You know, I'm not sure. I was surprised to see the porcupine in there. As far as I know we only have wombats over by the bactrian camels now, so maybe they moved it over there somewhere.
Ah yes, now that you mention it, I seem to recall seeing a photo of them in the old pacarana exhibit across from the koalas (beside the tree 'roos).
I must say that the porcupine looks spectacular in this exhibit - great shot!
Anything else in with it?
