What happened to the dinosaurs?

I emailed the Creation Museum a few questions. This is a link they sent for my question, "What about the dinosaurs?":

What happened to the dinosaurs?: "According to the Bible: Dinosaurs first existed around 6,000 years ago. God made the dinosaurs, along with the other land animals, on Day Six of the Creation Week (Gen. 1:20–25, 31). Adam and Eve were also made on day six—so dinosaurs lived at the same time as people, not separated by eons of time. Dinosaurs could not have died out before people appeared, because dinosaurs had not previously existed, and death, bloodshed, disease and suffering are a result of Adam’s sin (Rom. 5:12,14, 1 Cor. 15:21–22).

Representatives of all the kinds of air-breathing land animals, including the dinosaur kinds, went on board Noah’s Ark. All those left outside the Ark died in the cataclysmic circumstances of the Flood—many of their remains became fossils.

After the Flood (around 4,500 years ago), the remnant of the land animals, including dinosaurs, came off the Ark and lived in the present world, along with people. Because of sin, the judgments of the Curse and the Flood have greatly changed the earth. Post-Flood climatic change, lack of food, disease, and man’s activities caused many types of animals to become extinct. The dinosaurs, like many other creatures, died out. Why the big mystery about dinosaurs?"
