only 4 in (10 cm)

egg nest. Oviraptor was about
6 ft (1.8 m) long.

The end of each long finger Chirostenotes
was equipped with a slender,

feathery bodies and tails and long feathers on bony projections on the roof of the mouth that

often toothless beaks, which they may have used maybe they were egg thieves after all. 117
