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 →

This week I have some mystery objects that I had to identify earlier this week. Any idea what these things might be?

I’m going to be in Buxton for the day, looking at a mermaid (as is my wont), so I may not be able to respond to comments as usual. That said, I will try, so put your suggestions, observations and questions below – I will respond eventually.

Good luck!

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 →

This week’s mystery object is one that seems to perplex a lot of members of the public when they come across it, so I thought it might be a good test of your identification skills:

Any idea what this bone is and what it belonged to? You can put your suggestions, comments and questions below and I’ll try to respond during the day. Good luck!

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 →

This week I’m giving you a mystery object that I think will be fairly straightforward to identify, although it might take a few attempts to get the right species:

Let me know what you think in the comments box below – I’ll do my best to reply to any questions. Good luck!

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 →
