Environment and extinction in the late Cenozoic of the North Atlantic area - insights from sclerochronology

Sclerochronology is the sister-field of dendrochronology, the study of tree rings. It involves analysis of the size and composition of increments within mineralised skeletons formed by accretion, such as those of bivalve molluscs, corals and coralline algae. Detailed information can be obtained on t...
