Zhongjianornis an enlarged, keeled breastbone in more advanced birds. However, later analysis of the anatomy of "Z. yangi" cast doubt on this interpretation of the bird as very primitive. Research published in 2012 found that some of the apparently primitive features were due to poor preservation of the bones, and that "Zhongjianornis" is more similar in anatomy to primitive euornitheans like "Chaoyangia" and "Schizooura". A phylogenetic analysis showed that a very primitive position in the bird family tree for "Z. yangi" is unlikely given current evidence. Zhongjianornis Zhongjianornis is a genus of beaked, pigeon-sized birds from the early Cretaceous period of
Project anatomy Project anatomy A project anatomy (also integration anatomy or organic integration plan) is a tool for integration planning that visualizes dependencies between work items in development projects. It is mainly used in incremental development and Integration Driven Development projects. The project anatomy has evolved from the system anatomy and in its purest form the work items (called "work packages") reflect the development of system capabilities. Often a more pragmatic approach is taken, though, where work packages may contain other items with important dependencies as well, e.g. HW deliveries for embedded systems.
