A scientist has a fossil that was found in a layer of rock close to Earth’s surface. He believes that the fossil is around 12,000 years old. Which method would best allow the scientist to confirm the actual age of the fossil?

Who developed the theory of plate tectonics?

15 points need quick 1. looking at your graph and the geologic time scale during what period did this rock form? what is the age span of the rock, in millions of years? 2. this rock sample is limestone and shale. with what you know about rock formation, what type of environment did these organisms live in? 3. if some of these fossil samples were found in a rock also containing leaf fossils, could you use radiocarbon dating to determine the age of this rock? explain.
