Friday mystery object #57 answer

On Friday I gave you a specimen that I had to identify myself earlier in the week:

The first steps of this identification are quite straight-forward – in the words of Jake it “Looks a bit sheepy and a bit deery” which pins this firmly in the order BovidaeDave Godfrey neatly summarised what makes it look sheepy and deery – “Diastema, lack of upper incisors, and the shape of the teeth“. Rob went a step further and ruled out deer, sheep, goats and camelids – coming to the conclusion that this is an African bovid of some kind. Then David Craven blasted through the narrowing-down process and hit upon the same species as I had concluded it was, namely a Bush or Common Duiker Sylvicapra grimmia Ogilby, 1837.

I must admit that I think this could also possibly be an Ader’s Duiker Cephalophus adersi Thomas, 1918 but the size and the shape of the forehead preclude it being any other Duiker that I can think of. I will admit to relying on the excellent Mammals of Tanzania skull key by the Field Museum to help with my identification – plus access to other Duikers in the collections at the Horniman – which is how I worked out it wasn’t one of the Duiker’s suggested by Raymond Ho (who came so very close).

This Friday I may present another species from box NH.83.1 – but let’s see what my week holds in store, in case there’s something else that catches my eye…

  1. Didn’t know The Mammals of Tanzania site, that’s an excellent resource. Even if you are not looking at a mammal from that area, it’s good to see a step-by-step on some of the diagnostic features you may want to think about in any ID.
