One VERY important issue (for which we will have to Wait For The Paper): are
the pedal prints tracks, or are they undertracks? It
might well be that the little dino is running quadrupedally, but we are
sampling layers under the actual muddy surface, which only
the pedal impression reached.
As has been shown by Manning (among many others), knowing if you are dealing
with real tracks or undertracks can make a LOT of
difference in interpretation.
