Nigersaurus experienced more than 500 teeth arranged in dental batteries (rows of teeth stacked on other rows of teeth), which allowed it to competently graze on minimal-lying vegetation like ferns and horsetails. Worn Nigersaurus teeth ended up continually replaced to keep up Niversaurus' productive feeding.
A 2023 analyze via the French palaeontologist Rémi Lefebvre and colleagues examined the microanatomical composition on the limb bones of Nigersaurus by CT-scans, the primary such examine of a sauropod. Digital sections of the limb bones sampled from folks of different measurements ended up explored to ascertain the selection of variation. Large-fat bearing animals normally have attributes linked to this issue, influencing the interior framework of your limb bones, however the variation among these bones is improperly recognised.
