Gravisaurus
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

Datos curiosos
Gravisaurus was first described in 1988 by paleontologist Souad Chabli in her PhD thesis, but the name was not officially published until 1999.21
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

?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
