The topic of dinosaurs in the Bible is part of a larger ongoing debate within the Christian community over the age of the earth, the proper interpretation of Genesis, and how to interpret the physical evidences we find all around us. Those who believe in an older age for the earth tend to agree that the Bible does not mention dinosaurs, because, according to their paradigm, dinosaurs died out millions of years before the first man ever walked the earth. The men who wrote the Bible could not have seen living dinosaurs, which is not biblical.
Those who believe in a younger age for the earth tend to agree that the Bible does mention dinosaurs, though it never actually uses the word “dinosaur.” Instead, it uses the Hebrew word tanniyn, which is translated a few different ways in English Bibles as “sea monster,” or “serpent.” It is most commonly translated “dragon.” The tanniyn appear to have been some sort of giant reptile. These creatures are mentioned nearly thirty times in the Old Testament and were found both on land and in the water. In addition to mentioning these giant reptiles, the Bible describes a couple of creatures in such a way that the writers may have been describing dinosaurs. The behemoth is said to be the mightiest of all God’s creatures, a giant whose tail is likened to a cedar tree (Job 40:15). Dinosaurs like the brachiosaurus and the diplodocus, had huge tails which could easily be compared to a cedar tree. Nearly every ancient civilization has some sort of art depicting giant reptilian creatures. Petroglyphs, artifacts, and even little clay figurines found in North America resemble modern depictions of dinosaurs. Rock carvings in South America depict men riding diplodocus-like creatures and, amazingly, bear the familiar images of triceratops-like, pterodactyl-like, and tyrannosaurus rex-like creatures. Roman mosaics, Mayan pottery, and Babylonian city walls all testify to man’s trans-cultural, geographically fascination with these creatures. In addition to the substantial amount of anthropic and historical evidences for the coexistence of dinosaurs and man, there are physical evidences, like the fossilized footprints of humans and dinosaurs found together at places in North America and West-Central Asia. So, are there dinosaurs in the Bible? The matter is far from settled. It depends on how you interpret the available evidences and how you view the world around you. If the Bible is interpreted literally, a young earth interpretation will result, and the idea that dinosaurs and man coexisted can be accepted. If dinosaurs and human beings coexisted, the Bible does not discuss the issue. Dinosaurs likely died out sometime after the flood due to a combination of dramatic environmental shifts.
