Bizarre 500-toothed dinosaur
The first bones of Nigersaurus were collected in the 1950s by French paleontologists, though the species was not named until 1999 after Sereno's team member Didier Dutheil spotted skull bones in Niger in 1997. The species is named after French paleontologist Philippe Taquet, who worked earlier on Nigersaurus.
Nigersaurus -- so named because it was discovered in Niger -- had the long neck of a Diplodocus and up to 1,000 teeth in its intricate jaws, Sereno, of the University of Chicago, said on Monday.
Snails have the most teeth of any animal
Snails teeth are not like regular teeth. A snail's teeth are arranged in rows on its tongue. A garden snail has about 14,000 teeth while other species can have over 20,000.
What Dinosaur Had the Largest Teeth? The legendary Tyrannosaurus rex holds the record for the longest tooth at 12 inches. T. rex had 50 to 60 thick, conical, and serrated teeth that were replaced after being broken.
Utahceratops and Kosmoceratops both belong to a group of big-bodied horned dinosaurs called ceratopsids, and are close relatives of the more well-known triceratops.
Unlike any other plant eater, Nigersaurus had more than 50 columns of teeth, all lined up tightly along the front edge of its squared-off jaw, forming, in effect, a foot-long pair of scissors.
Scientists believe the extinction was caused by an asteroid impact on the present-day Yucatan Peninsula in Mexico. Nigersaurus marked in red.
What dinosaur has 99999 teeth? Nigersaurus is a genus of rebbachisaurid sauropod dinosaur that lived during the middle Cretaceous period, about 115 to 105 million years ago. It was discovered in the Elrhaz Formation in an area called Gadoufaoua, in the Republic of Niger.
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 500 replaceable teeth.
The dinosaur with the longest name was Micropachycephalosaurus meaning "tiny thick-headed lizard". Its fossils have been found in China, and it was named in 1978 by the Chinese paleontologist Dong.
You might call allosaurus, a meat-eating dinosaur from the Jurassic Period, the ultimate big mouth. A new study analyzing dinosaur jaw musculature found that this fearsome hunter that prowled North America about 150 million years ago was able to crank open its jaws between 79 and 92 degrees, wider than a right angle.
Over time, the smaller teeth in the back move up, replacing the front ones. Most sharks have between 5-15 rows, and the whale shark has a whopping 3,000 teeth in its mouth! But because those teeth aren't attached to their gums on a root like ours, they lose around a tooth every week.
Mamenchisaurus sinocanadorum had the longest neck of any known dinosaur, researchers said.
It was about the size of a bee hummingbird, making it the smallest dinosaur discovered yet. The findings were published today in Nature. Close up of Oculudentavis in Amber, finger shown for scale. The new species is named Oculudentavis or "eye-tooth-bird” for its weird features—large eyes and lots of teeth.
Troodontids (formerly Saurornithoidids) were remarkable in having the largest brain-to-body size ratio of all non-avian dinosaurs, possibly making them the most intelligent dinosaurs on a level with the smartest birds.
The teeth of Indominus were from Deinosuchus DNA, explaining why the teeth are exposed like a crocodile. Due to this bit of instability, its teeth varied in size, often jutting out at unnatural angles and many were broken. Indominus rex had a total of 74 teeth.
Apart from the large frill, Torosaurus was similar in appearance to its close relative, Triceratops. Both ceratopsians had two long horns sprouting above the eyes with a smaller horn on the snout. Torosaurus used its sharp beak and rows of shearing teeth to munch tough vegetation.
Zuniceratops was relatively small, had only two brow horns, and doesn't look quite as imposing as its later Cretaceous relatives, but those characteristics are part of why this dinosaur is significant to paleontologists looking at the big picture of horned dinosaur evolution.
The triceratops was a dinosaur that looked a bit like a rhinoceros. It lived around 65 million years ago, during what is called Cretaceous Period.
Of all the bites in the animal world, the Tyrannosaurus rex's may be the most famously terrifying. Now, it's also the strongest known to science, according to new research.
African Elephant: Their regal tusks are actually enlarged incisors, almost a third of which are embedded in their skulls. They grow on average about 6 feet long and weigh about 100 pounds each. The longest elephant tusk recorded was a whopping 11.5 feet, and the heaviest was about 250 pounds.
