What evidence is there from fossils to suggest that reptiles lived before mammals?

Because the skeletons of what we believe to have been reptiles have been found deeper in the earth than the skeletons of what we believe to have been be mammals.

I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
