“Land animals (which includes dinosaurs) and man were made on day 6 of the creation week. So we lived at the same time” (A Flood of Evidence, p.157)
“So why did dinosaurs die out? The simple answer is sin. When Adam and Eve sinned (Gen 3) death came into the world… Some specific reasons for their extinction likely include environments (e.g. the ice age that followed the Flood, the destruction of swamp lands by man, and so on), predation by man (cf. Genesis 10:9), diseases, genetic problems, catastrophic events, etc” (The New Answers Book 4, p.42)
