Amygdalodon addendum

["Tim Williams" <twilliams_alpha@hotmail.com>]

In the re-description of the type material of _Amygdalodon patagonicus_, 
Rauhut (2003) mentions a curious plate-like bone fragment that Cabrera 
(1947) originally interpreted as a partial scapula.  The bone fragment is 
rather flat and rectangular (and in overall shape bears a vague resemblence 
to the state of Connecticut).  Two of the edges are real and the other two 
broken.  One side of the element is convex, the other concave and has a 
slender, broken-off piece of bone attached to it.

According to Rauhut, the element does not even belong to a sauropod, much 
less _Amygdalodon_, and he lists it as Vertebrata indet.  But I wonder: 
could it be a fragment of dermal armor belonging to _Amygdalodon_?
