That nickname was given to the African dinosaur Nigersaurus taqueti — back when some new discoveries about its appearance were made dinosaurs 500 teeth in What dinosaur has teeth?

Nigersaurus lived in a lush environment alongside the predatory dinosaur Suchomimus, the plant eaters ouranosaurus and lurdusaurus, and supercroc. Nigersaurus had a delicate skull and an extremely wide mouth lined with teeth especially adapted for browsing plants close to the ground. This bizarre, long-necked dinosaur is characterized by its unusually broad, straight-edged muzzle tipped with more than replaceable teeth. The original fossil skull of Nigersaurus is one of the first dinosaur skulls to be digitally reconstructed from CT scans. Our first week in the field has been spectacular! Remarkable discoveries seem to be waiting for us around every dune.

He was excavating bones in a dry region called Gadoufaoua, which had a rich fossil bed first discovered by French uranium miners. There were a lot of light, aerated bones — usually associated with theropods, like Tyrannosaurus rex, and the birds that evolved from them — so the researchers assumed that was what they were dealing with. As Sereno began to piece together the fossils, he realized it must be a sauropod, or long-necked dinosaur. Most of the bones appeared fairly typical for long-necked dinosaurs —except for its bizarrely-shaped head. Eventually, back in the lab, Sereno had to ask for a second opinion from colleagues who worked on fossil fish and other reptiles before he figured it out. There are a lot of strange-looking dinosaurs out there. The sauropod's jaw looks almost like a large nail clipper, with large rows of hundreds of teeth on its upper and lower jaws. But compared to other sauropods, it was relatively small — sitting somewhere between an African and Indian elephant in size. The dinosaur's vertebrae was filled with air pockets similar to those of birds, so the dinosaur was likely quite light, as well. Its brain was about the size of a walnut, which is more or less average for sauropods, Sereno says. Its head is what really stands out about Nigersaurus , though. The jaws, which have a flat front, are lined with about teeth, which Sereno says were replaceable. These teeth were all the same in size, and he estimates that they probably only lasted about a month or so before they were worn down. These teeth and the shape of the sauropod's skull likely evolved to help it munch on plants low to the ground. All told, these were some of the most successful herbivores on the planet, Sereno says.

Adamantisaurus Maxakalisaurus? While other heavy animals examined such as rhinoceroses had thick and variable bone corticesthe cortex of Nigersaurus was rather thin. And no fewer than 68 very sharp teeth were present on the lower jaws, dinosaurs 500 teeth.

It was discovered in the Elrhaz Formation in an area called Gadoufaoua , in Niger. Fossils of this dinosaur were first described in , but it was only named Nigersaurus taqueti in , after further and more complete remains were found and described. The genus name means "Niger reptile", and the specific name honours the palaeontologist Philippe Taquet , who discovered the first remains. Small for a sauropod, Nigersaurus was about 9 m 30 ft long, and had a short neck. It weighed around 1. Its skull was very specialised for feeding, with large fenestrae and thin bones. It had a wide muzzle filled with more than teeth, which were replaced at a rapid rate: around every 14 days.

When it comes to dinosaurs, one of the most fascinating aspects is their teeth. From the fearsome Tyrannosaurus Rex with its large, sharp teeth to herbivorous dinosaurs with flatter, grinding teeth, these prehistoric creatures exhibit a wide range of dental arrangements. So, what dinosaur has teeth? The answer is the Nigersaurus. It lived during the middle Cretaceous period, approximately to million years ago. This dinosaur was first discovered in the Republic of Niger, from which it gets its name. The Nigersaurus is known for having more teeth than any other dinosaur discovered to date.

Igai Isisaurus? According to a study published in the journal PLOS One, Nigersaurus likely replaced each "new" tooth after just 14 days. It was distinct in that the tooth row expanded to the sides from the plane of the main ramus of the lower jaw. Protognathosaurus Schleitheimia Tuebingosaurus? This transverse orientation of the upper and lower tooth rows was unique to the dinosaur. An unorthodox herbivore, this reptile grazed in what's now the Sahara Desert million years ago. Back when this animal roamed, forests and braided rivers covered the landscape. Whenever the top tooth wore out in any given column, the one right below it would move upwards and take the old tooth's spot. Unlike other tetrapods , the tooth-bearing bones of its jaws were rotated transversely relative to the rest of the skull, so that all of its teeth were located far to the front. Inawentu Menucocelsior. Their ranks included the largest animals to ever walk the Earth. Other researchers have disputed this claim, though. The sauropod's jaw looks almost like a large nail clipper, with large rows of hundreds of teeth on its upper and lower jaws.

Wafer-thin fossils with thin bone plates aren't the easiest things to preserve and study. Agustinia Amazonsaurus Comahuesaurus Dzharatitanis? It had a prominent rugosity a roughly wrinkled area on the midline aspect of the scapular blade's base, a distinguishing feature. This was matched by an identical rotation of the dentary of the lower jaw. Alamosaurus Baurutitan? Magyarosaurus Malarguesaurus? Daanosaurus Dashanpusaurus? Retrieved 20 August Nearly all rebbachisaurids had relatively short necks and a length of 10 m 33 ft or less. We even laid out the team to get a sense of just how big this animal was.
