酷東西

趣味知識

Pelorosaurus was one of the first sauropods to be identified as a dinosaur, but Richard Owen had earlier thought its bones belonged to a giant sea crocodile.1

Its front legs were relatively long, a trait typical of brachiosaurids, which helped it reach high vegetation.1

The name 'Pelorosaurus' was originally going to be 'Colossosaurus', but the scientist changed it because 'kolossos' meant 'statue' in Greek, not 'giant'.1

Many fossils once assigned to Pelorosaurus have turned out to belong to other dinosaurs, like Haestasaurus and Duriatitan.1

The humerus (upper arm bone) of Pelorosaurus was 137 centimeters long, which is taller than most adult humans.1

Pelorosaurus lived about 140 to 125 million years ago, during the Early Cretaceous period.1 2

真相： Scientists now know it was a land-dwelling dinosaur, thanks to its leg bones that supported its weight on land.1

給恐龍專家

學名: Pelorosaurus
命名者: Mantell 18504
類群: 長脖子恐龍
科 / 演化支: Titanosauriformes4
分類: Sauropodomorpha > Sauropoda > Macronaria4
岩石的年代: 145 到 110 百萬年 (Tithonian / Albian)4
岩層: Tunbridge Wells Sand4

化石紀錄: The Paleobiology Database 收錄 3 筆4
發現: Gideon Mantell named Pelorosaurus in 1850, based on bones found in England. He used a humerus and vertebrae that had been discovered earlier, and he was the first to suggest it was a dinosaur.1 4
仍有爭議: Scientists still debate whether Pelorosaurus is a valid genus, because the original bones might belong to more than one animal, and the name has a confusing history.1
