You've got to wonder why so invincible an animal is now extinct. Did he run out things big enough to eat? Were the compact models more adaptable?

No...what happened is the croc' ran into my mother-in-law. The rest is history.

My guess is that the dinos went down after a big asteriod and with it so did the croc food source.

Sounds like this dude could eat anything..how do you defend against a school bus size croc with body armor, five foot jaws and a natural advantage momentum wise- being so low to the groud.

My uneducated guess is that they fell victim to changing weather patterns which interrupted their ability to reproduce. Modern crocs are pretty dependent upon just the right temperature for reproduction.
