WebThe first attempt to construct a biozonation scheme for European mammal-bearing deposits was made by Thaler (1964). Neogene and lower Pliocene sites of southern France and of Spain were concerned, being situated in a series of rodent range zones each designated after the name of its most typical site. Some years later Heintz (1970) proposed a …

In its strict sense, it refers to the use of assemblages of fossils that are not tied to stratigraphic sections (in contrast to biostratigraphy, where they are). Collections of land mammal ages have been defined for every continent except … See more In sedimentary rocks, fossils are the only widely applicable tool for time correlation.
