The history of Spec as a timeline distinct from that of Arel begins roughly 65 million years ago. On Arel, this point in time corresponds with the end of the Mesozoic Era and the dawn of the Cenozoic - the so called Cretaceous-Tertiary (K-T) boundary, although many workers now prefer to divide the Tertiary into the Paleogene(Paleocene-Oligocene) and Neogene(everything else).
