What dinosaur has 99999 teeth?
Hadrosaurs, or duck-billed dinosaurs, had the most teeth: up to 960 cheek teeth!
More surprising was the number of enamel-covered teeth, 1,000 of them, that Nigersaurus would use to eat its vegetarian diet. The tiny teeth are in "batteries", side by side, like soldiers on parade.
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.
One, Kosmoceratops richardsoni, had 15 horns on its head, while the other, Utahceratops gettyi, had five.
The longest dinosaur tooth ever recorded belonged to a T. Rex, and they were a whopping 12 inches long! This measurement includes the tooth's root though, so the exposed part of the tooth was 6 inches long.
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.
When the researchers who found Berthasaura leopoldinae realized the dinosaur in front of them had no teeth, they immediately thought of Limusaurus inextricabilis, a toothless theropod discovered in northwestern China. Limusaurus lived sometime between 161 million and 156 million years ago, during the Jurassic period.
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.
Its shovel-shaped jaws and tightly packed teeth -- up to 10 rows of teeth -- allowed Nigersaurus taqueti to vacuum through ferns and other ground cover, a team led by Paul Sereno at the University of Chicago reported.
Nigersaurus had so many teeth it has been dubbed "the mesozoic lawnmower," but while it may may have looked like "a hammerhead shark with legs," even it had a match.
Mamenchisaurus sinocanadorum had the longest neck of any known dinosaur, researchers said.
The first bones of Nigersaurus were picked up in the 1950s by French paleontologists, though the species was not named. Sereno and his team honored this early work by naming the species after French paleontologist Philippe Taquet.
Dinosaurs were able to continuously grow teeth throughout their lives. When a tooth was broken, another could replace it. “It could take up to two years for a tooth to grow back in the big theropods like T. rex.
The tiniest teeth likely belong to the needle-like teeth of the paravian dinosaurs like Microraptor. Many theropods lose teeth while digging into their meals and they've occasionally been found embedded in the fossilized remains of their prey.
The enormous dinosaur, which was 42 feet long and weighed 19,400 pounds, roamed prehistoric Saskatchewan 66 million years ago. A high school teacher and palaeontologists with the Royal Saskatchewan Museum who were out prospecting for fossils found Scotty in the badlands just outside of East End in 1991.
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.
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.
Unlike its better-known cousin Triceratops, Pachyrhinosaurus had no horns on its face. The lumpy mass of bone, called a nasal boss, was likely used for combat with its own species.
Leech: The interior structure of a leech is divided into 32 different segments, each of which has its own brain.
Snails have more teeth than any animal.
This is TRUE. A snail's mouth is no larger than the head of a pin, but can have over 25,000 teeth (but these aren't like regular teeth, they are on its tongue).
Centipede. Centipedes are long, thin arthropods with one pair of legs per body segment. Despite "centi" in their name, which implies 100 legs, centipedes can have fewer than 20 legs to more than 300 legs, but they always have an odd number of pairs of legs.
