“It’s a thing that truly takes the cake for remarkable cranial adaptations During this group, the lengthy-necked dinosaurs,” states Sereno, a professor of paleontology with the College of Chicago. “It’s simply a majestic illustration of evolution.”
Given that many rebbachisaurids inhabited latitudes that may are already tropical to subtropical in the Middle Cretaceous, this pneumaticity can have assisted the animals cope Along with the very substantial temperatures. Based on Ibiricu and colleagues, this adaptation could be a motive why rebbachisaurids had been the one team of diplodocoids that survived in the Late Cretaceous.[21]
But a third sauropod, the South American Antarctosaurus, may or may not are already a kissing cousin as well.
Nigersaurus, a rebbachisaurid sauropod from the center Cretaceous period of time, was identified inside the Elrhaz Development in Niger. Its name, which implies “Niger’s lizard,” was given pursuing the discovery of extra entire remains in 1999, although its fossils have been initial explained in 1976.
We've been closing in on that target quickly since we came upon a skeleton a few days afterwards! This skeleton is lying on its aspect With all the tail curved upward. The curve of the backbone actions about fifteen ft.
Its exclusive dental structure suggests that it could have had a distinct feeding technique when compared with other sauropods, and its existence in Africa suggests that these kinds of dinosaurs were much more common than Beforehand considered.
French paleontologists located the main fossils of Nigersaurus in the Nigerian Sahara in the nineteen fifties. On the other hand, considering that many of the bones have been both isolated or incomplete (due to their fragility), it was not possible to detect the species.
Nigersaurus (/niːˈʒɛərsɔːrəs, ˈnaɪdʒərsɔːrəs/) is a genus of rebbachisaurid sauropod dinosaur that lived throughout the center Cretaceous period of time, about 115 to a hundred and five million many years ago. It had been found out inside the Elrhaz Development in an area named Gadoufaoua, in Niger.
In 2019, Mannion and colleagues pointed out that considering that Nigersaurus was observed for being the sister taxon of all other nigersaurines in certain studies, a Rebbachisaurinae clade might not necessarily involve Nigersaurus by itself (together with the undeniable fact that the place of Rebbachisaurus could transform in potential analyses), and supported the continued use in the name Nigersaurinae about Rebbachisaurinae for all rebbachisaurids a lot more intently relevant to Nigersaurus than to Limaysaurus.

But that’s not all for Nigersaurus. Chris took us all to some flat spot of purple-coloured sandstone wherever he experienced Found the upper jaw of the baby Nigersaurus—one particular that will in good shape on top of a silver dollar!
Horsetails (Equisetum) Use Nigersaurus a central, hollow stem with whorls of leaves or slim branches. They keep their spores inside of a cigar-shaped “cone” at the top of the plant. Horsetails day back again to ~370 million a long time ago. During the beginning on the dinosaur era they grew to become almost thirty ft tall (10m.)
The dinosaur's vertebrae was filled with air pockets just like those of birds, Therefore the dinosaur was probably fairly mild, at the same time. Its Mind was regarding the size of the walnut, which can be kind of common for sauropods, Sereno suggests.
This intriguing variation showcases the varied tactics dinosaurs made to prosper in their environments. The Nigersaurus’s speedy tooth alternative, transpiring each fourteen days, is additionally amazing, location it other than other sauropods that had slower tooth turnover.
