Description | Content |
Article description: (description ) This attribute controls the content of the description and og:description elements. | In paleontology, the word "Amphibian" has traditionally had a much broader meaning than that commonly attributed. Amphibians have been all Tetrapods ("four-limbed vertebrates") excluded "reptiles" and the latter's descendants, Birds-Mammals. Today, even scientists tend to restrict the world to indicate only modern Frogs, Salamanders, Caecilians, and their common ancestors. If you want to use "amphibians" in its former, broader sense, you have to call modern groups "Lissamphibians". We'll use here amphibian in the old, wider meaning because it's far much handier to say this rather than "basal tetrapod" every time we refer to non-frog, non-salamander, and non-caecilian, animals. |
