吃：植物劍龍類侏羅紀晚期到白堊紀早期

Kentrosaurus was a plated dinosaur that lived in what is now Tanzania, Africa, about 152 million years ago. It had a row of small plates on its neck and back that turned into long, sharp spikes on its tail. It used those tail spikes to fight off hungry meat-eaters!1

酷東西

趣味知識

Kentrosaurus had a long spike on each shoulder, in addition to the spikes on its tail.1

The name Kentrosaurus was almost changed because it sounded like Centrosaurus, a horned dinosaur. But the spelling is different, so Kentrosaurus stayed.1

Scientists think there were two types of Kentrosaurus, one with stouter thigh bones and one with slimmer ones. This might mean males and females looked different.1

Over 1200 bones of Kentrosaurus were found in Tanzania by German expeditions between 1909 and 1912.1

Kentrosaurus lived alongside giant long-necked sauropods like Giraffatitan and Tornieria.1

The plates on its neck and back were probably covered in horn, like a cow's horn.1

你們都在問

關於 Kentrosaurus 最常被問的問題

?How big was Kentrosaurus?

Kentrosaurus was about 4 to 5 metres (13 to 16 feet) long and weighed roughly 700 to 1,600 kilograms (1,500 to 3,500 pounds). Some specimens suggest even larger individuals existed.1 3

?What did Kentrosaurus eat?

Kentrosaurus was a herbivore, meaning it ate plants. It used its toothless beak to bite off leaves and other plant material, which it swallowed in large chunks without much chewing.1 4

?Did Kentrosaurus have spikes?

Yes, Kentrosaurus had a double row of spikes along its back, from its mid-section to the tip of its tail, plus a long spike on each shoulder. These spikes were likely used for defense.1 4

?Could Kentrosaurus swim?

There is no direct evidence that Kentrosaurus could swim. It was a land-dwelling dinosaur that walked on four legs, and its body was not specially adapted for swimming.1

?Was Kentrosaurus bigger than a T. rex?

No, Kentrosaurus was much smaller than Tyrannosaurus rex. Kentrosaurus was about 4 to 5 metres long, while T. rex could be over 12 metres long; they lived in different times and places.1

?Did Kentrosaurus have feathers?

No, Kentrosaurus did not have feathers. It had bony plates and spikes covered in horn, and its skin was likely scaly, like other stegosaurs.1

?When did Kentrosaurus live?

Kentrosaurus lived during the Late Jurassic period, about 152 million years ago, in what is now Tanzania, Africa.1

?Why did Kentrosaurus have plates?

The plates on Kentrosaurus's neck and back might have been for temperature regulation, since they contained blood vessels, or for protection and display. No one knows for sure.4

迷思破解王

迷思： Some people think Kentrosaurus had all its spikes and plates in a single row down its back.

真相： Scientists think Kentrosaurus had two rows of plates and spikes, one on each side of its back.1
