The oldest fossil of dinosaurs occur in rocks that are approximstely how many million years old?
The oldest dinosaur fossils date from the Carnian stage of the Triassic period. That was around 220 million years ago. The first dinosaurs were small carnivores, like Eoraptor, and small, long necked herbivores called prosauropods.
Where have they found fossils of diplodocus dinosaur?

Who is Ed Conrad?
Ed Conrad is a layman who in the early 1980s discovered some rocks in a coal field which he believes are human skulls which date back 280 million years or so, 200 million years before modern science claims that man evolved. These rocks have been examined by scientists, including those at the Smithsonian Institute, who have reported that the rocks are just rocks and not of human origin, but Conrad persists in believing there is a mass conspiracy among anthropologists and paleontologists to keep it secret as to when man actually first appeared on Earth. He posts regularly in several Usenet news groups devoted to the origins of man, frequently changing his username to get around the filters that people set to avoid his posts.

The rocks of "greenstone belts" some of which date to almost 4 billion years ago are the oldest intact rocks. Some individual zircon crystals found in much younger rocks date to 4.4 billion years ago.
How do you carbon date rocks 10 million years old?
You cannot. Carbon dating is not useful for dating things more than about 50,000 years old. You would have to use a different radioisotope to date something 10 million years old. Potassium-Argon dating would work for some rocks.
How did they find out that Stegosaurus lived in 145 and 155 million years?
Stegosaurus fossils actually date to between 155 and 150 million years ago. Using various methods, paleontologists are able to determine the age of rocks. Then they know that fossils in those rocks are the same age as the rocks. In the case of Stegosaurus, they know the rocks are between 155 and 150 million years old, and they know the Stegosaurus fossils are the same age.
How many years did the dinosaurs live before extinction?
Dinosaurs died around 65 million years ago. Although, the first real dinosaur is about 235-240 million years old. It is hard to give an exact date since they are simply rocks.
