Why Crocodiles survived Dinosaurs by 65 million years?

• Crocodiles learn very quickly and adapt to changes in their environment. In particular, they quickly learn to avoid dangerous situations. In fact, it is tough to catch a crocodile twice using the same trick.
• Crocodiles learn by observing behavior. They recognize a pattern when animals come to the river to drink at the same time each day.
• Crocodiles cooperate in food gathering by forming their bodies into a dam to catch fish. They take turns with larger prey – one holds while the other eats.
• Crocodiles have community nurseries in which one mother watches over the hatchlings of many. They live and work as members of a group.
  
  The message is very clear to their recent (the last 100,000 years or 0.1 million year) fellow species, Homo sapiens, if they hope to survive at least few million years, if not 65.
