Aquilarhinus

Igama lithetha: “eagle snout”1

Yayitya: IzityaloImilomo-dadaiCretaceous yamva

Aquilarhinus was a duck-billed dinosaur with a weird, shovel-shaped beak. It used its beak to scoop up soft plants from swamps and rivers. This dinosaur lived in what is now Texas, USA, about 80 million years ago.2 1

izinto ezimnandi

Iinyani ezimnandi

Aquilarhinus had a beak shaped like a shovel, which was different from the flat beaks of most duck-billed dinosaurs.1 2

Its lower jaw bones met in a W shape at the front, which helped it scoop up plants.2

The name Aquilarhinus means 'eagle snout' because its nose bones were arched like an eagle's beak.1

This dinosaur lived during the Campanian stage of the Late Cretaceous, between 83.6 and 72.2 million years ago.3

Aquilarhinus was first thought to be a species of Kritosaurus, but scientists later realized it was a new genus.1

Its fossils were found in the Aguja Formation in Texas, which was once a swampy coastal plain.2 1

Umfanekiso owenziwe yi-AI: Aquilarhinus — Umfanekiso owenziwe yi-AI obonisa indlela Aquilarhinus 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: Aquilarhinus

?How big was Aquilarhinus?

Scientists have not published a specific length or weight for Aquilarhinus, but as a hadrosaurid it was probably similar in size to other duck-billed dinosaurs, around 7 to 9 metres (23 to 30 feet) long.1

?What did Aquilarhinus eat?

It ate soft plants, scooping up semiaquatic vegetation from swamps and rivers with its shovel-shaped beak.1 2

?Why did Aquilarhinus have a shovel beak?

Its lower jaw bones met in a W shape, forming a wide, flattened scoop that helped it shovel out and scoop up loose, wet sediment and aquatic plants.1 2

?When did Aquilarhinus live?

It lived about 80 million years ago, during the Campanian stage of the Late Cretaceous.1

Inyaniso ngeentsomi

Intsomi: Some people think all duck-billed dinosaurs had flat, duck-like beaks.

Inyaniso: Aquilarhinus had a shovel-shaped beak, not flat like a duck's. It used it to dig and scoop plants.2

Ukuhlelwa: Ornithischia > Ornithopoda > Iguanodontia > Hadrosauridae4
Ubudala bamatye: 84 ukuya ku-72 izigidi zeminyaka (Campanian)4
Izakhiwo zamatye: Aguja4

Iirekhodi zeefosili: 1 kwi-Paleobiology Database4
Ukufunyanwa: The first fossil of Aquilarhinus was found in 1983 in Big Bend National Park, Texas. More bones were dug up in 1999. It was named Aquilarhinus palimentus in 2019 by scientists Prieto-Márquez, Wagner, and Lehman.1
Kusaxoxwa ngayo: Scientists are still debating exactly how Aquilarhinus used its shovel-shaped beak. It might have scooped plants from water or dug in mud.2
