The key lies within the creature’s bones. Researchers might need found a lot more Nigersaurus fossils If your animal experienced not experienced such a delicate bone structure. In accordance with a research by Sereno et al. 2007, this creature had an very lightweight cranium. Most of the bones in Nigersaurus
It even more argued the orientation of your semicircular canals varies substantially within just fashionable species, and is particularly therefore not reliable for analyzing head posture.[23] This was supported through the Spanish palaeontologist Jesús Marugán-Lobón and colleagues inside of a 2013 study that instructed the approaches utilized by Sereno's crew ended up imprecise, and that Nigersaurus habitually held its head like other sauropods.[24]

Nigersaurus most likely utilized its dental batteries to successfully course of action lower-lying vegetation like ferns and horsetails, which it gathered with its vast muzzle. It most likely fed at ground amount due to its quick neck, and its teeth would've worn out promptly from shearing by way of challenging vegetation.
There has been discussion on no matter whether its head was habitually held downwards, or horizontally like other sauropods. It lived within a riparian habitat, and its food plan in all probability consisted of sentimental crops, including ferns, horsetails, and angiosperms. It is one of the most typical fossil vertebrates found in the region, and shared its habitat with other dinosaurian megaherbivores, as well as substantial theropods and crocodylomorphs.
Immediately after conducting a biomechanical Examination, one particular workforce of researchers concluded that The pinnacle and muzzle ended up habitually oriented sixty seven° downwards and close to the bottom as a consequence of adaptation for ground-level browsing.
The swift substitution of its teeth, each individual fourteen times, implies the Nigersaurus faced considerable evolutionary pressures to keep up a continuing provide of functional teeth to manage with abrasive plant product. This adaptation underlines the evolutionary imperative to improve feeding efficiency in an ecosystem exactly where food items resources diversified and Competitiveness was intense.
This quick tooth substitute, with new teeth developing just about every fourteen days, ensured it taken care of sharp edges for grazing on delicate vegetation. The distinctive dental arrangement manufactured it hugely successful at processing lower-lying vegetation, contributing to its reputation to be a specialised herbivore.
Placing alongside one another these odd anatomical particulars, Nigersaurus seems to are already nicely tailored to very low searching; most likely it swept its neck back and forth parallel to the ground, hoovering up any vegetation inside straightforward get to. (Other sauropods, which experienced for much longer necks, may perhaps have nibbled over the superior branches of trees, nevertheless even this remains a make a difference of some dispute.)
The jaws could have borne a keratinous sheath. As opposed to other tetrapods, the tooth-bearing bones of its jaws were rotated transversely relative to the rest of the cranium, so that every one of its teeth have been Situated considerably to your front. Its skeleton was highly pneumatised (stuffed with air Areas connected to air sacs), though the limbs ended up robustly built.
The name "Nigersaurus" has begun controversy and discussion while in the scientific Neighborhood and beyond due to its likely for misinterpretation and unintended connotations.
This Nigersaurus was a hatchling, likely a lot less than one particular yr from hatching when it died and was fossilized.
Dental batteries are a singular adaptation located in some plant-taking in dinosaurs that allowed them to competently approach difficult vegetation. These batteries encompass vertically stacked columns of teeth, what dinosaur has 500 teeth with the major tooth in Every single column becoming changed because it wears out.
Nigersaurus was almost certainly a browser, and fed with its head near the ground. The location of its brain that detected scent was small, While its brain dimensions was comparable to that of other dinosaurs. There's been discussion on regardless of whether its head was habitually held downwards, or horizontally like other sauropods.
