Chordata (kingdom Animalia) A large phylum comprising the animals that possess a rod of flexible tissue (notochord), which is protected in higher forms by a vertebral column. The phylum includes Urochordata (tunicates), Amphioxus, fish, amphibians, reptiles, birds, and mammals. The first chordates and the earliest vertebrates are both found in Cambrian rocks.
