The clavicula is a rod-like bone that articulates with the lower end of the scapula in an immobile joint. It has been controversial if the left and right clavicles of sauropodomorphs were attached to each other at their ends, thus connecting the left and right shoulder girdles, or if they were pressed against their scapulae along their lengths. The orientation of the clavicle in <i>Sarahsaurus</i> confirms that the former was the case; the ends of both clavicles would probably have been connected to each other by a <a href="/wiki/Ligament" title="Ligament">ligament</a>, though they were not fused. In side view, the scapula was tilted between 45° and 65° relative to the horizontal. This would have allowed the left and right coracoids to almost touch each other at the body midline, while the left and right sterna, which were attached to each other at the midline, would have been located directly behind the coracoids.<sup id="cite_ref-Sarahsaurus_2-7" class="reference"><a href="#cite_note-Sarahsaurus-2"><span class="cite-bracket">[</span>2<span class="cite-bracket">]</span></a></sup><sup id="cite_ref-marsh2018_1-5" class="reference"><a href="#cite_note-marsh2018-1"><span class="cite-bracket">[</span>1<span class="cite-bracket">]</span></a></sup> </p><p>The <a href="/wiki/Humerus" title="Humerus">humerus</a> (upper arm bone) was more than half the length of the <a href="/wiki/Femur" title="Femur">femur</a> (upper thigh bone), and had a large crest on its front side for muscle attachment, the <dfn><a href="/wiki/Glossary_of_dinosaur_anatomy#deltopectoral_crest" title="Glossary of dinosaur anatomy"><span title="See entry at: Glossary of dinosaur anatomy § deltopectoral crest" style="color:inherit;" class="glossary-link">deltopectoral crest</span></a></dfn>, which extended for half the length of the bone and had an S-shaped edge.
