After Cretaceous is a project about a paralel universe that diverges from ours, 66 million years ago. The difference is that the K-Pg extinction event didn't ocurred.

Periods Edit

After the Cretaceous period, 66 million years ago, new periods have arrived, each one with a name identic to those from our universe: Paleogene, Neogene and Quaternary. Paleogene (66-23 M.y.) makes the evolutionary transition from the classic Late Cretaceous animals to the new more radiated animals that were once less radiated. The Neogene (23-2 M.y.) shows a new line of evolution, in which animals have to withstand with a new range of climate and their taxonomical classification vs. geographical distribution vs. eccological niche diversity is way different from the Cretaceous period. The Quaternary (2-0 M.a.) is the only time period in which animals will be shown as distinct species. Every other periods will be mencioned with their respective animals, but they will only have a evolution-show role.

Creatures Edit

List of creature groups (NOTE: most groups here are speculative, not original)

(NOTE: You can find strong simillarities with modern animal groups. The fact is that they are replaced, in their eccological niches, by Mesozoic animals, despite some groups are living in our own universe)

(NOTE: It isn't finished, more groups could be added as I decide)

(NOTE: Contribution is welcome)

(NOTE: there are some prefixes that give us clues about the kind of creature the group descends)

(NOTE: These names should be changed in the future)
