酷東西

趣味知識

Cumnoria was first thrown on a rubbish heap by brick pit workers before a scientist rescued the bones.1 2

It was originally thought to be a species of Iguanodon, then Camptosaurus, before being recognized as its own genus.1 2

Cumnoria may be the oldest known member of a group called Styracosterna, which includes more advanced duck-billed dinosaurs.1

The only known skeleton is a juvenile, because its vertebrae and ribs were not fully fused together.1

Cumnoria had a special ridge on its shoulder bone and an oval muscle scar on its upper arm that are unique among its relatives.1

迷思破解王

迷思： Cumnoria is just a young Camptosaurus.

真相： Scientists now think Cumnoria is a separate genus, not a baby Camptosaurus, based on unique features in its bones.1 2

發現: Workers at Chawley Brick Pits in 1879 found the bones on a dump heap. They were given to Professor George Rolleston, then to Joseph Prestwich, who reported it as a new Iguanodon. John Whitaker Hulke named it Iguanodon prestwichii in 1880. Harry Govier Seeley gave it the genus Cumnoria in 1888.1 2
仍有爭議: Scientists still debate whether Cumnoria is a distinct genus or should be lumped back into Camptosaurus.1 2
