Limb content and also a scapula uncovered close by were being also referred to exactly the same specimen. These fossils are housed on the Nationwide Museum of Niger.
Its head is what genuinely stands out about Nigersaurus, while. The jaws, that have a flat entrance, are lined with about five hundred teeth, which Sereno states were being replaceable. These teeth were all the identical in dimension, and he estimates they likely only lasted about a month or so prior to they had been worn down.
Preliminary discoveries of Nigersaurus fossils date back again towards the nineteen sixties, however it wasn't right until the 1970s that far more entire continues to be have been uncovered. These stays had been formally analyzed and explained by paleontologist Paul Sereno and his staff in 1999.
But that’s not all for Nigersaurus. Chris took us all to the flat place of purple-coloured sandstone where by he had Situated the higher jaw of a baby Nigersaurus—1 that might healthy in addition to a silver greenback!
On the basis of microtomography scans of cranium things with the holotype specimen, Sereno and colleagues developed a "prototype" Nigersaurus cranium they might look at. They also made an endocast on the Mind and scanned the semicircular canals of its internal ear, which they identified to become oriented horizontally. In their 2007 review, they mentioned that the construction from the occiput at the back of the cranium and cervical vertebrae would have confined the upward and downward motion from the neck and also the rotation of the cranium.

What's a lot more, the same as grazing cows these days, these creatures were ample through their heyday. After the initial discovery, Sereno found A different Nigersaurus specimen through an expedition in 2000.
Hans continues to be dealing with a crew of Allison and Dave to excavate a new internet site. As we dug around the skull, we uncovered A further juvenile skull of the identical species lying correct close to the massive 1.
When walking across an incredibly flat region, Gabe designed a remarkable uncover—the bones of a fresh meat-having dinosaur lay partially exposed at her feet. She brushed away the sand within the upper jaw.
The reconstructed skeleton of a very Strange dinosaur, the plant-consuming Nigersaurus. This can be a sculptural rendition of what the scientists hope the dinosaur's distinctive head might have looked like.
The most distinct features of Nigersaurus was its rows of small, peg-like teeth, which have been organized inside of a straight line along the front of its jaws. These teeth were being consistently replaced all over the dinosaur’s everyday living, letting it to feed constantly on difficult vegetation.
It experienced a wide muzzle stuffed with much more than 500 teeth, which have been replaced at a quick price: close to each individual fourteen days. The jaws could possibly have borne a keratinous sheath. In contrast to other tetrapods, the tooth-bearing bones of its jaws ended up rotated transversely relative to the remainder of the cranium, so that all of its teeth have been located significantly to the front.
Nigersaurus is understood from quite a few partial skeletons and isolated 500 teeth dinosaur bones, that have presented useful details about its anatomy and actions.
The nickname "dinosaur with 500 teeth" emanates from Nigersaurus's exclusive dental battery. Its jaw held around 500 slender teeth, organized in tightly packed rows, and these teeth have been regularly replaced all over its everyday living.
