Ornithothoraces Ornithothoraces Ornithothoraces is a group of avialans that includes all enantiornithes ("opposite birds") and the euornithes ("true birds"), which includes modern birds and their closest ancestors. The name Ornithothoraces means "bird thoraxes". This refers to the modern, highly advanced anatomy of the thorax that gave the ornithothoracines superior flight capability compared with more primitive avialans. This anatomy includes a large, keeled breastbone, elongated coracoids and a modified glenoid joint in the shoulder, and a semi-rigid rib cage. The earliest known members of the group are the enantiornitheans "Protopteryx fengningensis", "Eopengornis martini", and "Cruralispennia multidonta", as well as the euornithine "Archaeornithura
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.
