The trick lies from the creature’s bones. Scientists might have identified far more Nigersaurus fossils In the event the animal had not experienced these kinds of a fragile bone composition.

French paleontologists uncovered the main fossils of Nigersaurus inside the Nigerian Sahara in the 1950s. Having said that, since a lot of the bones have been either isolated or incomplete (because of their fragility), it had been extremely hard to establish the species.
This quick tooth alternative, with new teeth rising every fourteen times, ensured it maintained sharp edges for grazing on tender vegetation. The one of a kind dental arrangement made it very economical at processing small-lying crops, contributing to its popularity to be a specialised herbivore.
