God created everything with a purpose. God created dinosaurs.
God killed everything except for what was on that ark and there are no dinosaurs today. God killed the dinosaurs at the flood. Either that, or you have to believe the earth is much older than the Bible indicates that it is and that while all of the science of evolution is false, science somehow gets the general facts about dinosaurs right.
Actually, science doesn't get dinosaurs right. They are still finding things that are very surprising. Enjoy.

This shifting perspective clicked with Schweitzer's intuitions that dinosaur remains were more than chunks of stone. Once, when she was working with a T. rex skeleton harvested from Hell Creek, she noticed that the fossil exuded a distinctly organic odor. "It smelled just like one of the cadavers we had in the lab who had been treated with chemotherapy before he died," she says. Given the conventional wisdom that such fossils were made up entirely of minerals, Schweitzer was anxious when mentioning this to Horner. "But he said, 'Oh, yeah, all Hell Creek bones smell,'" she says. To most old-line paleontologists, the smell of death didn't even register. To Schweitzer, it meant that traces of life might still cling to those bones.
She had already seen signs of exceptional preservation in the early 1990s, while she was studying the technical aspects of adhering fossil slices to microscope slides. One day a collaborator brought a T. rex slide to a conference and showed it to a pathologist, who examined it under a microscope. "The guy looked at it and said, 'Do you realize you've got red blood cells in that bone?' " Schweitzer remembers. "My colleague brought it back and showed me, and I just got goose bumps, because everyone knows these things don't last for 65 million years."
