In Depth

       Nyasasaurus made headlines all around the world when it was discovered,‭ ‬because this genus might just represent the oldest dinosaur so far discovered.‭ ‬Nyasasaurus has the right number of sacral vertebrae expected,‭ ‬and the humerus does display rapid growth patterns just like those known from other dinosaur genera.‭ ‬Unfortunately,‭ ‬the overall incompleteness of the Nyasasaurus‭ ‬holotype means that it is impossible to be certain if it actually is a dinosaur.‭ ‬If not,‭ ‬then Nyasasaurus would still be a reptile that came very close to actually being one.‭ ‬Future discoveries will likely shed more light upon exactly when and how dinosaurs finally split from their archosaur ancestors.
