名字的意思： “almond tooth”1 2

吃：植物長脖子恐龍侏羅紀早期

Amygdalodon was a huge, long-necked plant-eater that lived in Argentina during the Early Jurassic, about 180 million years ago. It was one of the very first sauropod dinosaurs ever found in South America, and scientists only know it from a single partial skeleton.1 2

酷東西

趣味知識

Amygdalodon means 'almond tooth' because its teeth are shaped like almonds.1 2

It was discovered in 1936 after a local scientist mentioned finding bones of a large reptile, and Dr. Tomás Suero went to look for more.1

The only known fossils include some vertebrae, ribs, teeth, and parts of the pelvis and shoulder blade.1

Amygdalodon lived about 180 to 172 million years ago, during the Toarcian stage of the Jurassic.1

It was a quadruped, meaning it walked on all four legs, like other sauropods.1

Scientists think Amygdalodon was a basal sauropod, meaning it was an early relative of the giant long-necked dinosaurs that came later.1

Some studies suggest it might be closely related to the Asian dinosaur Gongxianosaurus.1

關於 Amygdalodon 最常被問的問題

?How big was Amygdalodon?

Amygdalodon was about 12 metres (39 feet) long and 4 metres (13 feet) tall, and weighed over 5 tonnes (5.5 short tons). Estimates vary, with some sources suggesting a length of 15 metres (49 feet).1 2

?What did Amygdalodon eat?

Amygdalodon was a plant-eater, or herbivore. Its almond-shaped teeth show early signs of adapting for bulk feeding, which later sauropods used to eat lots of plants.1 2

?When did Amygdalodon live?

Amygdalodon lived during the Early Jurassic, about 180 to 172 million years ago. The Natural History Museum says Mid Jurassic, 177 to 169 million years ago, so the exact time is debated.1 2

?Where was Amygdalodon found?

Amygdalodon was found in Argentina, in the Cerro Carnerero Formation of Chubut Province. It was discovered in 1936 by Dr. Tomás Suero.1 2
