Nigersaurus had a outstanding dental battery consisting of roughly 500 slender, intently packed teeth, organized in rows alongside its vast, flat jaw.

Given that numerous rebbachisaurids inhabited latitudes that may happen to be tropical to subtropical in the Middle Cretaceous, this pneumaticity could possibly have helped the animals cope Together with the extremely substantial temperatures. In keeping with Ibiricu and colleagues, this adaptation could be a cause why rebbachisaurids had been the only real group of diplodocoids that survived in the Late Cretaceous.[21]

Nigersaurus is assumed to own lived in huge herds and may have migrated around prolonged distances searching for food stuff.

The continues to be of Nigersaurus ended up in the beginning explained by Taquet in 1976 as belonging to the dicraeosaurid, but in 1999 Sereno and colleagues reclassified it as a rebbachisaurid diplodocoid.[four] These scientists speculated that since small necks and small dimension was identified amid basal diplodocoids, it could indicate these have been ancestral capabilities in the group.

On The idea of microtomography scans of skull elements of your holotype specimen, Sereno and colleagues created a "prototype" Nigersaurus cranium they may analyze. Additionally they manufactured an endocast in the brain and scanned the semicircular canals of its inner ear, which they located to get oriented horizontally. Within their 2007 examine, they said the construction from the occiput at the back of the skull and cervical vertebrae would have limited the upward and downward movement of your neck plus the rotation with the skull.

 lived in what has become Niger about 115 to a hundred and five million many years in the past, during the Aptian and Albian ages on the mid-Cretaceous. It likely lived in habitats dominated by inland floodplains (a riparian zone).

With the astonishing five hundred teeth, this dinosaur gives a unique glimpse into the evolutionary adaptations of prehistoric creatures. Permit’s investigate the whole world on the Nigersaurus and its interesting dental anatomy.

Nigersaurus are famous dinosaurs for possessing five hundred slender teeth within their jaw. These dinosaurs are regarded not long ago in the year 2000 and had been named in the dignity of country “Niger”. The term Nigersaurus has two areas; Niger (place title), and Saurus (reptile).

On the other hand, as mentioned, Nigersaurus had a continuing supply of recent teeth since they were changed once the top rated tooth in the column wore out.

Among the myriad of dinosaurs that after roamed our World, the Nigersaurus stands out, not for its size or ferocity, but for its extraordinary dental structure.

It was a quadrupedal dinosaur, this means that it walked on all fours. Having said that, its legs had been rather shorter compared to its human body. It is assumed to have already been proficient at rearing up on its hind legs to be able to arrive at bigger amounts of vegetation.

Horsetails (Equisetum) Possess a central, hollow stem with whorls of leaves or slender branches. They hold their spores inside a cigar-shaped “cone” at the top on the plant. Horsetails day back to ~370 million yrs in the past. In the course of the beginning from the dinosaur era they grew to be practically 30 toes tall (10m.)

Things obtained more interesting in 1997. Which is each time a member of Sereno's field crew found some Nigersaurus skull bones. In excess of the program of two expeditions, plenty what dinosaur has 500 teeth of materials was identified to reconstruct about eighty percent in the beast's skeleton.

The Nigersaurus was a ground-amount browser. Its vast muzzle, combined with its a lot of teeth, permitted it to soak up huge amounts of vegetation in one Chunk. The orientation of its teeth, all positioned within the entrance of its jaws, enabled it to successfully crop and Assemble food items close to the bottom.
