First, you need to tune into God and listen to Him. He is not interested in convincing us about dinosaurs. God wasn't even interested in giving you a blow by blow and time by time account of His method of creating you and the earth, and you wouldn't understand it anyway. If you read Genesis, chapter one, and ask God to explain exactly how he managed creation you will find it just doesn't do that, isn't meant to do that. All you are really going to get is God did it.
God wants you to think of time as you know it in increments of seven days. God sees time differently, and it is pretty hard for our human minds to even conceive of that for God's time is eternal time. For God, things just are instead of happening one by one as we see it. And if that is hard for you to conceive of, just think how hard it would be for God to give you manufacturing instructions of earth and human building.
I have heard of one theory of dinosaurs that I've been told won't really hold water, but here is a theory. We know the atmosphere of the earth was different before the flood. Everything was in a mist, and the oxygen content of the air was different. Also, people lived much longer. Perhaps animals did, too, and grew to great size.
Taking parts of this theory into today, hospitals have units called hyperbaric oxygen therapy. They put such as burn victims in special tanks, regulate the oxygen and it creates a miracle of healing and enabling plants to grow.
The point is that God gives us information based on our need to know. You need to know God created you.
It was thousands of years after the bible recorded history of people before the type of thinking developed that you are doing, in fact it started about 800 years before Christ. That is when language started having words for emotions without including the doing those emotions produce. That was when people started asking why, where, when instead of, is that so, well how can I use that fact.
I hope I have convinced you to not tie your quest for dinosaur knowledge with God knowledge.
