I'm responding to the OT. The word used in Genesis for day, could also be translated era or period of time. So it wasn't a literal 24-hour period of time each "day". (And actually there is another word entirely that refers to the 24-hour day and it wasn't used in this account.) In addition it was not written to be scientifically accurate with this animal appeared here, because such information wouldn't of been useful to the audience that read it during in the day it was written. But the account does give the audience of that time a good look at what happened on earth during the six creative periods, without getting into the details. (The book was written in 1513 BCE by Moses) And actually the account has be lauded as a very good narrative of what happened as a observer standing on earth and going through the millions of years even down to when the animal groups appeared on the planet. Because if you read Gen 1:1 you find that the universe was already created even before the 6 periods began.
The dinosaurs appeared during the period of Gen 1:20-22 and disappeared by what ever mechanism brought their extinction during that time also. Its speculation but the dinosaurs were essentially used to maintain the plant-life so it didn't over run the planet and endanger to emergence of the mammal family, and once their task was done they were disposed of, for a lack of a better term.
Paladin's response is good and really the ony one necessary. So many Christians and non-Christans alike have so little understandng or knowledge of what is in the bible and what it's about. So many also seem to think it was written in English, which is quite honestly pretty funny. If you are Christian, the bible tells you that God made light, the oceans, then land, then creatures and plants, then humans. Humans lived in blissful ignorance until through their own desire became self-aware and intellient. Take that what you will. It doesn't say there was or wasn't dinosaurs (or any other animal), that evolution was or wasn't how animals adapted and changed, and it doesn't say it all happened in a day or days. The term "day" is just how it was translated years later.
