名字的意思： “bird-likeness”1

吃：植物長脖子恐龍侏羅紀晚期到白堊紀早期

Ornithopsis was a huge, long-necked plant-eater that stomped through England and Germany during the Early Cretaceous. Its name means 'bird-likeness' because its back bones were hollow and filled with air sacs, just like birds have today.1

酷東西

趣味知識

Ornithopsis was one of the first dinosaurs whose bones were recognized as having air sacs, like modern birds and pterosaurs.1

The only known species is Ornithopsis hulkei, named after the scientist John Whitaker Hulke.1

Its back bones were very light because they were filled with big cavities called camellae.1

Scientists think Ornithopsis was about 16 to 18 metres long, as long as two school buses.1

A possible German fossil of Ornithopsis came from a slightly smaller individual.1

Ornithopsis belongs to a group of sauropods called Titanosauriformes, which includes some of the biggest land animals ever.1

發現: Harry Govier Seeley named Ornithopsis in 1870 based on two vertebrae from the Isle of Wight, England. He thought it was a creature between pterosaurs and birds, but later scientists showed it was a sauropod dinosaur.1
仍有爭議: Scientists are not sure if the German fossil really belongs to Ornithopsis because it is poorly preserved.1
