In The Time of Dinosaurs

I was in the Tyrannosaurus's mouth. No room to move. Stinking foul air.
Sticky saliva all over me. A big tongue that tried to push the rest of me down the waiting, greedy throat. He closed his mouth and crushed the air out of my lungs.
I grabbed that tongue. I locked my fingers on the rough, wet thing and focused with all that was left of my terrified, jibbering brain.
I wasn't even sure I'd acquired the DNA when I started trying to morph. I was doing it all at once. I was acquiring and morphing and screaming in terror.
