Excerpt from The Rock and Fossil Sequences: A Summary
by Barry Setterfield
"First, a comparison of Genesis 1:29-30; 6:21 and 9:2-5, show that mankind and all the creatures were vegetarian before the Flood. In the Paleozoic, we see many examples of creatures eating each other. This is reproduced numerous times in Mesozoic and Cenozoic strata. So the Flood must have happened before Paleozoic and later strata were laid down."
