Head's Up! (Possibly) For the reason that Nigersaurus ate with its head down, experts have puzzled about its posture. Sereno and his co-authors when argued that the herbivore aimed its confront and neck downwards — whether it was feeding or not — like a make a difference of routine.
Teeth at diverse growth levels, Museo di Storia Naturale di Venezia The slender teeth had somewhat curved tooth crowns, which have been oval in cross-segment. The crowns had been unique in having popular ridges around the margins of their midline and sides. The teeth from the lower jaw could have already been 20–30% more compact than Those people within the higher jaw, but number of are recognised, and they're of unsure maturity. Besides this, the teeth were being identical.[four] Less than Every single Lively tooth there was a column of 9 alternative teeth in the jaw.
This sauropod (extended-necked dinosaur) has an abnormal cranium that contains as a lot of as 500 slender teeth. A major target of this expedition is to discover the rest of this strange dinosaur so we can easily describe it and reconstruct it for everybody to find out.
Nigersaurus is a crucial discovery for paleontologists because it helps you to lose mild within the evolution and diversity of sauropods in the mid-Cretaceous period of time.

This Nigersaurus was a hatchling, almost certainly below a person 12 months from hatching when it died and was fossilized.
Though other heavy animals examined (like rhinoceroses) had thick and variable bone cortices, the cortex of Nigersaurus was relatively slim. These scientists prompt that the microanatomy of sauropods was not impacted by drastic selective strain due to bearing body weight, but that options such as the columnar limbs (as noticed in elephants), pneumaticity, and fleshy foot pads and cartilage calm strain about the bones. Additionally they instructed that sauropods may perhaps what dinosaur has 500 teeth therefore happen to be lighter in excess weight than anticipated for their dimensions, supporting the bottom system mass estimates for these dinosaurs.[22]
Issues got extra attention-grabbing in 1997. Which is each time a member of Sereno's area crew observed some Nigersaurus cranium bones. More than the course of two expeditions, adequate substance was identified to reconstruct about 80 p.c on the beast's skeleton.
Nigersaurus was named once the West African region exactly where its fossils ended up found out: the Republic of Niger. All through this creature’s time, the landscape (now Component of the Sahara Desert) is thought to are already lined with forests and braided rivers.
Its unique dental composition suggests that it could possibly have had a different feeding strategy as compared to other sauropods, and its existence in Africa implies that these sorts of dinosaurs ended up far more popular than Earlier considered.
Nigersaurus lived a hundred and ten million many years in the past in what has become Niger, West Africa. Although the fossils had been found in the Sahara Desert, when Nigersaurus lived the area was a floodplain with vast rivers, conifer forests and lush vegetation.
We've been closing in on that target rapidly simply because we came on a skeleton a few days afterwards! This skeleton is lying on its aspect Using the tail curved upward. The curve of your spine measures about fifteen ft.
This revelation comes from The point that, In spite of its elongated nostrils, the olfactory (smelling) location of its brain was somewhat little for its sizing. eleven. Nigersaurus could most likely see just about 360 degrees though feeding
