Perhaps I drifted off at some point during the 'Dinosaur' programme, but the programme that was on immediately before it was all about tiny creatures. A key claim in the 'Dinosaur' one was that all the small animals were able to thrive once the giants had been eliminated.
I can't imagine that Tyranosaurus Rex ate voles, so how were the latter so much better off? There is also the point that small creatures seem to spend an inordinate amount of time just eating. Given that vegetation also seemed to decline disastrously under the dark cloud that followed the asteroid crash, how did the littluns even survive and pick up the threads of existence once more?

Mikey, if you like interesting programs have a look at "The Rise of the Continents".
The first episode was on BBC2 yesterday afternoon but is on iPlayer catch up.

The second episode is on THIS afternoon (Tuesday) on BBC at 4:15pm followed by episodes 3 and 4 on Wednesday and Thursday.
The programs were made in 2013 so you may have seen them before but he covers how the various land masses (continents) around the world were formed and how they are still moving and colliding in to each other.
He explains how one single lane mass (what we call Pangaea) existed millions of years ago but then split up to form all the continents. And all the land masses are still moving.
He goes all over the world visiting lots of places and the camera work is stunning. He goes up volcanoes, under the earth in Australia, deep in the ground in New York, and flies over Everest.
And you wont believe the fossil he finds in the desert next to the pyramids (I wont say what it is and spoil it).
It is an amazing series of programs and will totally change the way you view the "earth" and all its land masses.

in any period of the planet's history, you'll find animals that occupy and dominate a particular niche; there have always been vast herds of grass eaters on the open savannah, long necked leaf eaters, top predators, etc. in the cretaceous most of these niches were occupied by dinosaurs; with them gone, mammalian equivalents quickly evolved to take their place.

Mikey read somewhere that if the asteroid that fell in the region of Cenral America had hit a few seconds later, it would have impacted the sea rather than the land. And the the dust cloud would not have happened. The dinasaurs would probably not been wiped out. And evolution changed. We would not be here.
