What happened to the dinosaurs?

from the old testament

• "Dinosaurs" is a modern term, so Scripture doesn't use it. But "Behemoth" and "Leviathon" as described in Job (Job 40:15–24, 41) may be examples of what we call "dinosaurs."
• The Bible indicates that God created animals—which would have included dinosaurs—on the sixth day (Genesis 1:24-25).
• Factors that may have contributed to the extinction of dinosaurs were environmental changes post-flood (Genesis 2:5–6) and the fact that human beings began to hunt and eat animals (Genesis 9:2–3).
• Some are skeptical about dinosaurs being on the ark God told Noah to build (Genesis 6). But many dinosaurs were no larger than the average horse, and it's plausible that Noah brought young ones.

from the new testament

• The Bible offers no evidence of dinosaurs during the New Testament era, indicating that they were likely extinct by then. Their extinction is another example of the fallen world, which impacts humankind and all of creation (Romans 8:20-21).

implications for today

For twentieth-century kids, dinosaurs are big, purple, and sing or are toys found in Fruity Pebbles. That makes it hard to think of them as real creatures who once roamed the Earth. Some Bible skeptics point to dinosaurs to argue against the Bible. But the existence of dinosaurs isn't incompatible with a biblical worldview.

In fact, the Bible provides a reason for the extinction of such creatures: the fall.  Sin infected all of creation. Paul writes about the "futility" creation was subjected to (Romans 8:20) and the glorious promise that "creation itself will be set free from its bondage to corruption and obtain the freedom of the glory of the children of God" (Romans 20:21). Because Christ paid the price for our sin, we and all of creation will be free from sin one day—no death, no extinction.
