Akainacephalus

Igama lithetha: “thorny head”1

Yayitya: IzityaloIidayinaso ezinesikrweqeiCretaceous yamva

Akainacephalus was an armored dinosaur that looked like a living tank. It had a bony club at the end of its tail and a head covered in spiky, pyramid-shaped bumps. This dinosaur lived in what is now southern Utah, USA, about 76 million years ago.1 3

izinto ezimnandi

Iinyani ezimnandi

Akainacephalus is the most complete ankylosaurid dinosaur ever found from the southern part of ancient Laramidia.1

Its skull was covered with raised, cone-shaped and pyramid-shaped bony plates called caputegulae.1

This dinosaur had a massive tail club made of two large bones fused together.1

Akainacephalus lived about 76 million years ago during the Campanian stage of the Late Cretaceous.1

Its closest relatives include Nodocephalosaurus from New Mexico and Asian ankylosaurids like Saichania.1

The only known specimen was discovered in a bonebed that also contained fossils of other animals.1

Umfanekiso owenziwe yi-AI: Akainacephalus — Umfanekiso owenziwe yi-AI obonisa indlela Akainacephalus esenokuba wayekhangeleka ngayo, wenziwe yikhompyutha ngokwento eyaziwa zizazinzulu. Kukuqikelela nje: esona silwanyana sinokuba sasikhangeleka ngenye indlela, kwaye akukho mntu waziyo imibala yaso yokwenyani.

ubuzile

Eyona mibuzo ibuzwa kakhulu: Akainacephalus

?How big was Akainacephalus?

Scientists do not know its exact size because no complete skeleton has been found. The only known specimen includes about 45% of the skeleton, so its total length and weight are still uncertain.2 1

?What did Akainacephalus eat?

Akainacephalus was a plant-eater. Like other ankylosaurids, it had a narrow, U-shaped beak and teeth suited for cropping and chewing tough plants.2

?Did Akainacephalus have a tail club?

Yes. Akainacephalus had a complete tail club made of two large bones fused together, which it could have used for defense.2 1

?Where was Akainacephalus found?

Akainacephalus was discovered in southern Utah, USA, in the Kaiparowits Formation of the Grand Staircase, Escalante National Monument. The site is called the Horse Mountain Gryposaur Quarry.2 1

Inyaniso ngeentsomi

Intsomi: Akainacephalus could roll into a ball like an armadillo.

Inyaniso: No ankylosaur could roll into a ball. Akainacephalus defended itself with its bony armor and tail club.1
