Nigersaurus had a exceptional dental battery consisting of about five hundred slender, carefully packed teeth, organized in rows along its vast, flat jaw.
Nigersaurus didn't show the identical modifications witnessed while in the jaws of other dinosaurs with dental batteries, or mammals with elaborate chewing features. The decreased jaw was L-shaped and divided in the subcylindrical transverse ramus, which contained the teeth, and the back ramus, which was a lot more lightweight and was The placement for many of the muscle mass attachments. It absolutely was unique in the tooth row expanded to the sides in the plane of the most crucial ramus with the reduce jaw.
Only by bringing with each other plants from within the globe and several different modern-day environments can a dinosaur-age scene be recreated. A few of the vegetation, like ginkgos, glimpse just about the same as their extinct ancestors; some, much like the conifer Araucaria, had been the dominant trees on the forests a hundred and ten million many years in the past.
Nigersaurus, a rebbachisaurid sauropod from the middle Cretaceous period, was discovered in the Elrhaz Development in Niger. Its title, which implies “Niger’s lizard,” was supplied following the invention of far more entire continues to be in 1999, Whilst its fossils had been initially explained in 1976.
We're closing in on that aim fast because we arrived on a skeleton a couple of days afterwards! This skeleton is lying on its aspect Along with the tail curved upward. The curve on the backbone steps about 15 toes.
These teeth and the shape in the sauropod's cranium possible evolved that will help it munch on plants very low to the bottom. Grass wasn’t about nonetheless throughout its time, but Nigersaurus possibly spent Significantly of its time grazing on a thing like it, wearing down its teeth in no time.
The Nigersaurus, with its 500 teeth, showcases the marvels of evolution. Its specialised dental anatomy, tailor-made to its ecosystem and diet regime, serves as being a testament for the adaptability and diversity of prehistoric lifestyle.
Nigersaurus what dinosaur has 500 teeth is thought from various partial skeletons and isolated bones, which have delivered precious details about its anatomy and actions.
The lizard from Niger was a relatively modest sauropod, measuring all-around nine meters (30 ft) in duration and weighing about 4 tons. It had a protracted neck and tail, with a brief, slender snout which was adapted for browsing on very low-lying vegetation.
The jaws may have borne a keratinous sheath. Contrary to other tetrapods, the tooth-bearing bones of its jaws were rotated transversely relative to the remainder of the cranium, so that each one of its teeth were being Positioned far into the front. Its skeleton was extremely pneumatised (full of air spaces linked to air sacs), nevertheless the limbs had been robustly crafted.
Teeth at different progress phases, Museo di Storia Naturale di Venezia The slender teeth had slightly curved tooth crowns, which were oval in cross-portion. The crowns have been unique in acquiring distinguished ridges on the margins of their midline and sides. The teeth in the lessen jaw may possibly happen to be twenty–thirty% smaller sized than Those people inside the upper jaw, but couple are identified, and they're of unsure maturity. In addition to this, the teeth ended up equivalent.[4] Below Each individual active tooth there was a column of nine substitution teeth inside the jaw.
Feeding on like which can be rough on the dental wellbeing Until you do have a syteady supply of substitution teeth. Nigersaurus need to have worn out its tooth crowns at a fast-fireplace speed.
Dental batteries are a unique adaptation located in some plant-taking in dinosaurs that allowed them to competently course of action challenging vegetation. These batteries consist of vertically stacked columns of teeth, While using the prime tooth in Every column being changed because it wears out.
This intriguing variation showcases the numerous techniques dinosaurs developed to thrive within their environments. The Nigersaurus’s rapid tooth alternative, occurring each fourteen times, is also impressive, location it aside from other sauropods that experienced slower tooth turnover.
