He identified several fossils from Elrhaz formations in Niger. Amongst People fossils, he observed fossils of a different dinosaur species that is referred to as Nigersaurus (“Niger Reptile”). He together with other paleontologists gathered many bony portions of Nigersaurus separately and assembled a tough skeleton.
Nigersaurus (/niːˈʒɛərsɔːrəs, ˈnaɪdʒərsɔːrəs/) is usually a genus of rebbachisaurid sauropod dinosaur that lived for the duration of the middle Cretaceous interval, about one hundred fifteen to 105 million decades back. It absolutely was uncovered while in the Elrhaz Formation in a location known as Gadoufaoua, in Niger.
Many of the tooth columns in Nigersaurus' dental batteries ended up lined up, not like the teeth of other dinosaurs, on the extremely entrance of its mouth, positioned alongside the muzzle's gently curved periphery.
A 2009 study by the British palaeontologist Mike P. Taylor and colleagues agreed that Nigersaurus was able to feed While using the downturned head and neck posture proposed by the 2007 analyze, but contested that this was the habitual posture in the animal. The research noted which the "neutral" head and neck posture of contemporary animals will not essentially correspond for their habitual head posture.
This Nigersaurus was a hatchling, likely below just one calendar year from hatching when it died and was fossilized.”
Teeth at distinctive expansion phases, Museo di Storia Naturale di Venezia The slender teeth experienced marginally curved tooth crowns, which were oval in cross-area. The crowns ended up distinct in acquiring well known ridges over the margins of their midline and sides. The teeth while in the lower jaw may possibly happen to be 20–30% scaled-down than Individuals what dinosaur has 500 teeth in the upper jaw, but several are recognized, and they are of unsure maturity. Other than this, the teeth were similar.[four] Less than Each individual active tooth there was a column of nine substitution teeth inside the jaw.
Nigersaurus's feeding approach was contrary to many other dinosaurs. Its broad, flat jaw was adapted for grazing near to the ground, earning it the nickname "Mesozoic Cow."
These teeth ended up also replaceable (like sharks’ teeth), indicating Nigersaurus constantly essential clean teeth as more mature ones ended up worn down or missing.
While walking throughout an exceedingly flat region, Gabe built a impressive find—the bones of a different meat-feeding on dinosaur lay partially exposed at her toes. She brushed absent the sand from the upper jaw.
The skull of the Nigersaurus was manufactured from skinny bones and had numerous modest openings and pores. These functions delivered them fantastic adaptability in feeding on the ground. The muzzle of the Nigersaurus was wide and long which assisted it in taking in smaller ground-based mostly vegetation.
The Nigersaurus is an interesting and distinctive dinosaur which has captured common attention, partly as a result of its unconventional characteristics and intriguing nickname given that the "dinosaur with 500 teeth."
It experienced a wide muzzle stuffed with in excess of 500 teeth, which were being replaced in a immediate rate: close to each and every 14 days. The jaws could have borne a keratinous sheath. As opposed to other tetrapods, the tooth-bearing bones of its jaws were being rotated transversely relative to the rest of the skull, so that all of its teeth ended up Positioned significantly to the entrance.
We are not speaking about AA Duracells here. Dental batteries had been economical food stuff processing applications employed by a lot of plant-eating dinos.
This revelation arises from The truth that, despite its elongated nostrils, the olfactory (smelling) area of its brain was relatively smaller for its dimension. 11. Nigersaurus could probably see just about 360 degrees although feeding
