Scientists have come up with multitudinous theories as to why these HUGE strong carnivorous beings couldn't survive...
The Ice Age? Really... are we sure it's not actually Global Warming a.k.a. Global Climate Shift?
Earthquakes and Tar Pits. I actually could see the Tar Pit thing... I envision the dinosaurs to be like lemmings - all following each other into a huge tar pit... and even the last guy doesn't think "hmmm... I wonder why nobody has come out the other side?"
Meteors. All I can say is that there is obviously some high galactic sniper power because that's some sharp shootin' Sam!
But because I am uber-brilliant (despite the fact that I just started a sentence with the word "but") I have figured it out... no more debate necessary. I think it's because the dinosaurs "changed teams" - in the days before In Vitro and adoption this would have been devastating to a species.
Do we really need an exhibit B?
