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 evolved from system anatomies, mainly at Ericsson, since the late 1990s. Both the terminology and the methodology have differed between organizations and the difference between "system anatomy", "project anatomy", "delta anatomy" and "integration anatomy" is sometimes diffuse or non-existent. In 2004 FindOut Technologies presented a SW tool (Paipe) for managing anatomies with more properties. The company has, since then, worked to establish the term Project Anatomy. The project anatomy below is an example showing the work packages needed to develop a simple issue management system. Work packages with many dependencies are called spiders and indicate a risk. The risk may
