Even the skies had been occupied – prolonged-winged flying pterosaurs swooped overhead, from time to time diving down to grab a delicious fish out of the river.
Nevertheless it had huge nostrils plus a fleshy snout, Sereno and colleagues located that Nigersaurus experienced an underdeveloped olfactory area of its Mind and thus did not have a complicated sense of smell. Its Mind-to-physique-mass ratio was normal for just a reptile, and smaller than People of ornithischians and non-coelurosaurian theropods. The cerebrum comprised about thirty% in the Mind quantity, as in many other dinosaurs.[3] The American palaeoartist Mark Hallett and paleontologist Mathew J.
Beyond its paleontological significance, Nigersaurus has received consideration on the net on account of its name. Some Net memes, especially the "Never Google" craze, have highlighted the dinosaur as "the a person with 500 teeth.
Nigersaurus likely utilised its dental batteries to successfully course of action very low-lying vegetation like ferns and horsetails, which it collected with its wide muzzle. It most likely fed at ground stage resulting from its shorter neck, and its teeth might have worn out rapidly from shearing by means of rough vegetation.
Nigersaurus is believed to behave much like other herbivore sauropods. That they had probably expended most of their time in cling-Pet positions and grazing lower-lying vegetation.
Fossil evidence suggests it lived in what has become the Sahara Desert, feeding on ferns and also other vegetation in its lush, riverine habitat.
in 1999, after additional and even more finish continues to be were observed and explained. The genus identify usually means "Niger reptile", and the specific name honours the French palaeontologist Philippe Taquet, who discovered the initial continues to be.
On the basis of microtomography scans of skull aspects of your holotype specimen, Sereno and colleagues produced a "prototype" Nigersaurus skull they might take a look at. They also produced an endocast on the brain and scanned the semicircular canals of its internal ear, which they uncovered to become oriented horizontally. Inside their 2007 research, they said which the structure in the occiput behind the cranium 500 teeth dinosaur and cervical vertebrae would've limited the upward and downward motion in the neck plus the rotation of your skull.
Paleontologist Paul Sereno described Nigersaurus as “the weirdest dinosaur I’ve ever seen” in the event the dinosaur’s strange characteristics were initially identified in 2007. The teeth were specially noteworthy simply because they were organized in dental batteries, which are generally present in beaked herbivores like Triceratops and Edmontosaurus, but are rare between sauropods.

A 2023 examine by the French palaeontologist Rémi Lefebvre and colleagues examined the microanatomical framework of the limb bones of Nigersaurus by means of CT-scans, the very first this sort of study of a sauropod. Digital sections of the limb bones sampled from men and women of various dimensions ended up explored to ascertain the variety of variation. Heavy-weight bearing animals often have features connected with this condition, influencing the interior construction in the limb bones, although the variation involving these bones is improperly recognised.
Horsetails (Equisetum) have a central, hollow stem with whorls of leaves or slender branches. They keep their spores inside a cigar-shaped “cone” at the top of your plant. Horsetails date back again to ~370 million a long time ago. During the start from the dinosaur era they grew being just about 30 feet tall (10m.)
This structure was among the very first dinosaur skulls to become digitally reconstructed making use of CT scans, presenting unparalleled insights into its feeding mechanics.
This reptile was significantly greater than any dwelling crocodile. Judging through the 6-foot skull we present in the very first 7 days, we suspect it might have measured above forty feet very long! The armor plates on its back calculated a foot throughout. We even laid out the team to secure a feeling of just how large this animal was.
