The exact reference is:

Molnar, R.E. (1996).  Observations on the Australian ornithopod dinosaur 
Muttaburrasaurus. Mem. Queensland Mus. 39: 639-652.

That would be neat!  (Especially since the Hypsilophodontidae looks like 
being carved up anyway in the near future.)  The similarities noted by 
Molnar are in the teeth.  In fact, says Molnar, for a second 
_Muttaburrasaurus_ skull (QM F14921, _Muttaburrasaurus_ sp.) the teeth are 
strikingly similar to those of _Atlascopcosaurus_.  The  development and 
arrangement of ridges on the maxillary teeth in QM F14921 are in some ways 
more similar to the teeth of _Atlascopcosaurus_ than the holotype of 
_Muttaburrasaurus_.
