On the right is the skull of the largest known salamander alive today. To the left, the metoposaur skull, said to be millions of years old. Something was obviously different in the past. The metoposaur lived before the flood, when the environment was much more hospitable (not millions of years ago, by the way).
Peter the salamander. Peter is a spotted salamander, about 7" long. Like all amphibians, Peter breathes at least partly through his skin.
The Metoposaur, a giant salamander. In the past salamanders grew to 12 feet in length. The Bible states that there used to be an extra layer in our atmosphere, which would have increased atmospheric pressure. The Bible predicts, therefore, that animals that breathe through their skin, like salamanders, could have grown to enormous sizes.
