Re: If the asteroid had missed...
Dinosaurs are still here...they are just no longer competitive in the large
animal niche. Predatory tactics of birds, mammals, and reptiles are probably
prohibitive for any animal whose nest is dependent upon defending a nest in the
open field (crocs having the advantage of ambushing a nest predator _and_
seeing very well at night...a luxury probably not afforded most dinosaurs).

hitting the Earth - but what would have happened if the giant space rock
"They were the superlatives; they were the biggest, the heaviest, the
meanest, the longest. You name it, dinosaurs were it," says fellow
palaeontologist Phil Currie, from the University of Alberta in Canada, who
has access to one of the richest areas of dinosaur research in the world.
"The badlands of Alberta clearly show that at the end of the Cretaceous,
dinosaurs were extremely successful still," says Professor Currie, who
points to dozens of different dinosaur species living in that one
environment at the same time.
Had the asteroid missed, he believes, dinosaurs would have continued to
"We wouldn't have the modern animals that we're used to. Giraffes and
elephants and so on; they just wouldn't have evolved because dinosaurs
would still be here," says Professor Currie.
