Paleoecology uses data from
fossils and subfossils to reconstruct the ecosystems of the past. It includes the study of fossilorganisms and their bromalites and other trace fossilsin terms of their life cycle, their living interactions, their natural environment, their manner of deathand burial. Paleoecology's aim is therefore to build the most detailed model possible of the life environment of those living organisms found today as fossils; such reconstruction work involves complex interactions among environmental factors ( temperature, foodsupplies, degree of solar illumination, etc.). Of course, much of this complex data has been distorted or destroyed by the post-mortem fossilization processes, adding another layer of complexity. The environmental complexity factor is normally tackled through statistical analysis of the available numerical data (quantitative paleontologyor paleostatistics), while the study of post-mortem processes is known as the field of taphonomy.
Much paleoecological research focuses on the last two million years (the
Quaternaryperiod) because older environments are less well-represented in the fossil timeline of evolution. Indeed, many studies concentrate on the Holoceneepoch (the last 11,000 years), or the last glacial stage of the Pleistoceneepoch (the Wisconsin/Weichsel/Devensian/Würm glaciation of the ice age, from 50,000 to 10,000 years ago). Such studies are useful for understanding the dynamics of ecosystem change and for reconstructing pre-industrialization ecosystems. Many public policydecision-makers have pointed to the importance of using paleoecological studies as a basis for choices made in conservation ecology.
