Utuntu dushimishije

Fukuivenator is known from a nearly complete skeleton, making it the most complete non-bird dinosaur ever found in Japan.1 2

Its inner ear was shaped like a mix between those of birds and other dinosaurs, showing a step in the evolution of bird hearing.1 2

Fukuivenator had a very large nostril opening, almost as tall as another hole in its skull called the antorbital fenestra.1

This dinosaur had different kinds of teeth in its mouth, a feature called heterodonty. Some teeth were small and spatula-shaped, while others were large and curved.1

Scientists cannot place Fukuivenator into any known dinosaur group. It seems to be a very early member of the maniraptoran family, but with a unique mix of traits.1 2

The fossil was found in 2007 in a quarry near the Sugiyama River in Katsuyama, Japan. It was buried in rock that is about 121 to 113 million years old.1 3

Ibibazo bibazwa cyane kuri Fukuivenator

?How big was Fukuivenator?

Fukuivenator was about 2.45 metres (8.0 feet) long and weighed around 25 kilograms (55 pounds).4 1

?What did Fukuivenator eat?

Fukuivenator probably ate both plants and meat, like a modern raccoon. Its teeth and long neck suggest it was at least omnivorous, maybe even mostly herbivorous.4 1

?Where was Fukuivenator found?

Fukuivenator was found in 2007 in a quarry near the Sugiyama River in Katsuyama, Japan. The skeleton is the most complete non-bird dinosaur fossil ever found in Japan.4 1

?When did Fukuivenator live?

Fukuivenator lived during the Early Cretaceous, about 127 to 115 million years ago. That's based on radiometric dating of nearby rocks.4

?Did Fukuivenator have feathers?

No direct feather fossils are known for Fukuivenator, but it was a coelurosaurian theropod, a group that includes feathered dinosaurs. So it likely had feathers, though we can't be sure.4 1

?Why is Fukuivenator called a paradox?

Its species name 'paradoxus' means 'paradoxical' because it has a strange mix of features from different dinosaur groups, making it hard to classify. It's a puzzle for scientists.4 1
