Re: PISANOSAURUS

Just curious:  The Dinosaur Dictionary (Glut 1972, 1984 edition) says:
Pisanosaurus-...This primitive ornithiscian is known only from fragmentary
material found in Argentina, including limb bones, ribs, metatarsals and
incomplete jaws.
How was it classified as a plant eater and propubic?
Also, because he's not participating in the discussion, I want to quote Norman
as saying that Professor Kermack of University College, London 'collected the
remains of the partial skeleton of a small animal which came from the Upper
Triassic "Red Beds" of Lesotho. ' 
He adds, 'Being of the same geological age as the original Fabrosaurus and
having teeth which seemed virtually identical, this new animal was also named
fabrosaurus australis when it was finally described in detail by Dr Tony
Thulborn.  However, since then this animal has undergone a name change!  It is
now claimed that the original material of Fabrosaurus, since it is only a
small piece of jaw with a few teeth, cannot be closely compared to the newer
skeleton so it is impossible to know exactly how similar these animals really
were.  To be safe, the new skeleton was renamed Lesothosaurus australis.
(Indeed if you look back in some older dinosaur books, you may well find this
dinosaur illustrated and described as Fabrosaurus).'
