Yayitya: IzityaloIzitya-zityalo ezinemilomoiCretaceous yokuqala

Gravisaurus was a heavy, plant-eating dinosaur that lived in what is now Niger, Africa, about 112 million years ago. It had a small head, a long neck, a round body, and strong front legs with big claws. Scientists think it moved slowly and may have looked a bit like a giant ground sloth.1

izinto ezimnandi

Iinyani ezimnandi

Gravisaurus was first described in 1988 by paleontologist Souad Chabli in her PhD thesis, but the name was not officially published until 1999.2 1

Its thumb spike was huge, much bigger than in other iguanodonts.1

Gravisaurus may have been the first ornithischian dinosaur with graviportal anatomy, meaning its legs were built to support a very heavy body.1

Its stomach was only about 70 centimetres (2 feet 4 inches) off the ground when it stood on all fours.1

Gravisaurus lived in a forested river environment alongside other dinosaurs like Ouranosaurus, Nigersaurus, and the giant crocodile Sarcosuchus.1

Some scientists think Gravisaurus behaved like a hippopotamus, spending time in water and moving slowly on land.1

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

?How big was Gravisaurus?

Gravisaurus was about 7 to 9 metres (23 to 30 feet) long and 2 metres (6.6 feet) tall on all fours. It weighed between 2.5 and 5.5 tonnes (2.8 to 6.1 short tons), which is as heavy as a large hippo.3

?What did Gravisaurus eat?

Gravisaurus was a plant-eater. It lived in a forested area with soft plants like ferns and horsetails, which it likely ate.3

?Did Gravisaurus have any predators?

Yes, Gravisaurus lived alongside big meat-eaters like the spinosaurid Suchomimus and the carcharodontosaurid Eocarcharia. Its huge thumb spike was probably used for defense.3

?Could Gravisaurus swim?

Some scientists think Gravisaurus may have behaved like a hippo, spending time in water. Its heavy body and strong legs suggest it could move in rivers, but nobody knows for sure if it swam.3

?Why did Gravisaurus have a thumb spike?

Gravisaurus had a massive thumb spike that scientists think was used for defense against predators.3

?Is Gravisaurus a dinosaur?

Yes, Gravisaurus is a dinosaur. It is a type of iguanodont ornithischian dinosaur from the Early Cretaceous period.3

Igama lenzululwazi: Gravisaurus
Inikwe igama ngu:: Chabli 19884
Iqela: Izitya-zityalo ezinemilomo
Usapho / iclade: Iguanodontoidea4
Ukuhlelwa: Ornithischia > Ornithopoda > Iguanodontia4
Ubudala bamatye: 113 ukuya ku-100 izigidi zeminyaka (Albian)4
Iirekhodi zeefosili: 1 kwi-Paleobiology Database4
Ukufunyanwa: The first skeleton of Gravisaurus was found in 1965 by French paleontologist Philippe Taquet in the Tenere desert of Niger. It was named Gravisaurus tenerensis by Souad Chabli in 1988, but later renamed Lurdusaurus arenatus in 1999.1 2
Kusaxoxwa ngayo: Scientists disagree on how heavy Gravisaurus was. One estimate says about 5.5 tonnes, while another says only 2.5 tonnes.1
