The noise in the air was caused by a great flock of teensy-tiny 
Pteranodons, though instead of smooth reptilian skin their wings were covered 
with oversize scales, and they had toothless, bony beaks instead of proper 
mouths. These miserable things—
these airborne crumbs—were swarming all around Pteranodon, getting in 
his eyes, pecking at his wings, and it was all he could do to keep 
airborne.
