Aeolosaurus was a huge, long-necked plant eater that lived in South America near the end of the Age of Dinosaurs. It walked on four sturdy legs and probably used its long neck to reach leaves high in the trees.6

趣味知識

Aeolosaurus lived between about 83.6 and 66 million years ago, during the Campanian and Maastrichtian ages of the Late Cretaceous.2

It belonged to a group called Aeolosaurini, which is part of the larger titanosaur family. Its closest relatives include Baurutitan, Caieiria, Gondwanatitan, and Panamericansaurus.6

Scientists have named two species: Aeolosaurus rionegrinus, the type species, and Aeolosaurus colhuehuapensis.6

Aeolosaurus fossils have been found in rocks from the Turonian to Santonian ages in central Brazil, which is older than the Campanian-Maastrichtian fossils from Argentina. This shows the genus lived over a long time and a wide area.1

The discovery of Aeolosaurus in the Marilia Formation of Brazil shows that this dinosaur survived after a marine incursion flooded parts of northern Patagonia during the Campanian-Maastrichtian.1

Aeolosaurus had special bones in its tail: the prezygapophyses (joints) curved downward on the front tail vertebrae, and the haemal arches had double articular facets set in a concave surface. This unique combination helps scientists identify it.6

關於 Aeolosaurus 最常被問的問題

?How big was Aeolosaurus?

Estimates vary. Gregory S. Paul said Aeolosaurus rionegrinus was about 14 metres (46 ft) long and weighed 6 tonnes (6.6 short tons). In 2020, Molina-Pérez and Larramendi gave a larger estimate of 18.1 metres (60 ft) and 14.7 tonnes (16.2 short tons).4 5

?What did Aeolosaurus eat?

Aeolosaurus was a herbivore, meaning it ate plants. Like other sauropods, it used its long neck to reach leaves high in trees.4 5

?When did Aeolosaurus live?

Aeolosaurus lived during the Late Cretaceous Period, from about 83 to 66 million years ago. Its fossils are found in rocks from the Campanian and Maastrichtian ages.4 6

?Where was Aeolosaurus found?

Aeolosaurus fossils have been found in Argentina and Brazil. In Argentina, they come from the Allen, Angostura Colorada, Lago Colhué Huapí, and Los Alamitos Formations. In Brazil, they are from the Serra da Galga Formation.4 5

迷思破解王

迷思： Some people think Aeolosaurus was a type of marine reptile because its name sounds like 'Aeolus' from the sea.

真相： Aeolosaurus was a land-dwelling dinosaur, a sauropod that lived on land and ate plants. It was not a marine reptile.6

發現: Aeolosaurus was named by J. E. Powell in 1987. The name comes from the Late Cretaceous fauna of Los Alamitos in Patagonia, Argentina, where the first fossils were found.6
仍有爭議: Scientists debate whether Gondwanatitan faustoi is a separate valid genus or a junior synonym of Aeolosaurus. One study says it is valid, but other classifications have placed it as a sister taxon.1 6
