Happy #FossilFriday! Meet Nigersaurus, the crazy long neck #dinosaur with hundreds of little teeth in the weirdest mouth!
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.
Bizarre 500-toothed dinosaur
Nigersaurus, you might remember, we named for bones collected on the last expedition here three years ago. This sauropod (long-necked dinosaur) has an unusual skull containing as many as 500 slender teeth.

Its skull was very specialised for feeding, with large fenestrae and thin bones. It had a wide muzzle filled with more than 500 teeth, which were replaced at a rapid rate: around every 14 days. The jaws may have borne a keratinous sheath.
Spinosaurus was even larger than Tyrannosaurus rex and measured 45 feet (13.7 meters) long. The colossus had an unusual skull shape that made it look more like a toothy crocodile than a raptor, said Paul Sereno, professor of organismal biology and anatomy at The University of Chicago.
“These are really, really neat looking animals,” says James Cook University geologist Eric Roberts, who is helping reveal the secret lives of the 15-horned Kosmoceratops richardsoni and its larger mate Utahceratops gettyi.
The vaquita is the most endangered cetacean in the world. With as few as around 10 left, the species will become extinct without a fully enforced gillnet ban throughout their entire habitat.
Studies show that some corals can live for up to 5,000 years, making them the longest living animals on Earth. Some corals can live for up to 5,000 years, making them the longest living animals on Earth.
The tubeworm Escarpia laminata that lives in deep sea cold seeps regularly reaches the age of between 100 and 200 years, with some individuals determined to be more than 300 years old. Some may live for over 1000 years.
They are a group of reptiles that lived between 245 and 66 million years ago. Approximately 66-65 million years ago, the non-avian dinosaurs became extinct. The reasons for extinction are still debated. However, avian dinosaurs (also known as modern birds) are still alive.
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.
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.
Micropachycephalosaurus, is the longest generic name for a dinosaur with 23 letters and nine syllables. For such a huge name, it was quite a small dinosaur as the name means `small thick-headed lizard'.
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.
Diplodocus would have had to eat all day to be able to survive on just leaves. Dinosaurs like Dippy had 42 teeth but over their lifetime they would have grown many more, as it's been estimated they replaced each tooth every 35 days.
Anything that tries to kill a tardigrade will quickly realize they encountered practically immortal animals. These creatures are capable of sticking around for thousands of years or even indefinitely “by entering a state of cryptobiosis, whereby their metabolism comes to a halt,” says Pastor.
What is the oldest cat to ever live? The oldest cat to ever live was Creme Puff, a Texas cat who lived to be 38 years old and 3 days.
Immortal jellyfish are biologically immortal and thus the oldest jellyfish ever. Though there is no official 'oldest jellyfish ever', there is a very special species of jellyfish that scientists say may be immortal – biologically at least.
There are only two northern white rhinos left in the world, both female. Yet there is still hope that we can preserve their lineage. Your support today could help offer a lifeline for the world's rarest mammal.
The single rarest animal in the world is the vaquita (Phocoena sinus).
Wild animals such as pandas and elephants are likely to become extinct as soon as 2025. Could you imagine by the time you may have started a family it is a possibility that your children will never see a panda or elephant?
This species is also one of the only horned carnivorous dinosaurs. The Carnotaurus lived in South America 69 to 71 million years ago in the Late Cretaceous period. As a theropod, the Carnotaurus walked upright on two legs but was not feathered.
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.
Carnotaurus is the only known carnivorous bipedal animal with a pair of horns on the frontal bone.
