dino trunks

<<Is it possible that Diplodocus (or other sauropodes (sic) which have
nostrils highly placed on the skull) can have a trunk like elephants?>>

Reptiles and birds, according to Romer, have few dermal muscles.  Mammals, by
way of contrast, have extensive dermal muscles, especially concentrated
anteriorly, and especially prominent around the eyes, ears and lips.  An
elephants trunk is mobilized by these muscles.  Diplodocus probably lacked
the facial muscles necessary to start a trunk.  

Speaking of John C. McLoughlin, where is he nowadays? And what's he come up
with lately?
