The authors therefore cautioned versus working with semicircular canals as proxy to infer the precise orientation of skulls. They found that diet plan correlated strongly with semicircular canal orientation, although not with head posture, although head posture and semicircular canal orientation had been strongly correlated with phylogeny.[25]
In Nigersaurus' circumstance, the upper jaws contained sixty columns of little, needle-shaped higher teeth. And no less than 68 very sharp teeth had been present over the reduced jaws. Tallied collectively, upper jaw and decrease jaw, the beast experienced in excess of five hundred unique teeth.
In 1997, when paleontologist Paul Sereno 1st began to unearth the continues to be of a dinosaur in Niger's Sahara Desert, he didn’t know what to Believe. He was excavating bones in the dry area known as Gadoufaoua, which experienced a abundant fossil bed initial found by French uranium miners.
The Nigersaurus, with its five hundred teeth, showcases the marvels of evolution. Its specialized dental anatomy, tailored to its ecosystem and diet regime, serves as being a testament towards the adaptability and diversity of prehistoric life.

Nigersaurus's downward-dealing with mouth and vast dental arrangement advise it grazed on ground-stage plants rather than browsing substantial vegetation.
Nigersaurus is best noted for its unique skull and jaw, which contained somewhere around 500 slender teeth organized in tightly packed rows. These teeth have been specialized for grazing on small-lying vegetation, generating Nigersaurus a highly economical herbivore.
[13] Due to the lateral orientation of the teeth, it almost certainly wouldn't happen to be in the position to chew.[one] Nigersaurus wore its tooth crowns down what dinosaur has 500 teeth faster than other dinosaurian herbivores,[3] and its tooth substitute charge was the highest of any recognized dinosaur. Each and every tooth was replaced at the time each individual 14 days; the speed experienced Beforehand been believed reduced. In contrast to Nigersaurus, sauropods with reduced tooth substitute fees and broader tooth crowns are assumed to are actually Cover browsers.[12]
This Nigersaurus was a hatchling, possibly under a single year from hatching when it died and was fossilized.
Dinosaur-hunters are used to discovering dental batteries in beaked herbivores such as the horned Triceratops and shovel-billed Edmontosaurus. Nevertheless they're rare among the sauropods.
The sauropod dinosaur Nigersaurus very likely advanced its surprisingly-formed head to higher mow prehistoric lawns.
