Opisthocoelicaudia

Igama lithetha: “posterior cavity tail”1

Yayitya: IzityaloIintamo-ndeiCretaceous yamva

Opisthocoelicaudia was a big, long-necked plant eater that lived in the Late Cretaceous. It had a barrel-shaped body and four thick legs, like an elephant. Scientists found a nearly complete skeleton without the head and neck, so they know a lot about its body.1

izinto ezimnandi

Iinyani ezimnandi

Its tail vertebrae were shaped like ball-and-socket joints, which is unusual and gives it the name 'posterior cavity tail'.1

The skeleton had tooth marks from big meat-eating dinosaurs, which probably ate the carcass and carried away the head and neck.1

It could probably rear up on its hind legs to reach higher food, because its tail was strong and could act like a tripod.1 2

Its back vertebrae had split spines, creating a double row of bumps along its spine, a feature also seen in Diplodocus.1

It had six hip vertebrae, one more than most sauropods, which made its hips extra strong.1

The neck was about 5 meters (16 feet) long, which is medium for a sauropod.1

Kukuqikelela nje: esona silwanyana sinokuba sasikhangeleka ngenye indlela, kwaye akukho mntu waziyo imibala yaso yokwenyani.

ubuzile

Eyona mibuzo ibuzwa kakhulu: Opisthocoelicaudia

?How big was Opisthocoelicaudia?

It was a relatively small sauropod, measuring about 11.4 to 13 metres (37 to 43 feet) long. Its body mass has been estimated at between 8.4 and 25.4 tonnes in different studies.1

?What did Opisthocoelicaudia eat?

Like other sauropods, it was a herbivore that ate plants. It probably fed on a variety of vegetation in its floodplain and riverine environment.3

?When did Opisthocoelicaudia live?

It lived during the Late Cretaceous Period, specifically in the ?Upper Campanian or Lower Maastrichtian, about 72 to 66 million years ago.1 2

?Where was Opisthocoelicaudia found?

Its fossils were discovered in the Gobi Desert of Mongolia, in the Nemegt Formation. The type specimen was found at Altan Uul in Ömnögovi Province.1

?Could Opisthocoelicaudia rear up on its hind legs?

Yes, scientists think it could rear up on its hind legs to reach higher food. Its strong tail could act like a tripod to support its weight.1

?Is Opisthocoelicaudia a dinosaur?

Yes, it is a sauropod dinosaur. It belongs to the group Titanosauria and lived during the Late Cretaceous.1

Inyaniso ngeentsomi

Intsomi: Some people think Opisthocoelicaudia was a kind of camarasaur, but scientists now know it was a titanosaur.

Inyaniso: It was first classified as a camarasaurid, but later studies placed it in Titanosauria, a group of sauropods.1

Izakhiwo zamatye: Nemegt4
Amazwe: iMongolia4
Iirekhodi zeefosili: 1 kwi-Paleobiology Database4
Ukufunyanwa: It was discovered in 1965 by a Polish-Mongolian expedition in the Gobi Desert. Polish paleontologist Maria Magdalena Borsuk-Białynicka named it in 1977.1 2
Kusaxoxwa ngayo: Scientists debate whether Opisthocoelicaudia and Nemegtosaurus are actually the same species, because only the skull of Nemegtosaurus is known and Opisthocoelicaudia lacks a skull.1
