Dinosaurs 500 teeth

That nickname was given to the African dinosaur Nigersaurus taqueti — back when some new discoveries about its appearance were made public in

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.

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. The jaws may have borne a keratinous sheath. 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. Its skeleton was highly pneumatised filled with air spaces connected to air sacs , but the limbs were robustly built. Nigersaurus and its closest relatives are grouped within the subfamily Rebbachisaurinae formerly thought to be grouped in the eponymous Nigersaurinae of the family Rebbachisauridae, which is part of the sauropod superfamily Diplodocoidea.

A new carnivore While walking across a very flat area, Gabe made a remarkable find—the bones dinosaurs 500 teeth a new meat-eating dinosaur lay partially exposed at her feet.

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.

Nigersaurus had a wide muzzle filled with more than slender teeth, which were replaced at a rapid rate of around every 14 days. With over teeth packed into its wide mouth, the Nigersaurus dinosaur was truly a marvel of natural engineering. Yet this bizarre, plant-eating creature remains lesser known compared to its more famous tyrannosaurus and triceratops cousins. First discovered in the African country of Niger, Nigersaurus has nonetheless captured the imagination of paleontologists seeking to unravel the mysteries of the dinosaur world. How did this unusual dinosaur use its plethora of teeth? What evolutionary niche did it occupy with such distinctive dental anatomy? As one of the most extreme dinosaurs adapted for specialized feeding, the toothy tale of Nigersaurus provides a fascinating glimpse into prehistoric diversity. Nigersaurus was a sauropod , a group known for their large size and long necks, but it stood out from its relatives due to its distinct dental structure. What sets the Nigersaurus apart is its jaw structure, housing more than slender teeth. These teeth were not only numerous but also remarkably arranged.

But they're rare among the sauropods. Alamosaurus Baurutitan? Nigersaurus vertebrae took this to an extreme. Studies released in and found that the position of the LSC can't reliably tell us what any given sauropod's normal head posture looked like. The first known fossils belonging to this animal were recovered during the s by French paleontologists in the Nigerian Sahara. Biological Reviews. Early Cretaceous Dinosaurs. We hope to find more evidence of this sharp-toothed creature as the field season goes on. That gave them a good look at the lateral semicircular canal LSC of the inner ear, which helps animals keep their balance. Kotasaurus Ohmdenosaurus Rhoetosaurus Sanpasaurus?

Dinosaurs have always fascinated us with their extraordinary features, and one particularly intriguing species stands out — the dinosaur with an astonishing teeth. In this exploration, we delve into the mystery surrounding this unique prehistoric creature and answer the questions that many curious minds have pondered.

Cretaceous Research. Zoological Journal of the Linnean Society. 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. Dinosaur-hunters are used to finding dental batteries in beaked herbivores like the horned Triceratops and shovel-billed Edmontosaurus. The width of the muzzle and lateral orientation of the tooth row show that the sauropod could gather much food and crop it close to the ground, within 1 m 3 ft 3 in of the surface. What's a dinosaur to do with chompers like this animal's teeth? Gandititan Hamititan Huabeisaurus Jiangshanosaurus? Toggle limited content width. They consisted of vertically stacked columns of replaceable teeth. Viewed from above, Nigersaurus' wide muzzle looks like the business end of one of these household appliances. Nature Communications.
