Re: T. rex's vision as SUPPORT for scavenging activitiy...
Considering the remarkably limited flexibility of the quetz neck vertebrae
and the shape of the tip of the lower mandible, the stork analog seems
unlikely to me. Prior to assuming a stork analog, I suggest taking an
actual quetz neck and placing the vertebrae in maximum dorsal, ventral, and
lateral deflections. After doing so, I drew different conclusions (which
doesn't mean that quetz wouldn't have picked up a tasty tidbit off the
ground if it stumbled across one).

Dr Naish concludes that, based on the anatomical evidence, "azhdarchids
were stork-like generalists, picking up assorted invertebrate and
vertebrate prey from shallow water and/or terrestrial environments." I
like his line of reasoning, although I doubt it's the last word on the
topic. I hope his blog on azhdarchid ecomorphology, by reference to
modern analogs, gets morphed into a paper.
