趣味知識

Serendipaceratops is known from just one bone, a left ulna (lower arm bone) that is about 16 centimetres long.1

The bone was discovered in 1993 during the Dinosaur Cove project, in a small area of sea-floor protected by a dam.1

Scientists first thought the bone might be from a theropod, but later noticed it looked like the arm bone of a horned dinosaur called Leptoceratops.1

The species name, arthurcclarkei, honors science fiction writer Arthur C. Clarke, who was a friend of the scientists that named it.1

Some scientists think Serendipaceratops might actually be an ankylosaur, not a horned dinosaur, because the arm bone is robust.1

The fossil was found in the Wonthaggi Formation, which is about 115 million years old.1

關於 Serendipaceratops 最常被問的問題

?What did Serendipaceratops eat?

Serendipaceratops was a herbivore, meaning it ate plants.1

?How big was Serendipaceratops?

Nobody knows for sure, because only one arm bone has been found. That bone is about 16 centimetres (6 inches) long.1

?When did Serendipaceratops live?

It lived during the Early Cretaceous Period, about 115 million years ago.1

?Was Serendipaceratops a dinosaur?

It is a type of ornithischian dinosaur, possibly an ankylosaur.1

?Why is it called Serendipaceratops?

The name means 'serendipitous horned face', because scientists were surprised to find a horned dinosaur bone in Australia. It was named by luck or serendipity.1

?Was Serendipaceratops a ceratopsian?

Scientists disagree. Some think it was a ceratopsian, but others think it was an ankylosaur because the arm bone is robust.1

迷思破解王

迷思： Some people think Serendipaceratops was definitely a horned dinosaur like Triceratops.

真相： Scientists are not sure. Some studies say it is a ceratopsian, but others say it might be an ankylosaur because the arm bone is robust.1

學名: Serendipaceratops
命名者: Rich and Vickers-Rich 20033
類群: 角龍類
科 / 演化支: Ceratopsia3
分類: Ornithischia > Ceratopsia3
岩石的年代: 121 到 120 百萬年 (Aptian)3

發現: The bone was found in 1993 near Kilcunda, Australia, and the dinosaur was named by Tom Rich and Patricia Vickers-Rich in 2003. The name came after a colleague pointed out the bone looked like a horned dinosaur's arm bone.1
仍有爭議: Scientists still debate whether Serendipaceratops is a ceratopsian or an ankylosaur, because only one bone is known and it may be deformed.1
