Paleontology

From Palaeos.org

Paleontology is the American spelling of Palaeontology, the central subject of the Palaeos website.

The word is roughly equivalent to "old life" -- the study of the life forms that existed before 'modern times'. Evidence of these life forms comes to us mainly through the study of fossils.

Any interested person could spend a happy lifetime studying all the possible implications that arise from these fossils -- and enjoy the lively debates that ensue!
