The short answer is that although all three are considered reptiles, turtles are outside of the group that includes crocodiles and dinosaurs. This is due in part to the fact that they possess no holes in their skulls behind their eyes, this is called the anapsid condition. Dinosaurs and crocodiles are both diapsid reptiles and have 2 holes behind their eyes. This feature is also found in lizards and snakes. Dinosaurs and crocodiles are also archosaurs, which is a large group of mostly extinct reptiles that includes the ancestors of dinosaurs, pterosaurs, crocodiles and many other interesting animals. Only crocodylians and birds (which are living theropod dinosaurs) survive now.
So although crocodiles and dinosaurs are related more closely to each other than either is to other reptiles such as lizards or snakes, they are still two very different types of animal.
Major differences include specializations in the skull and postcranial skeleton that separate the two. The ancestors of crocodiles however, were very "dinosaur-like" and walked fully upright, many bipedally (or on 2 legs).
