Ok before you start saying. Mario has no timeline its the same story. Well. This is for fun
Let's start.
1st.Super Mario World 2-Well mario is a baby. How far back can you go 
2nd Donkey Kong- This was before mario became a plumber and stumble into the Mushroom Kingdom.
3rd- Donkey Kong J.R- This has the story that it happens after Donkey Kong
4th Mario Bros- Mario becomes a plumber!
How mario got to to the Mushroom Kingdom is explained in the T.V show.
^ok those where obvious. Now let's do the hard ones.
5th Super mario bros- Well this one has only Bowser. Also a limited army. Has to be fifth
6th Super Mario Sunshine- Well This Game reveils Bowser's son.
7th Super Mario Galaxy- Bowser jr is here but not the koopa kids. Also the koopas re walking on 4 legs. Which mean they haven't learned
to walk on 2 yet 
8th Super Mario Bros 3- This has the Koopa kids not J.R though this has airships. So my guess is hat this doesn't take long after Galaxy.
9th Mario 64- Yeah. The koopas walk on 2 legs. Bypass evloution. So it has to take time after Mario 3
10th New Super Mario Bros DS- Bowser jr learns how to steal peach
. Koopas also walk on 2 legs here too.
11th Super Mario World- Yoshi is here for the first time since Mario world 2!<---That is confusing(koopas walk on 2 legs
)
12th and beyond- Mario sports Spin offs- Sometime in the distant future. All the charecters learn to play with each other 
Notes:
Mario bros wii would have a spot if it wasn't for the fact that I hadn't played it yet. Super mario bros 2 can happen anytime. Because
its a dream. So it really can happen anytime. The spin offs will be hard to find out. Somone else do it for me. Useong the koopas to tell
what perioud it is. Is helpful.
Done. Their can can anyone see a flaw here?
