Title:	Carbon isotopic evidence for difference feeding patterns in two hyrax species occupying the same habitat
Date:	1978
Source:	Science
Abstract:	The carbon-13/carbon-12 ratios of the carbonate and collagen fractions of bone of the sympatric hyrax species Procavia johnstoni and Heterohyrax brucei indicate that the former obtains most of its diet by grazing while the latter is primarily a browser. The carbon-13/carbon-12 ratios of these fractions in fossil bone will record information about diet if they have not been altered during diagenesis.
