A very good question. Have you ever read the book of Job? Chapters 40 and 41 describe animals that one could logically view, in at least one instance as a Sauropod. Drawings and carvings have been found all over the world of dinosaurs that date at least to the 11th century. Some, much later. Scientists got their looks wrong on a regular basis since they rarely found any intact fossilized specimens. Also, you within fossil beds containing dinosaur bones, many mammalian fossils were also found. There was also a human footprint fossilized inside a dinosaur footprint in Texas. What fossilized bones tells us is better explained in the global flood account. A catastrophic event is indeed required to kill so many creatures and they must be buried very quickly to preserve the bones. There is at least one fossilized fish in the act of giving birth and another that is eating another fish.
