How would life be different had dinosaurs not been wiped out?

We wouldn't be here

Because dinosaurs kept mammals from evolving into anything more, we would not have come had the dinosaurs lived. Consider it an act of God or such, but with the dinosaurs, I wouldn't be talking to you right now.

We would have stayed very small mammals like purgatorius or such. (I really love saying "or such")

WIZ197 - Welcome to SCIFIED! It is always quite agreeable to see new faces! With regards to your question: you have raised a most compelling notion - one that also holds the possibility to be quite frightening. Step back for a moment and consider the ever-changing world and its biology. Were the dinosaurs to have maintained their empire over the world rather than taking a ride to dino heaven on the back of a rogue comet, mother nature of today's world would very likely be a much more savage and nightmarish entity. Consider the fact that the dinosaurs were caught off at the peak of an evolutionary arms race - a battle of attrition to develop the best weapons and defenses. The natural world is ever seeking to improve its life-forms' capabilities to survive, thus the dinosaurs would likely have become something totally unrecognizable to us over the intervening 65 million years after being spared God's curve ball. In their place would almost certainly be something dreadful; evolutionary survivors born from millennia of unrelenting carnage. Perfected for the singular purpose of killing and/or avoiding death. I do not think we would like what we would see.

    I certainly hope this information helps with your project! Once again, welcome to SCIFIED! :)

I'd have to agree with SR.  Maybe T-Rex would evolve into the V-Rex from King Kong :D

Some scientists theorories that at least one type of dinosaur would be able to evolve and have  intelligence to modern humans.   Humans would be non existent.   

 very cool

Thanks guys! I have done some research into the topic, but part of the project has to include primary data. So far I have emailed six people who I think might be able to help me, but I haven't heard back from anyone * queue sigh*. But I think it's a really interesting topic to look at so I will continue on!
