According to some new discoveries, the dinosaurs’ famed (or maybe infamous) 150 million years (or so they say) of world domination was just luck, in much the same way as human domination for the last 1 million years or so.  Scientists described that if they were around during the early days of the dinosaurs, it would seem like the crurotarsans, who  BTW are the ancestors of crocodiles, would appear to be the dominant group, just like if they had been there during the late Cretaceous it would seem the dinosaurs would rule the planet forever.  Instead, a rather obscure (well, nobody talks about it as much as some others) extinction that occurred about two hundred million years ago ended up being a huge setback for the crurotarsans (though do remember that they still came out with ferocious creatures like Deinosuchus, who can fight with T-Rex and win!).  Previously, it was thought that the dinosaurs were the superior creatures since they evolved more quickly and dominated the planet for about 150 million years.
