Antarctopelta

名字的意思： “Antarctic shield”1

吃：植物甲龍類白堊紀晚期

Antarctopelta was an armoured dinosaur that lived in Antarctica during the Late Cretaceous. It was covered in bony plates and spikes, and its tail ended in a weapon made of fused spikes that looked like an Aztec club. It was a slow-moving plant-eater that used its armour for protection.1

趣味知識

Antarctopelta was the first dinosaur fossil ever named from Antarctica, even though it was discovered before another Antarctic dinosaur called Cryolophosaurus.1

Its tail had a special weapon called a macuahuitl, made of flat, spiky bones fused together. It looked like an Aztec club and was used for defence.1

Scientists found six different types of armour plates on Antarctopelta, including large flat ones and tall keeled spikes.1

Antarctopelta lived in a warm, ice-free Antarctica with dense forests of conifers, cycads, and ginkgos. It still had to survive long dark winters.1

The only known skeleton was discovered in 1986 by Argentine geologists Eduardo Olivero and Robert Scasso, but it took ten years to dig out because of frozen ground and bad weather.1

Antarctopelta shared its home with the small plant-eater Trinisaura, as well as marine reptiles like mosasaurs and plesiosaurs.1

關於 Antarctopelta 最常被問的問題

?How big was Antarctopelta?

About 4 meters (13 feet) long from snout to tail tip. One scientist estimated it could have been up to 6 meters (20 feet) long and weighed 350 kilograms (770 pounds).1

?What did Antarctopelta eat?

It was a plant-eater. Its jaws had small, leaf-shaped teeth for chewing plants.1

?Did Antarctopelta have feathers?

No. It was an armoured dinosaur covered in bony plates and spikes, not feathers.1

?When did Antarctopelta live?

It lived during the late Campanian stage of the Late Cretaceous period, about 73.4 million years ago.1

?Was Antarctopelta a dinosaur?

Yes, it was a type of armoured dinosaur called an ankylosaur.1

?Could Antarctopelta swim?

Scientists are not sure, but its body was stocky and built for walking on land, not swimming. Its fossils were found with a shark tooth, suggesting it may have floated out to sea after death.1

迷思破解王

迷思： Some people think Antarctopelta had a tail club like a typical ankylosaur.

真相： Antarctopelta actually had a macuahuitl, a flat fan of spikes at the end of its tail, not a round club.1

發現: Antarctopelta was discovered in January 1986 by Argentine geologists Eduardo Olivero and Robert Scasso on James Ross Island, Antarctica. It was named in 2006 by paleontologists Leonardo Salgado and Zulma Gasparini, who called it Antarctopelta oliveroi after Olivero.1
仍有爭議: Scientists are still debating whether Antarctopelta was more closely related to nodosaurids or ankylosaurids, because it has features of both groups.1
