吃：植物角龍類白堊紀晚期

Montanoceratops was a small, plant-eating dinosaur with a beak and a bony frill on its head. It lived in North America during the Late Cretaceous, about 72 million years ago. This dinosaur is part of a group called leptoceratopsids, which were like smaller cousins of the famous Triceratops.1

趣味知識

Montanoceratops was first thought to be a species of Leptoceratops, but in 1951 it got its own genus name.1

The nose horn of Montanoceratops was actually a misidentified cheekbone, which fooled paleontologists for years.1

Montanoceratops lived alongside bigger horned dinosaurs, but it was smaller and had a deeper tail.1

Fossils of Montanoceratops have been found in rocks that are between 83.6 and 66 million years old.3

Montanoceratops is part of a group called leptoceratopsids, which were diverse and lived in the same habitats as the bigger ceratopsids.1

關於 Montanoceratops 最常被問的問題

?How big was Montanoceratops?

Montanoceratops was a small dinosaur, about 2.5 metres (8.2 feet) long and weighed around 170 kilograms (370 pounds).2

?What did Montanoceratops eat?

Montanoceratops was a herbivore, meaning it ate plants. It used its sharp beak to bite off leaves or needles.2

?Did Montanoceratops have a horn?

It was once thought to have a horn on its nose, but that bone was later identified as a misplaced cheek horn. So it did not have a nose horn.2 1

?Where did Montanoceratops live?

Montanoceratops lived in what is now Montana, USA, and Alberta, Canada, about 70 million years ago.2

迷思破解王

迷思： Montanoceratops had a prominent nose horn like some other horned dinosaurs.

真相： The supposed nose horn was actually a misidentified cheekbone, so Montanoceratops likely did not have a nose horn.1

發現: Barnum Brown and Erich Schlaikjer described the first fossil in 1942, but they called it Leptoceratops cerorhynchos. In 1951, Charles M. Sternberg realized it was different and named it Montanoceratops.1
仍有爭議: Scientists still debate exactly how Montanoceratops is related to other horned dinosaurs, especially because some fossils were misidentified.1
