Friday mystery object #134 answer

On Friday I gave you a very nice specimen from the Horniman Museum to identify:

I chose this partly because it’s a great mount and partly because I needed to check the identification, which was out of date.

You all did a great job of breaking down the various options – and there were a few. Jake made the comment:

Is it dippy or a bit ruff ?

This I took as a question about whether the specimen was a Kangaroo Rat (of the genus Dipodomys) or a Rufous Rat-kangaroo (Aepyprymnus rufescens). There was another interpretation that fit with the dippy clue – the correct Family name, which is Dipodidae.

Barbara Powell and Jamie Revell were in the right area and henstridgesj suggested J.j. which was pretty much there, assuming he meant Jaculus jaculus. It is in fact the skeleton of the  Continue reading →

Friday mystery object #133 answer

Friday’s mystery object was meant to be a bit of a challenge:

Post-cranial bones can be tricky to identify, especially if you don’t have much comparative material available.

The first challenge was to work out which bits of bone are present – something that Rhea and Jake managed very well. This particular specimen is composed of a broken portion of right mandible (showing the coronoid process, condyloid process and angular process), the left ilium, and the first three cervical vertebrae (which include the axis and atlas bones).

Identifying the species was a bit more tricky using just these few bits of bone, but several of you managed to get there. Henstridgesj was the first to suggest  Continue reading →

On Friday I gave you these objects to identify:

I expected you to work out what these came from pretty easily – and you proved me right. In fact, I think this was probably the easiest mystery object so far, given that everyone managed to get a correct identification of  Continue reading →

Friday mystery object #131 answer

On Friday I showed you some specimens that I had to identify in the museum last week, and I asked if you had any idea what they might be:

Perhaps unsurprisingly, several of you did have a very good idea.

They look a bit bony, but they’re not bone. They look a bit toothy, but they’re not teeth. They look a scutey, but they’re not scutes. They are in fact from an animal that doesn’t have bones, teeth or scutes.

Denis Copilas, Matt king, henstridgesj, Barbara Powell and David all managed to spot that these are the hooks from a very large  Continue reading →

Friday mystery object #130 answer

On Friday I gave you this specimen to identify:

I thought that some of you might find it a bit tricky, since this is a shell from a group of animals that aren’t that familiar to most people.

Barbara Powell was the first to spot what this shell came from and her identification was supported by Dave Godfrey, Julie Doyle and henstridgesj. It’s a   Continue reading →

Friday mystery object #129 answer

On Friday I gave you this object to identify:

This type of bone can prove tricky to identify, and we often have queries about them on Ask A Biologist. With a large example like this one there will often be a suspicion that it comes from a human. 

However, this is in fact the humerus of a bird – the large flange at the proximal end (the bit nearest the body) makes it hard to spot the rounded point where it articulates with the scapula, coracoid and furcula bones that make up the shoulder joint. The flange itself provides a large attachment area for the tendons and muscle needed to power and control flight.

Here are some images of a (much smaller) goose humerus that show the general structure of the bone more clearly:

Once you’ve recognised the mystery object as the humerus of a bird, the length of about 45cm (17.7 inches) immediately narrows down the species it could come from.

Jack Ashby was the first to recognise what this humerus belonged to and he found support from Rachel, Carlos, Julie Doyle and initially Barbara Powell (although she later opted for another possibility). It’s the humerus of an   Continue reading →

Friday mystery object #128 answer

Happy New Year!

On Friday I gave you this piece of an animal to identify:

As expected, you managed to work out what it is in fairly short order.

Jake recognised it as skin, Denis Copilas as scales and Rhea as carapace – all of which are right at least in part. Henstridgesj and Barbara Powell’s friend Alison spotted that the section of carapace came from a Cowfish or Boxfish. There wasn’t really enough information available to identify it any further than that.

Fortunately this specimen had a label associated with it, so I can tell you that the section of carapace is from the  Continue reading →

Friday mystery object #127 answer

Apologies for a somewhat belated answer to last week’s mystery object – Christmas and all that…

I gave you these two unidentified objects from the Horniman Museum collections, so you could have a go at identifying them:

I was not disappointed either – Jake recognised that they were upper molars or premolars from a grazing animal and Rhea identified the animal in this cryptic clue:

If the owner of these teeth could market and sell a coffee, would it be interested in a label with a *unicorn* mascot that comes in the sumatran or javan blends? Continue reading →

Friday mystery object #126 answer

On Friday I gave you a bit of a tricky mystery object in the shape of this partial skull:

I wasn’t expecting anyone to get it without some clues, but I underestimated my talented audience!

Jake spotted that it was a mammal based on the ear morphology and then worked out what kind of animal based on clues from henstridgesj who suggested seal and Julie Doyle, who managed to not only identify the species, but drop this lovely cryptic clue to convey that information:

Not a lot to phocus on, but……. I’m harboring an idea about who it might be. Continue reading →

Friday mystery object #125 answer

On Friday I gave you a bit of a tricky mystery object:

Jackashby spotted that the skull is from a bat and Rob Hinkley did a bit of research while on a trip to the Horniman and was able to identify what the specimen is labelled as. Apparently it’s a  Continue reading →

Friday mystery object #123 answer

On Friday I gave you a genuine mystery object from the Horniman’s collections:

It had been highlighted as potentially being human in origin, but it’s very short, despite being fully fused (therefore from an adult) and the condyles (the bumps that make the top of the knee) are too similar in size – humans have a bigger condyle on the inside of the knee.

However, the general shape is quite similar to a human femur – the depth and orientation of the condyles and the groove between them is all wrong for a quadrupedal animal and the femoral head and neck (the articulation at the top that goes into the hip) are at an angle and shape similar to that seem in humans.

There were some great observations and suggestions and I was pleased that henstridgesj managed to get the same identification as I finally decided on, with Matt King making a very similar suggestion. I think it’s the femur of a  Continue reading →

Friday mystery object #122 answer

On Friday I gave you this object to identify:

As I suspected, everyone spotted that this skull belonged to a member of the Cat family (the Felidae). However, cats are very conservative (as Julie Doyle pointed out) – their skulls all tend to look much the same, which made it hard to identify the species.

This skull is even trickier to identify than it might have been because it comes from a young animal, so it hasn’t reached the full size or development that you might expect from an adult.

Nonetheless, several of you suggested cats from the same genus and henstridgesj worked out that it was between two species. It is in fact the skull of a  Continue reading →

Friday mystery object #121 answer

Apologies for the late posting and brevity of the FMO answer today, I’m not feeling at all well.

On Friday I gave you something a bit more ‘taxing’ than the previous week’s mystery object:

Some of you spotted the clue hidden in my statement and Bubba, Carlos, Will, Neil, henstidgesj and Julie Doyle all implied or identified that this as the skull of Continue reading →

Friday mystery object #120 answer

As promised, last Friday’s mystery object turned out to be easy:

The very first reply by Gerry gave the correct species and every subsequent suggestion was for the same animal.

With those huge razor-like incisors and canines what could this be other than a  Continue reading →

Friday mystery object #119 answer

On Friday I gave you this object to identify:

I asked you what this is, what it’s for, how it works and where it’s from – no easy task based on the limited information available from the photo.

Nonetheless, through a process of group deduction you worked out that it’s a copper container that holds water and produces steam and it’s from Tibet. Pretty good going. The one thing that nobody got was the purpose of this object.

Friday mystery object #118 answer

On Friday I gave you this complete skeleton to identify:

As I expected, you managed to identify it in no time, with excellent use of hints and clues to get the answer across without spoiling the fun.

John the Hutch was the first to get it right (and was in fact the first to respond) with Carlos, henstridgesj, Jake, Henry Gee and Julie Doyle also recognising that this was the skeleton of a  Continue reading →

Friday mystery object #116 answer

On Friday I gave you this skull to identify:

Jake spotted that this was a marsupial’s skull straight away and many of you suggested Kangaroo using a variety of crafty clues. There was also a well reasoned suggestion of Koala that fell just a little short.

Obenedo missed the correct answer by a hair(y nose) but got the right type of animal, as did jonpaulkaiser, Matt King, Jake and Cromercrox.

Neil managed to go that little bit further and get the right species –  Continue reading →

Friday mystery object #113 answer

On Friday I gave you this object to identify:

Rather unusually no-one managed to identify it. It’s not native to the UK and looks similar to quite a large variety of other species, because it’s a member of the Passeriformes (the perching birds), which is a hugely diverse and numerous group of birds. These factors make identifying the bird tricky, but without the plumage there to provide clues it was a very difficult task.

The plumage would have been a big help here, since the name of this bird is taken largely from a description of the plumage.

As you can probably work out from the photo above, it’s a Long-tailed Glossy Starling Lamprotornis caudatus (Statius Muller, 1776).

These tropical African birds are similar in diet and habits to the European Starling that we see more commonly – they just look a lot prettier.

 

Friday mystery object #111 answer

On Friday I gave you this object (from the NHM) to identify:

It was a bit of a tricky one for those of you who haven’t seen the First Time Out exhibition (jackashby and David Godfrey obviously did see it). This fossil skull looks like it belonged to some kind of pig rather than a primate – yes, that’s right, I said primate.

The main feature visible here that indicates that this skull may belong to a primate is the enclosed orbit, which isn’t a particularly strong characteristic since various ungulates also have an enclosed orbit – as I said, it’s a tricky one.

The type of primate is the Koala Lemur Megaladapis edwardsi Forsyth Major, 1894 from Madagascar. It was an arboreal, slow moving, gorilla-sized folivore – with superficial similarities to Koalas (hence the name). It is hypothesised that the extended bony nasal region may have supported a prehensile top lip, that would have been beneficial when foraging for leaves in the trees.

I won’t go into much detail here, because other curators have provided their interpretation for this object as part of the First Time Out project, so I will leave you with a link to that information. However, I would be interested in taking a closer look at the dentition and complete skeleton of one of these animals – I’d like to get a better grip on this apparent convergence on a suid cranial morphology and more gorilla-like body. I wonder what it might have looked like?
