1-Ton Snakes Once Slithered In The Tropics : NPR

The loss of megafauna weighs heavy on my heart.  The world would be a more exciting and interesting place with wooly mammoths, giant sloths, saber-tooth tigers, and 1-ton snakes.

Having owned and travelled in a school bus for a time, it's especially evocative to hear that Titanoboa cerrejonensis grew as long as a school bus and ate crocodiles whole.  Of course, this doesn't always end well for the snake.
