The adductor muscle mass of your jaw appears to get connected towards the quadrate rather than the supratemporal fenestra. Both this and the other mastication muscles were being probable weak, and Nigersaurus is estimated to own had on the list of weakest bites of your sauropods.[3] In addition, In keeping with Whitlock and colleagues in 2011, the compact, virtually parallel nature of the tooth scratches and pits (because of grit, which might not be attained as normally by significant-browsers) reveal that it ate reasonably gentle, herbaceous crops for instance lower-growing ferns.
The nickname "dinosaur with five hundred teeth" originates from Nigersaurus's exclusive dental battery. Its jaw held roughly five hundred slender teeth, arranged in tightly packed rows, and these teeth were being constantly changed through its daily life.
Only by bringing collectively plants from throughout the world and many different fashionable environments can a dinosaur-age scene be recreated. A number of the vegetation, like ginkgos, look almost the same as their extinct ancestors; some, much like the conifer Araucaria, were being the dominant trees in the forests a hundred and ten million years in the past.
Nigersaurus also bears signs of reduced-angle tooth-to-tooth don on the inside with the maxillary crowns, which suggests that jaw movement was restricted to exact up-and-down motions. Worn teeth with the lower jaw have not but been identified, but They are really anticipated to indicate opposing tooth-to-tooth don. The opportunity to elevate their heads well earlier mentioned the bottom would not necessarily imply they browsed on goods there, and the brief neck of Nigersaurus might have restricted the searching vary in comparison with other diplodocoids.[3]
e. Apatosaurus. They also experienced predators that lived in the identical location and one in their predators was theropoda.
Fossil evidence implies it lived in what is currently the Sahara Desert, feeding on ferns and various vegetation in its lush, riverine habitat.
The rapid substitute of its teeth, every fourteen days, implies the Nigersaurus faced substantial evolutionary pressures to keep up a relentless supply of practical teeth to cope with abrasive plant content. This adaptation underlines the evolutionary vital to improve feeding effectiveness in an setting the place meals resources diversified and competition was intense.
Wedel and said in 2016 that though sauropods usually could use their what dinosaur has 500 teeth prolonged necks to detect predators from afar, This might not apply into the small-necked Nigersaurus. They pointed out which the eyes of Nigersaurus ended up placed further toward the very best of your cranium than in many other sauropods, higher than the muzzle, which might give it overlapping fields of see. Its Visible area would have been at or near to 360 degrees, and hypersensitivity of motion might have been important to a vulnerable prey-animal.[20]
A 2009 examine with the British palaeontologist Mike P. Taylor and colleagues agreed that Nigersaurus was capable to feed Together with the downturned head and neck posture proposed with the 2007 examine, but contested that this was the habitual posture of the animal. The study pointed out which the "neutral" head and neck posture of recent animals isn't going to always correspond to their habitual head posture.
Fossils of this dinosaur ended up to start with described in 1976, but it was only named Nigersaurus taqueti in 1999, right after further plus much more full stays ended up observed and explained. The genus identify implies "Niger reptile", and the precise identify honours the palaeontologist Philippe Taquet, who uncovered the initial stays.
This weird, long-necked dinosaur is characterised by its unusually broad, straight-edged muzzle tipped with in excess of 500 replaceable teeth. The initial fossil skull of Nigersaurus has become the initial dinosaur skulls being digitally reconstructed from CT scans.

Skeletal diagram exhibiting regarded elements and measurement comparison Sereno along with the American palaeontologist Jeffrey A. Wilson furnished the first thorough description in the cranium and feeding adaptations in 2005.[one] In 2007, a far more specific description of your skeleton was published by Sereno advertisement colleagues, determined by a specimen learned 10 years previously. The fossils, along with a reconstructed skeleton mount plus a plastic product of The pinnacle and neck, have been subsequently offered with the National Geographic Society in Washington.
This intriguing variation showcases the numerous tactics dinosaurs created to prosper of their environments. The Nigersaurus’s speedy tooth substitution, happening every 14 times, is additionally amazing, setting it other than other sauropods that experienced slower tooth turnover.
