Figure 9. A in Functional morphology of neck musculature in the Tyrannosauridae (Dinosauria, Theropoda) as determined via a hierarchical inferential approach

Figure 9. A, insertions of (dark grey) m. longus colli dorsalis pars cranialis onto anterior cervical epipophyses of Haliaeetus leucocephalus. B, schematic origin (light grey) of m. longus colli dorsalis pars cranialis, from cervicodorsal region of Struthio camelus. C, schematic origins (dark grey) of m. longus colli dorsalis pars cranialis from epipophyses (processes dorsales) of posterior cervicals in Struthio camelus. Slips from these origins coalasce with the main belly of the muscle, as demarcated by the light-shaded lines. The main belly of the muscle continues dorsally. D, schematic origin and insertions of m. longus colli dorsalis pars caudalis. This muscle subsystem originates from the cervicodorsal region and sends multiple bellies to insert on posterior cervical epipophyses. E, origins of m. longissimus cervicis/m interarticulares of Caiman crocodylus. The gradient-filled slips represent association of origins with the fascia surrounding the muscles. F, anteriormost insertions (dark grey) of m. longissimus cervicis/m. interarticulares, and m. transversospinalis cervicis, of Caiman crocodylus.Published as part of Eric Snively & Anthony P.
