Osteological correlates of Mm. levator scapulae and serratus profundus in Sauropodomorpha.
Cervical vertebrae showing putative origin site of Mm. levator scapulae (if present) and serratus profundus in Pantydraco caducus (NHMUK RU P24)(A); Plateosaurus engelhardti (GPIT1)(B); Erketu ellisoni (IGM 100/1803; C3 and C4 reversed from right)(C). The arrow denotes the lateral surface of the diapophysis-rib complex where Mm. levator scapulae and serratus profundus would have been attached. Not to scale.
