Archaeology has found many dinosaur fossils. Does the Bible have anything to say about the existence of dinosaurs?
Some commentators (such as the Institute for Creation Research) have suggested that Leviathan (otherwise a Hapax Legomenon) in Job 41 is a dinosaur. Not all agree, but it is at least "out there" as a theory.
Prior to the 1820s, dinosaurs were unknown to (modern) man, so it is not surprising the are not mentioned in the Bible. (Indeed, the term would have had no meaning).
If the case is that Leviathan is a dinsoaur, then we read:
Basically, they are big and strong, but God is bigger.
: To be clear, most scientists believe that man was just a mouse during the age of the dinosaur, and even old earth Creationists suspect that the dinosaurs had died out in the "two days" before man. During the 1800s, I believe it was Paley who suggested that the dinosaurs must have died out shortly after the flood. A few die-hard Young Earthers (like the ICR) still advocate that, but for the most part "The Land of the Lost" is just that.
Technically it is paleontology and not archaeology that is concerned with prehistoric fossils.
There is a (mostly) good book that deals with creation and evolution (among other things) in a complimentary way: http://www.amazon.com/Science-God-Convergence-Scientific-Biblical/dp/1439129584
There is also the Six Dawns essay which does essentially the same thing from an Orthodox perspective: http://www.scribd.com/doc/75080212/The-Six-Dawns-by-Dr-Alexander-Kalomiros
Essentially, the focus is on this particular verse:
We now know from paleontology that some sea creatures evolved into amphibians and reptiles, and some reptiles into dinosaurs, and ultimately some dinosaurs into birds. So the entire age of the dinosaurs is glossed over in this one verse. One could argue that since dinosaurs were extinct by the time this passage was written, their inclusion would have been confusing at best to the people of the time.
Historians believe that dinosaurs lived before humans. Therefore dinosaurs could be simply mentioned during the 2 days when God created the animals. Gen 1:20-25
God could consider dinosaurs simply animals, and there would be no reason for him to explicitly mention them.
