Named following the state of Niger, the place its fossils had been initial located. The title was preferred to replicate its origins, having said that, the similarity in pronunciation to some racial slur has elevated concerns about cultural sensitivity and suitable terminology.

However, this claim continues to be contested by other researchers who believe that Nigersaurus was likely more common of other sauropods.
This quick tooth alternative, with new teeth rising each individual 14 days, ensured it taken care of sharp edges for grazing on delicate vegetation. The special dental arrangement manufactured it hugely economical at processing reduced-lying plants, contributing to its track record being a specialised herbivore.
Putting collectively these odd anatomical aspects, Nigersaurus seems to have already been very well tailored to very low searching; almost certainly it swept its neck back and forth parallel to the ground, hoovering up any vegetation inside straightforward access. (Other sauropods, which experienced much longer necks, might have nibbled within the substantial branches of trees, while even this continues to be a subject of some dispute.)
