An example of this class was discovered in China in 1993 and classified as the genus Confuciusornis [kun-FYOO-shus-OR-niss], while an early example in the Americas was the Phorusrhacos [for-us-RAH-kos], which is similar to but larger than modern-day seriemas [sair-ee-AY-mahz].

Jacques Gauthier [goh-tee- ay] claims that this class of animals descended from theropods. These vertebrates have a synsacrum [sin-SAAK-rum] instead of a pelvis, and their constant-volume lungs are supplemented by anterior and posterior air sacs. The earliest known example is the Archaeopteryx [ar-kee-AHP-tur-iks], which like modern examples contained a furcula, or wishbone. Name these animals that include passerines, sandgrouse, loons, cranes, and storks.
