Baryonyx, like many other large dinosaurs, reduced its weight by 
developing fenestrations in its neural arches as well as pleurocoels in 
q 
its centra. These fenestrations occur in places where the mechanical 
stresses on the vertebra are not sufficiently great to require complete 
ossification of the skeletal structure. Essentially, these locations are 
around the base of the transverse process. Thus, at the proximal end
