http://www.atlanteanconspiracy.com/2015/09/dinosaur-hoax-dinosaurs-never-existed.htmlThis is a conspiracy theory website, but it's an interesting idea. They argue that Sir Richard Owen hypothesized the existence of dinosaurs before any were actually found, then 12 years later, people suddenly started digging up dinosaur bones, people with a vested interest in their discovery. For several decades, there were numerous dinosaur bones finds, always by people who were looking for them. It points out that dinosaur bones in museums are plaster fakes. The real bones are locked away where only people with a vested interest in the public believing in dinosaurs can look at them. No fossils of complete dinosaurs have been found. Much of what we see are just extrapolations by paleontologists
