Containing group: Salientia


†Prosalirus bitis is from the Early Jurassic (Pliensbachian) of Arizona; the putative limbed caecilian †Eocaecilia is from the same formation. It is reputed to be the earliest known "frog" in the sense that it has froglike features such as a urostyle and elongate, anteriorly directed ilia.

This page is a Tree of Life Leaf Page.

Each ToL leaf page provides a synopsis of the characteristics of a group of organisms representing a leaf at the tip of the Tree of Life. The major distinction between a leaf and a branch of the Tree of Life is that a leaf cannot generally be further subdivided into subgroups representing distinct genetic lineages.

For a more detailed explanation of the different ToL page types, have a look at the Structure of the Tree of Life page.
