mod that only adds a prehistoric and or a future era's to the game?

is there a mod that only adds a prehistoric and or a future era's to the game?

I quess i could put up with some graphical changes as well, units-terrian

but what I don't need is 5000million other changes

I am mostly only interested in extended eras

I have tryed the prehistoric mod, but it ctd's without starting and some of the othermodpacks add the eras I want but also add a bunch of junk I don't

No I don't expect modders to tailor there work to my needs, was just hoping ther was something out there I have over looked

thanks in advance for any answers comments suggestions
