酷東西

趣味知識

Hollanda is known only from its hind leg bones, so scientists have to guess what the rest of its body looked like.1

Its foot had a special toe arrangement called anisodactyl, with the first toe turned sideways, which helped it run and perch.1

Hollanda lived about 83 to 72 million years ago, during the Campanian age of the Late Cretaceous.4

Even though Hollanda was a fast runner on the ground, it evolved from ancestors that lived in trees.1

Hollanda is part of a group called Ornithuromorpha, which includes modern birds and their close relatives.4

關於 Hollanda 最常被問的問題

?Was Hollanda a dinosaur?

Yes, Hollanda was a small bird-like dinosaur called an avialan theropod. It is not a modern bird but a close relative that lived in the Cretaceous period.2 4

?How big was Hollanda?

Hollanda was about the size of a turkey, with long legs. Scientists estimate it was roughly 60 to 80 centimetres (2 to 2.6 feet) tall, based on its leg bones.2 3

?What did Hollanda eat?

Hollanda was a ground-dwelling carnivore that ate insects and small animals. It likely chased its prey on foot, similar to a modern roadrunner.2 4 3

迷思破解王

迷思： Some people think Hollanda was a dinosaur like T. rex.

真相： Hollanda was a bird, not a non-avian dinosaur. It is an avialan, which means it is more closely related to modern birds than to dinosaurs like T. rex.4
