From: The relationship between sternum variation and mode of locomotion in birds
A 3D model of sternum from Ramphastos ambiguus with anatomical labels showing noteworthy regions on the sternum, with landmarks (larger yellow spheres) and semi-landmarks (smaller yellow spheres) along edges and curves, with the lateral view on top and ventral view below. Abbreviations: cp, craniolateral process; it = intermediate trabeculae; k, keel; lt, lateral trabeculae; m/rs, manubrium/rostrum sterni; rf, rib facets; sn, sternal notches; xp, xiphoid process. B Landmarks extracted from the 3D model, with the lateral view on top and ventral view below. More detailed figure of landmarks provided in Additional File 1 Figure S1. Scale bars: 10 mm
