What they UTTERLY failed to point out was that:
a) Chatterjee's "protoavian" is explicitly labelled as a dromaeosaur in the
captions;
b) Chatterjee is a very strong advocate of the dinosaurian origin of birds;
c) Chatterjee's position is supported by his own numerical phylogenetic
analysis.
Since the majority of the people at the symposium were not paleontologists,
they had no way of knowing that they were being misled. The figure used to
illustrate the "dichotomy" of the position was itself one that blasts that
dichotomy: a trees down, cladisitic, dinosaurian origin.
