List of transitional fossils
- List of 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). An ideal list would "only" recursively include 'true' transitionals, i.e. those forms morphologically similar to the ancestors of the monophyletic group containing the derived relative, and not intermediate forms. See the article on transitional fossils for an explanation of the difference with intermediate forms. Since all species are supposed to be 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.
