I'm no expert on dinosaur tracks (he says before commenting anyway) - but I 
thought one of the 
ways you can identify an ornithopod track was that the two outer toe imprints 
join at the "heel" at 
a roughly 90 degree angle. That seems to be the case for the first image shown 
in the above 
article. What then suggests that it is a theropod track?
