Description
Summary:Ancient terrestrial ecosystems cannot be observed directly because they no longer exist. None the less, a wide variety of approaches and techniques have been developed to provide indirect physical and chemical evidence for many aspects of their functioning, as for example, about the climate, vegetation structure and fauna of a particular place and time. Stable isotopes, which are atoms of the same chemical element with different atomic mass, are contained in the tissues of living beings and can be used as paleodietary and paleoecological indicators since they preserve the chemical signals of the resources incorporated by organisms which are also related to weather conditions. Teeth constitute a large part of the fossil remains found in paleontological sites, as they are less susceptible to being destroyed or modified by diagenetic processes, in comparison to other tissues. Teeth are structures that have an organic and an inorganic phase, the latter composed of bioapatite...
