The scale bar in the figure (Fig. 2) suggests that _Willinakaqe_ was
quite small by hadrosaurian standards: ~ 4m (I presume the restoration
is of the adult).  So this South American hadrosaur was around the
same size as the European  lambeosaurine _Pararhabdodon_.
Interestingly, on p.225 you note that _Willinikaqe_ and
_Pararhabdodon_ each have only eight fused sacral vertebrae as adults,
compared to nine in saurolophids.  Could this be a size-related
feature?  Smaller hadrosaur genera absorbed less vertebrae into the
sacrum?


Nice work, Augusto!
