@joshua feathers. ALWAYS Feathers. if people tell you "but dinos aren't scary with fluffy feathers!!" just take them to a random farm with geese that they've never been introduced to, and make sure they get nice and hissy and honky, and then say "Just imagine one of these murderous bastards, but thirty foot tall. Scared yet?" If they say no, THEY ARE LYING.
@joshua good answer. YOU HAVE PASSED THE TEST.
