Fig. 39 Baryonyx walkeri, holotype, BMNH R9951; ventral elements of pelvis. A, left pubis lacking proximal end, posterior view; B, left ischium lacking) 
distal end, lateral. x 0.25. 
The distal part of the left pubis is also flattened, with fairly thick, 
rounded edges; but it seems likely that the plane of flattening was 
somewhat different from that of the central fragment, parasagittal 
rather than transverse, from which we infer that there must have 
been some degree of torsion between the two pieces. This means that

tively, and the positions of the two edges would have been anterodorsal 
and posteroventral; meanwhile the blade shows a distinct curvature 
towards the midline as it approaches its distal end. The anterodorsal 
edge thickens towards the distal end, its medial and lateral margins
