吃：植物長脖子恐龍白堊紀晚期

Arrudatitan was a huge, long-necked plant-eater that lived in Brazil during the Late Cretaceous. It was a titanosaur, a group of sauropods that included some of the biggest land animals ever. Even though it was giant, Arrudatitan was more slender and graceful than many of its relatives.1

酷東西

趣味知識

Arrudatitan was first thought to be a species of Aeolosaurus, but scientists later gave it its own genus name in 2021.1 2

The first fossils were found in 1997 by a farmer and his 12-year-old nephew in a field in Cândido Rodrigues, Brazil.1

Its femur (thigh bone) was 1.55 metres (5.1 feet) long, which helps scientists estimate its total length at about 15 metres (49 feet).1

Crocodylomorph and theropod teeth were found near the Arrudatitan skeleton, but there were no bite marks on the bones.1

Arrudatitan lived during the Campanian to Maastrichtian stages of the Late Cretaceous, about 72 to 68 million years ago.1

The name Arrudatitan honors Brazilian paleontologist Antônio Celso de Arruda Campos.1

發現: The first fossils were found in 1997 by Ademir Frare and his 12-year-old nephew Luiz Augusto dos Santos Frare in a field in Cândido Rodrigues, Brazil. They told paleontologist Antônio Celso de Arruda Campos, and the bones were collected by staff of the Museu de Paleontologia de Monte Alto. The species was first named Aeolosaurus maximus in 2011, but moved to its own genus Arrudatitan in 2021.1
仍有爭議: Scientists are still debating exactly how Arrudatitan is related to other titanosaurs, and whether it belongs in the group Rinconsauria or is closer to other South American giants.1 4
