What specimen is this — the reveal!

May 2, 2013

Yesterday I asked whether anyone could identify this specimen:


There was an interesting range of suggestions, but I suppose no-one will be surprised to hear that Darren Naish was the first to make real progress, saying “Hey, that’s a loooong pelvis… I smell macropod.” From there it was a short leap to William Miller asking “Could it be that wallaby from way back in Things to Make & Do part 3?”

Yes it could, William — you win ten shiny new SV-POW! dollars.

It is indeed Logan the wallaby from waaay back in late 2009. Here’s how I butchered him, and some detail on his feet, and how his skull  turned out. Back then I prepped out a forelimb and a hindlimb, the skull and first few cervicals, and the tail (which I don’t think we’ve ever featured here — I should fix that.) When I ran out of time to work on the rest of the specimen, I just dumped it in a plastic tub, added water, and left it for nature to do the work for me. The plan was to fish out the goodies a few months later, but it seems that while my back was turned, three and a half years have passed. I should get on that — if the bones haven’t softened to the point where they’re useless now.

BTW., AnJaCo wins a bonus prize of five SV-POW! dollar for guessing that the specimen was “Sub-adult or juvenile. From the aforementioned disarticulated innominate, and from the dissociated epiphyses of the centra”. Logan was eighteen months old at death, which makes him a sub-adult as Bennett’s wallabies mature at 20-24 months.
