I thought it might prove quite tricky, yet several of you managed to work out what it was and which animal it came from.
Jake spotted that it was from a young animal – as you can see from the unfused ends of the bone. He also noticed that it was a bit of a strange shape, a bit like a tibia, but actually a radius.
Barbara Powell suggested that it belonged to an animal built for power rather than speed and henstridgesj suggested one such critter – the Aardvark. Although that wasn’t right, or even close in terms of evolutionary relationships, it was very close from the perspective of functional adaptations.
After that it was a short step to the same answer that I decided on when I had to identify this piece of bone. Barabara Powell, henstridgesj and Steven D. Garber, PhD all converged on the answer of Continue reading →
This Friday I’ve decided to really challenge your identification skills with a single bone that I found in the Horniman’s collections.
There was no information of any kind with this specimen, although the material it shared a box with was acquired from the King’s College Comparative Zoology collection. That means that it could be from pretty much any animal on the planet. What do you think it is? (N.B. since it is tricky I’ve given you an image from every angle.)
As usual, you can put your questions, comments and suggestions below and I’ll do my best to respond during the day. Good luck (I think you may need it).
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I chose this partly because it’s a great mount and partly because I needed to check the identification, which was out of date.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’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 →
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 →
I know Christmas has been and gone, so this post is far from breaking news, but I’ve been meaning to write it ever since I saw this advertisement on a local bus stop:
Now although I’m an atheist, I really don’t have a problem with the advertisement for any reason beyond the utter banality of the message. It’s a bit like saying this:
For both there is an etymological root linking a supernatural figure to the name of a day – it’s very common, just think of other supernatural figures that lend their names to days, like Tiw, Wodin and Freyja. I wonder if we should also remember these deities on their appropriate days? That seems to be the logical implication of the Christian advert.
But then, what should be done about Easter? Maintaining the logic of the Christian advertising around Christmas, it would seem that we should remember that Easter is named for the pagan goddess Ēostre. This seems doubly reasonable since there is hardly any difference between the Christian celebration and the Pagan fertility festival, with all it’s rampant rabbits and eggy delights.
The fact is that by following the logic of the advertising we should either be utterly ignoring the etymological root of Christmas, as we do for Easter and Tuesday, or we should be acknowledging the etymological root for all days named after supernatural beings.
I’ve decided to make sure I remember that Christmas is about Christ, Easter is about Ēostre and Thursday is most definitely about Thor, which is presumably what constitutes hammer time:
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.
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 →
This week I have something from the Horniman’s collections that some of you will probably be able to identify straight away, whilst others may have a slightly harder time:
Any idea what it is?
Put your suggestions, comments and questions below and I’ll do my best to respond. Good luck!
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!
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 →
The WordPress.com stats helper monkeys prepared a 2011 annual report for this blog.
Here’s an excerpt:
The concert hall at the Syndey Opera House holds 2,700 people. This blog was viewed about 48,000 times in 2011. If it were a concert at Sydney Opera House, it would take about 18 sold-out performances for that many people to see it.
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!
