Nigersaurus taqueti

Nigersaurus is a fascinating dinosaur that lived about 110 to 105 million years ago during the middle Cretaceous period. It was a relatively small, herbivorous dinosaur and is part of the sauropod group, which includes giant, long-necked dinosaurs like Brachiosaurus and Apatosaurus. However, unlike those massive sauropods, Nigerosaurus was much smaller and more specialized in its diet.

One of its most distinctive features was its incredibly broad, flat mouth, which resembled a vacuum cleaner. Its teeth were adapted to grazing on low-lying plants, especially ferns. The structure of its jaw suggests it might have had a very efficient way of stripping vegetation close to the ground.

Nigerosaurus was discovered in the late 1990s in the Sahara Desert of Niger, which is where its name comes from. The fossils were well-preserved, and paleontologists learned a lot from them, including its strange and unique dental arrangement
