 Well fine this makes a lot of sence if there was no impact. But frogs 
would still die if they were hibernating while the asteroid hit. The hit 
would cause massive changes in the world's climate as well as changes in 
chemical water balance. This would certainlly kill off many species of 
frogs. Frogs are tough... when they hibernate. But in a world that is 
going through changes, no. I do work a prarie and I can tell you that 
frogs are very very sensitive to any changes in temperature, air, 
water,etc.
