Most probably one reason that some dinosaurs grew to immense size is that they had an over-abundance of food. (CO2 levels were higher then than today, there was no competition with man and and the climate was temperate).
Another is also that some animals keep growing (sharks, crocodiles) until their size is ballanced by their food input.
