However, some skeletal dysplasias have hypoplastic clavicles (cleido-cranial dysostosis) or scapulae (campomelic dysplasia).
Other features, less easily identified on ultrasound include hypoplastic scapulae, narrow iliac wings and a poorly ossified pubis.
Differs from all other stegosaurs in possessing parascapular spines that are at least twice the length of the scapulae.
Challenges were injected subcutaneously (s. c.) between the scapulae.
The inability to fixate the scapulae prevents full abduction of the arm and gives rise to a rather characteristic appearance around the shoulders when this movement is attempted.
The well-preserved fossil remains include a nearly complete skull, mandibles, vertebrae, ribs, scapulae, and a radius.
This rotation is in the opposite direction to that produced by levator scapulae and the rhomboids.
Whilst believed by many to be a type of gland, it is actually a collection of adipose tissues lying between the scapulae of rodentine mammals.
