The adductor muscle of your jaw seems to get attached to your quadrate rather than the supratemporal fenestra. Both this and the opposite mastication muscles had been probable weak, and Nigersaurus is approximated to have experienced one of many weakest bites from the sauropods.[three] Furthermore, Based on Whitlock and colleagues in 2011, the compact, practically parallel nature of the tooth scratches and pits (a result of grit, which would not be received as frequently by higher-browsers) suggest that it ate rather smooth, herbaceous plants which include very low-developing ferns.
The nickname "dinosaur with 500 teeth" comes from Nigersaurus's distinct dental battery. Its jaw held about 500 slender teeth, arranged in tightly packed rows, and these teeth have been frequently replaced throughout its life.
The stays of Nigersaurus ended up originally described by Taquet in 1976 as belonging to a dicraeosaurid, but in 1999 Sereno and colleagues reclassified it like a rebbachisaurid diplodocoid.[4] These researchers speculated that because limited necks and tiny sizing was regarded amid basal diplodocoids, it might suggest these were ancestral functions with the group.
The authors as a result cautioned towards using semicircular canals as proxy to infer the specific orientation of skulls. They identified that diet plan correlated strongly with semicircular canal orientation, although not with head posture, when head posture and semicircular canal orientation have been strongly correlated with phylogeny.[25]
The Nigersaurus is an interesting and distinctive dinosaur that has captured common awareness, partly as a result of its uncommon characteristics and intriguing nickname since the "dinosaur with five hundred teeth."
The analyze of dinosaurs like Nigersaurus aids us to raised fully grasp the history of our World and also the vital part that these historical creatures played in shaping the earth as we know it currently.
As we’ve found, Nigersaurus had a wide muzzle and numerous teeth correctly suited to consuming reduced-lying plants. This diet program and Way of life might have essential the creature to have a constant source of alternative teeth, mainly because it would've worn out its tooth crowns promptly. A analyze posted in the journal PLOS A single

The Nigersaurus, with its extraordinary dental variety of five hundred slender teeth and also a wide, squared-off muzzle, serves for a amazing window into your evolutionary paths that dinosaurs took to adapt for their environments. This specialized feeder, in contrast to many of its sauropod relatives, progressed to snip and take in comfortable, 500 teeth dinosaur abundant vegetation close to the bottom, revealing a novel niche within the Cretaceous ecosystem.
The skull of a Nigersaurus was fabricated from thin bones and had many modest openings and pores. These characteristics offered them terrific versatility in feeding on the bottom. The muzzle from the Nigersaurus was wide and very long which assisted it in feeding on little floor-centered vegetation.
Teeth at different advancement stages, Museo di Storia Naturale di Venezia The slender teeth had a little bit curved tooth crowns, which have been oval in cross-section. The crowns were unique in having popular ridges on the margins of their midline and sides. The teeth from the reduce jaw may well happen to be twenty–thirty% scaled-down than These from the upper jaw, but several are recognized, and they are of unsure maturity. Other than this, the teeth had been similar.[4] Beneath each Energetic tooth there was a column of nine substitute teeth throughout the jaw.
The adductor muscle mass with the jaw seems to own attached into the quadrate instead of the supratemporal fenestra. The two this and one other mastication muscles were possible weak, and Nigersaurus is estimated to possess experienced among the list of weakest bites in the sauropods.[three] Additionally, In line with Whitlock and colleagues in 2011, the modest, virtually parallel character in the tooth scratches and pits (attributable to grit, which would not be received as usually by higher-browsers) reveal that it ate reasonably tender, herbaceous crops such as reduced-expanding ferns.
Nigersaurus didn't exhibit exactly the same modifications found during the jaws of other dinosaurs with dental batteries, or mammals with elaborate chewing capabilities. The decreased jaw was L-shaped and divided in the subcylindrical transverse ramus, which contained the teeth, and also the again ramus, which was extra light-weight and was The situation for the vast majority of muscle mass attachments. It absolutely was unique in which the tooth row expanded to the sides from your aircraft of the principle ramus with the lower jaw.
Its shorter neck would have also been an adaptation to this floor-degree feeding habits, as it wouldn't happen to be ready to succeed in high into trees like Various other sauropods.
