Assessing the preservation of biogenic strontium in fossil bones and tooth enamel
Abstract Analyses of the strontium isotope ratio ( 87 Sr/ 86 Sr) of vertebrate fossils can provide information about palaeobiological attributes such as habitat use and movement patterns. Diagenetic contaminants can alter the 87 Sr/ 86 Sr ratio of fossils, however, complicating palaeobiological inte...
