Friday mystery object #307

The last few months have been particularly busy for me as I’ve been working on a lighting project in the Irish Room of the Dead Zoo in Dublin, so I’ve not had much opportunity to dig out mystery objects and get good images for you to identify.

However, I have moved pretty much every specimen in the gallery and if you want to see how much stuff that entails there’s a 3D interactive map of the space available here (if you want to have a virtual tour of the whole museum check this out). All this moving means I’ve seen a lot of specimens, so here’s one of them for you to have a go at identifying:

For a some of you this will be way too easy, so let’s have your best cryptic clues, hints and riddles as to what this is.

Have fun!

Friday mystery object #305 answer

Last week I gave you this specimen to identify, with a clue about the tail being distinctive:

mystery305bmystery305d

There were lots of correct answers – the first coming from palfreyman1414 who nailed it with this great cryptic clue relating to its scientific name:

It is indeed Potus flavus (Schreber, 1774) or as Allen Hazen and jennifermacaire hinted at with kinky clues, a Kinkajou. They’re also known as Sun Bears, Lirón (which is also the Spanish name for the Dormouse) or Micoleón (lion monkeys).

As the name Micoleón suggests, these South American floofsters are what happens when a carnivore tries to be a monkey. They have dexterous digits for climbing and handling the fruit that makes up the bulk of their diet and they are one of only two carnivores with a prehensile tail (the other is the Binturong) – hence that tail clue.

This tail acts like a fifth limb that helps the Kinkajou climb and in particular it allows the animal to hang down in order to reach fruit at the ends of slender branches:

Unlike monkeys, the Kinkajou is nocturnal, relying on its sense of smell and touch more than its eyesight to work out which fruit is ripe. It uses its very long tongue to scoop out fruit pulp and sometimes to feed on nectar from flowers.

All in all it’s a very curious little carnivore that looks more like a lemur than it does its closest cousin, the Coatimundis.

This week I was worried that I didn’t have a mystery object planned, but then I stumbled across this on my phone:

It’s probably a bit too easy for some of you, so I’d encourage using some cryptic clues and hints to say what it is in the comments box below.

I’ve had a problem with spam comments recently and have switched on a filter to ensure that people’s first posts are approved (regular posters shouldn’t be affected) – fear not, I will be keeping an eye on it and approving first timers!

Friday mystery object #303 answer

Last week I gave you this mysterious bit of bone from the Thames to have a go at identifying:

mystery303b

A few ideas were put forward, but DrewM was spot on with the suggestion:

I think it’s the synsacrum of a bird, without the ilia fused – the foramina are for spinal nerves.

A synsacrum is a fused section of vertebrae including the sacrum (which is where the pelvis attaches to the spine). General opinion quickly agreed with that suggestion, but the taxonomic group that the synsacrum belongs to remained unguessed.

That is perhaps unsurprising, since it’s hard to find good comparative images of bird synsacra, especially with the hips and lateral (or side) bits knocked off and worn down.

I had a go at looking through some of the comparative bird osteology collections at the Dead Zoo to get a feel for birds with a similar synsacral morphology.

The usual suspect for a bird bone found in the Thames (for me at least) is Chicken, since they’re so closely associated with humans and a lot of the bones washed up on the banks of the Thames are from butchery and food waste. The size was about right, but the vertebral centra (the middle bits) of the Chicken synsacrum become more narrow in the hip-line than in the mystery specimen.

Next I looked at ducks, whose centra taper more in the direction of the tail, then grebes whose whole synsacrum is more narrow overall:

Eventually I made it to the gulls who seem to be a much better fit in terms of shape and the Herring Gull Larus argentatus Pontoppidan, 1763 was a good fit for size:

Herring Gull synsacrum

Now this doesn’t mean to say that the mystery object is certainly from a Herring Gull. I would want to have the object in my hand and comparative material available from several specimens to check the identification before being sure, but on the basis of the images that Keith Dunmall kindly provided, I think we’re in the right ball park.

More mysteries next week!

Friday mystery object #299

This week I’ve decided to give you a mystery object that has its skin and fur, so in theory it should be really easy to work out what it is. In theory.

Any idea what species this adorable little critter belongs to?

As usual you can put your thoughts, questions and suggestions in the comments section below. If you find this too easy then maybe you can try to find a cleverly cryptic way to let me know.

Have fun!

Friday mystery object #298

This week it’s back to bones. I’ve had a couple of very helpful work experience students photographing some specimens from the Dead Zoo comparative osteology collection and here’s a distinctive bone for you to identify. The Order should be easy, the Family simple enough, but the Genus and Species may prove more difficult:

So if you think you know what this is please put your suggestions in the comments below. Have fun!
