Xenoceratops
Xenoceratops was an early horned dinosaur that lived in Canada about 78 million years ago. It had a big frill on its head with spikes and two long horns above its eyes, making it look a bit like an alien. It was one of the oldest large horned dinosaurs ever found in North America.1

ເລື່ອງໜ້າຮູ້ມ່ວນໆ
Xenoceratops is the oldest known ceratopsid dinosaur from Canada, living about 78 million years ago.2
Its name means 'alien horned face' because it was found in rocks that had not yielded horned dinosaur fossils before.2
The fossils were collected in 1958 by paleontologist Wann Langston Jr., but they sat in a museum for decades before scientists realized they belonged to a new species.1
Unlike Triceratops, Xenoceratops had spikes on its frill in addition to the two long brow horns.1
Xenoceratops was about 6 metres long and weighed more than 2 tons, about as heavy as a large rhinoceros.1
It lived in a subtropical environment in Alberta, which at that time had no snow or frost.1
Scientists think Xenoceratops is the most primitive centrosaurine, meaning it branched off early in the evolution of this group of horned dinosaurs.2
ໄຂຄວາມເຊື່ອຜິດ
ຄວາມເຊື່ອຜິດ: Xenoceratops is just a small, unimportant dinosaur.
ຄວາມຈິງ: Xenoceratops is important because it is the oldest known large horned dinosaur from Canada, and it shows that horned dinosaurs evolved their fancy frills and horns very early.1
