Subgroups

Avebrevicauda (meaning "birds with short tails") is a group of stem-birds which includes all avialan species with ten or fewer free vertebrae in the tail. The group was named in 2002 by Gregory S. Paul to distinguish short-tailed birds from their ancestors, such as Archaeopteryx, which had long, reptilian tails.[1]
