A crown group consists of the last common ancestor of a living group of organisms (i.e., the most immediate ancestor shared by at least two species), and all its descendants. By definition, all living members of phyla (representing all the major animal groups today) are members of their respective crown groups. A crown group can also contain extinct animals.
