Genesis 7:21

And all flesh died that moved upon the earth, both of fowl, and of cattle, and of beast, and of every creeping thing that creepeth upon the earth, and every man:

1. As a result of the flood all flesh - that is, all birds, cattle, beasts, creeping things and man, except those in the ark, died.
2. Any species of land animal or bird that Noah didn't have in the ark, if there were any, were now extinct.
