Nigersaurus

Nigersaurus was about 9 to 14.1 metres long and weighed around 1.9 to 4 tonnes, about as heavy as a modern elephant.4

Nigersaurus ate soft plants like ferns, horsetails, and possibly angiosperms. It was a ground-level browser, gathering and slicing soft vegetation with its wide mouth.42

Nigersaurus lived during the Early Cretaceous period, about 121 to 99 million years ago, specifically around 115 to 105 million years ago.14

Nigersaurus was found in the Elrhaz Formation in an area called Gadoufaoua, in Niger, Africa. It is also known from Algeria and Tunisia.41

Nigersaurus had more than 500 teeth in its wide muzzle. It replaced them very quickly, about every 14 days, which is faster than most other dinosaurs.4

Yes, Nigersaurus was a sauropod dinosaur, specifically a rebbachisaurid sauropod. It belonged to the group Diplodocoidea.41

Nigersaurus had a wide, flat mouth that faced straight down, perfect for cropping soft plants close to the ground. It was like a vacuum cleaner for ferns and horsetails.42

Nigersaurus replaced its teeth very rapidly, about once every 14 days, which is about twice as fast as hadrosaurid dinosaurs.42

No, Nigersaurus was generally smaller than T. rex. It was about 9 to 14.1 metres long, while T. rex was about 12 to 13 metres long, but Nigersaurus was lighter, weighing only 1.9 to 4 tonnes compared to T. rex's 7 to 8 tonnes.4

No, Nigersaurus was a sauropod dinosaur, and sauropods did not have feathers. It had scaly skin, like other reptiles.4
