Calvin held to animal mortality even before the creation of dissimilar and immortal man, the unique image of the immortal Triune God (Genesis 1:26-29). And he regarded God’s continuing seventh formation day as His unended rest in man as His viceroy (Genesis 2:1-3).
John Calvin said Noah’s Flood did not change earth’s topographical contours (Genesis 2:10f & 8:1f). He denied the Deluge caused any dispensationalistic postflood change in the prefall climate or in the diet of man and the animals (Genesis 1:14-30 cf. 8:22 to 9:4). And he interpreted Noah’s Flood in the light of the definitive earlier formation week (Genesis 1:1-31 & 6:17 to 9:17 cf. Matthew 19:4-8) – and not vice versa.
