In The Time of Dinosaurs

The tree trunk was no more than a foot in diameter.

[...]

The Tyrannosaurus chomped its jaws shut on the tree itself. He began to twist and rip the tree, like a dog with a bone. Rending, tearing, bark flying, white wood pulp chewed to chips.
In a few seconds the tree would no longer be between us. And already I was too far morphed to run to another tree.
"Grrr-UNCH! Grrr-UNCH! Scree-EEEE-EEEE-crrUNCH! RrrrOOOAAAARRR!"
The Tyrannosaurus had gone mad with frustration. It was screaming in rage, ripping, grinding, throwing its huge weight back and forth.
Shaking the ground. Bruising the air with its insane roar. Just a few seconds more and . . .
Crrr-SNAP!
The tree fell slowly away, crashing down through layers of vines and ferns.
