Arctic Crocodiles

Could crocodiles have once lived at the North Pole? 

Yes, really a crocodile could survive in the Arctic. But not exactly for the reason you are thinking: 

 

The cocodrile is incapable to do a coat for him. The reason is that in time  in the Arctic will not do much cold.

Experts on Climate Change estimates that the average air temperature of the Earth could warm up to 6.4 ° C towards the end of the century. 

 That would still remain a lot of ice melt in the Arctic for warm-blooded animals cold Crocodiles as might be comfortable, but it's about time.

In any case, it´s not  the first time it happened something similar. 55 million years ago, the Arctic climate was so mild as that of Florida.

Recent studies would seem to suggest that crocodiles may once have lived at higher latitudes than they currently reside today. Since crocodiles are cold-blooded reptiles, where they can survive is directly related to the temperature of the region.

Crocodiles live in tropical climates for a reason. They are cold-blooded and cannot generate their own heat. 

During colder months, they hibernate or go dormant. Crocodiles will also go dormant during long periods of drought. To create a place to hibernate, they dig out a burrow in the side of river bank or lake and settle in for a long sleep
