The Bible refers to dinosaurs, but it calls them dragons. Dragons are mentioned 37 times in the Bible and six of these are with known real animals. They can be found in:
In these passages the Bible is clearly referring to real animals. Equating dragons to dinosaurs is justified by history, since dragon is what any person before 1841 would have called a dinosaur if they had seen one.
The Bible also describes two of these animals in great detail. The Bible refers to Behemoth in Job 40:15-24 and Leviathan in Job 41
The Bible also has two references that sound vary much like ancient descriptions of Pterodactyl or other flying dinosaurs. In both cases the Bible refers to flying serpents along with known real animals. Today we know from fossils that at some time in the past there were flying reptiles. If Isaiah or any other ancient Israelite had seen a Pterodactyl, they probably would have referred to them as flying serpents.
So the Bible clearly does mention dinosaurs, it uses different names but it does refer to them.
