Friday mystery object #270 answer


Last week I gave you a tricky object from the Grant Museum of Zoology to identify:

mystery270

While obviously a carnivore of some sort – that much is clear from the canines and shape of the upper fourth premolar – it’s one of a type that has a large number of species and is generally not very familiar to most people.

However, despite being tricky, consensus in the comments moved towards the right family; the Viverridae. Then palfreyman1414 narrowed it down to the correct genus – Genetta.

Unfortunately, it was difficult to identify to species level, partly because it’s missing its auditory bullae (the rounded structures on the underside of a mammal skull that house the bones of the ear). These bullae are useful in distinguishing between the different species in this genus, of which there are many. I can’t say exactly how many, as the number of properly recognised species varies, partly due to hybridisation, but there are about 17.

Nevertheless, palfreyman1414 provided a link to a very useful resource that, with a bit of digging, provided a table of skull and tooth characters (amongst others) for identification of Genets.

Working through the visible characters described in this matrix, removing species that didn’t correspond with the mystery specimen, I was left with just the Abyssinian Genet Genetta abyssinica (Rüppel, 1836).

So many thanks to everyone (but particularly palfreyman1414) for all your help in solving this mystery – without your help I would probably have been stuck at a genus level identification for this specimen, when now I have a pretty robust species identification.

More again next week!

  1. Wow! I did a science! I am so overwhelmed (particularly after a thirteen hour day at work with the necessity of anther four to six hours tomorrow, dagnabbit) that I am going to take my Oscar and pawn it for some booze.

    “Right now you like me! You really like me!”

    • Must add that Joe Vans and Allen Hazen were just as, to my mind, diligent and helpful as me. I would never have got onto this track without their inputs. And they clearly know a heck of a lot more about this stuff than I do.

      Also, really glad if we all genuinely helped with your identification of the species of this specimen. It’s almost as though we have laid down a marker (albeit so slight as to be almost imperceptible) in the recorded history (if that’s not a redundancy) of life…
