Carbon 14 can be used to date anything that was alive and died no more than 40 to 50 thousand years ago. This limit is because of the shorter half-life of carbon 14.
In the case of older fossils, other methods are used, simulteneously, and their correlation with each other determines the age of the fossil. Certain fossils are known to have existed within certain time periods, and are known as index fossils. The presence of index fossils within the same strata as, say, a dinosaur bone, are an excellent indication of the approximate age of that fossil, and when other methods are also used, a fairly accurate date can be concluded for the fossil.

Carbon 14 dating can be used to date anything that has traces of carbon in it. That includes bones.
