A novel, skeletal reconstruction of Archaeopteryx skeleton follows Heilmann's (1926) tradition in being based primarily on osteological evidence and free phylogenetic and functional preconceptions. Although the connection between the sternum and ribs remains unknown, a combination of positional and comparative evidence speaks for the presence of cartilaginous sternal ribs. The reconstructed rib cage is compatible with some levels of the airsac ventilation mechanics. The reconstructed segmental position (relative to the vertebral column) of the shoulder girdle at the level of 11th or 12th vertebra agrees with evidence from both modern birds and theropods. The wing must have been largely folded in the resting position, but the geometry and mechanism of wing folding remain conjectural. In its gait and stance, Archaeopteryx was more similar to the modern birds than to the theropods.
