Albertavenator

名字的意思： “Alberta hunter”1

Albertavenator was a small, fast, bird-like dinosaur that lived in Canada about 71 million years ago. It had a short, wide skull bone that made it different from other smart raptors. Scientists think it ate meat and maybe plants too.1 2

酷東西

趣味知識

Albertavenator is known only from a few skull bones, especially the frontal bone of the forehead.1

Its frontal bone is very short and wide, with a length-to-width ratio less than 1.3, shorter than any other known troodontid from the Late Cretaceous.1 2

The name Albertavenator means 'Alberta hunter' and honors paleontologist Philip J. Currie.1

It lived during the early Maastrichtian stage of the Late Cretaceous, about 71 million years ago.1

Its fossils were found in the Horseshoe Canyon Formation, which was a cool, swampy floodplain with redwoods and ferns.1

Albertavenator was a troodontid, a group of smart, bird-like raptors that had large brains and sharp claws.1

?How big was Albertavenator?

About the size of a person, based on comparisons with its close relative Troodon. It was a small-bodied troodontid.4 1

?Did Albertavenator have feathers?

?What did Albertavenator eat?

Scientists think it ate meat and maybe plants too, based on its teeth and jaw remains.1

?When did Albertavenator live?

It lived about 71 million years ago, during the Late Cretaceous period.1 4

迷思破解王

迷思： Some people think all troodontids were just one species called Troodon.

真相： Albertavenator shows that there were many different troodontid species in the Late Cretaceous, each with unique skull features.1 2
