Amanzia was a long-necked plant-eater that lived in what is now Switzerland about 157 million years ago. It was a small sauropod, not much longer than a school bus, and it munched on leaves and ferns. Its bones were found in an old quarry near the town of Moutier.1 2

酷東西

趣味知識

Amanzia was first thought to be a different dinosaur called Ornithopsis, and later Cetiosauriscus, before scientists gave it its own name in 2020.1 2

The fossils include bones from at least four different individuals, some of which were different sizes.1

Amanzia had a special rough patch on the back of its upper arm bone that no other sauropod has.1

Its tail bones were long and had small holes for blood vessels.1

The bones were found in a greenish layer of marl and limestone, which was once a muddy seafloor.1

Amanzia is one of the few sauropods known from Switzerland, and its discovery helped scientists understand European dinosaurs better.1

發現: The first bones were found in the 1860s in a quarry near Moutier, Switzerland. In 1922, German scientist Friedrich von Huene named them Ornithopsis greppini. In 2020, a new study gave them the new genus name Amanzia, after Swiss geologist Amanz Gressly.1 2
仍有爭議: Scientists are not sure whether Amanzia was a member of the group Turiasauria or just a close relative of all later sauropods.1
