| contribution of collagen stable isotope biogeochemistry to the paleobiology of extinct endemic vertebrates from tenerife (canary islands, spain). | the paleodiet and paleoenvironmental context of two extinct species from tenerife island, one giant rat canariomys bravoi and one giant lizard gallotia goliath, have been investigated using carbon and nitrogen isotopic compositions of fossil bone collagen. preliminary to this study, a calibration of the isotopic variations of bone collagen from modern rat rattus rattus, rabbit oryctolagus cuniculus and lizard gallotia galotti relative to environmental conditions on tenerife islands has been atte ... | 2003 | 14521281 |
