吃：植物長脖子恐龍白堊紀早期到白堊紀晚期

Sauroposeidon was one of the tallest dinosaurs that ever lived. It had an incredibly long neck that helped it reach high into trees to eat leaves. This giant plant-eater lived in North America during the Early Cretaceous period.1 2

趣味知識

Sauroposeidon's neck vertebrae were extremely long and light, filled with air sacs like a bird's bones.2

It lived about 113 to 110 million years ago, near the end of the Early Cretaceous.1

Sauroposeidon was one of the last sauropods in North America before a 40-million-year gap without them.1

The first fossils were four neck bones found in Oklahoma in 1994.1

Scientists once thought the Texas fossils were a separate dinosaur called Paluxysaurus, but now they are considered the same as Sauroposeidon.1

Sauroposeidon is the official state dinosaur of Texas.1

Its neck could reach about 11 to 12 meters (36 to 39 feet) long, letting it browse from treetops without moving its body.1

It lived about 113 to 110 million years ago, during the Early Cretaceous period.1

?Where was Sauroposeidon found?

Its fossils were found in the U.S. states of Oklahoma, Texas, and Wyoming.1

?Why did Sauroposeidon have such a long neck?

Its long neck helped it reach high into trees to eat leaves without moving its whole body, like a giraffe's neck.1

?Is Sauroposeidon a dinosaur?

Yes, it is a sauropod dinosaur, a type of long-necked plant-eater.1

迷思破解王

迷思： Sauroposeidon was the largest dinosaur ever.

真相： While very tall, Sauroposeidon was not the heaviest or longest. Other sauropods like Argentinosaurus were bigger overall.1
