Amygdalodon addendum




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_?
