Why is 14C dating a good method to use for dating a human leg bone but not so good a method for dating a dinosaur bone? You may have to check the dates of the existence of humans and dinosaurs on earth on a chart showing the geological eras.

OpenStudy (aaronq):

C-14 dating has a limit of about 50,000 years because there is very little C-14 left, too little to be able to accurately detect. Dinosaurs were present on earth much earlier than that.
