izinto ezimnandi

Iinyani ezimnandi

Bonitasaura had a sharp, beak-like keratin sheath on its lower jaw, which worked like a guillotine to cut plants.1

Its neck was short compared to other sauropods, and it had strong back vertebrae for muscle attachment, suggesting it used its neck vigorously while feeding.1

Bonitasaura's skull was low and long, similar to diplodocids, and its lower jaw was squared off with comb-like teeth.1

The front limbs were shorter than the hind limbs, unlike most other macronarians.1

Fossils of Bonitasaura show signs of diseases, including a tumour in the thigh bone and an infection in a tail bone.1

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

?How big was Bonitasaura?

Bonitasaura measured about 10 metres (33 feet) in length.1

?Did Bonitasaura have a beak?

Yes, Bonitasaura had a sharp, beak-like keratin sheath on its lower jaw that helped it to cut plants.1 4

?What did Bonitasaura eat?

Bonitasaura was a plant-eater. It used its peg-like front teeth to rake plants into its mouth and its sharp beak to cut them.1

?Where did Bonitasaura live?

Bonitasaura lived in what is now Argentina, in the Río Negro Province of Patagonia.1

Inyaniso ngeentsomi

Intsomi: Some people think Bonitasaura had a long neck like other sauropods.

Inyaniso: Bonitasaura actually had a relatively short neck, which is unusual for a sauropod.1

Inikwe igama ngu:: Apesteguía 20045
Iqela: Iintamo-nde
Usapho / iclade: Eutitanosauria5
Ukuhlelwa: Sauropodomorpha > Sauropoda > Titanosauria > Macronaria5
Ubudala bamatye: 86 ukuya ku-84 izigidi zeminyaka (Santonian)5
Izakhiwo zamatye: Bajo de la Carpa5
Amazwe: i-Argentina5
Iirekhodi zeefosili: 2 kwi-Paleobiology Database5
Ukufunyanwa: Bonitasaura was named by Sebastian Apesteguía in 2004, based on a partial skeleton found in the Bajo de la Carpa Formation in Argentina.1 3
Kusaxoxwa ngayo: Scientists still debate exactly where Bonitasaura fits in the titanosaur family tree, with different studies placing it in different groups.2 1
