocknull et al. 20094
Group: Long-necks
Family / clade: Diamantinasauria4
Classification: Sauropodomorpha > Sauropoda > Macronaria4
Age of the rocks: 100 to 90 million years (Cenomanian / Turonian)4
Rock formations: Winton4
Countries: Australia4
Fossil records: 7 in the Paleobiology Database4
Discovery: Wintonotitan was named by Scott Hocknull and colleagues in 2009 based on fossils found near Winton, Queensland. The bones were first collected in the 1970s by Keith Watts and later excavated by the Queensland Museum in the 1980s.1 2
Still debated: Scientists are not sure what Wintonotitan's skull looked like because no skull bones have been found. They also debate whether it was a basal titanosauriform or a more derived titanosaur.2 1
