Annex 7: Transitional Fossils

This is a very tentative list of transitional fossils (fossil remains of a creature that exhibits primitive traits in comparison with more derived life-forms to which it is related). Since all species are in transition due to natural selection, the very term “transitional fossil” is essentially a misconception. But the fossils listed represent significant steps in the evolution of major features in various vertebrate lines, and therefore fit the common usage of the phrase.
