    The mere suggestion of a possible linked lineage between the feather-laden creatures we know today as birds and the extinct, reptilian dinosaurs would have once been deemed entirely ludicrous; however, arguably the most important paleontological finding in establishing this very notion occurred in the late 19th century with the discovery of the first Archaeopteryx lithographica fossil – dubbed the oldest bird.
