Dinosaurs and Giant Mammals

I read an interesting article about mammal diversification and gigantism that took place after the dinosaurs kicked off. I've always thought it was cool how certain species trend toward huge size as they elbow the competition out of an ecological niche. Or an ecological corridor in the case of something like Indricotherium or Deinotherium. Amazing creatures.

Deinotherium was a far larger animal than I had known before I read the recent articles about the early explosion of size in terrestrial mammals.
