Friday mystery object #44

It’s been a busy week looking at cat skulls with Manabu Sakamoto from Bristol Uni. Lots of lovely pics which will hopefully eventually make their way on to the Horniman website once Rupert (our new Documentation Manager) works his magic with our database. Since cat skulls are pretty easy to identify I was a bit concerned that I might not find a sufficiently challenging mystery object for today, but fortunately Helen (our Collections Access Officer) and Nick (one of our awesome volunteers) came through with this (click for bigger):

So what is this object (easy) and more importantly, what is the head of it made from (tricky) and where does it come from (pretty easy once you get what it’s made from)?

Suggestions and questions below – I’ll do my best to answer in good time. Good luck!

On Friday I gave you this skull to identify:

I used this skull because the shape really appealed to me when I stumbled across it in one of my office drawers – here are another couple of views of the same specimen:

Most of you quickly worked out that this skull belongs to a rodent – and a big rodent at that.  The inflated nasal region was also quickly picked up by some of you and I think that’s what led Jonpaulkaiser to the correct answer first, followed by Neil who also managed a species level identification. Well done to everyone though, there were lots of very close attempts, with several of you missing out by a quill’s breadth – if you’ll excuse the frankly awful pun. This is of course (if you didn’t guess from the bad pun) a Continue reading

I am back at the Horniman this week, after last week’s soujourn to Plymouth. Yesterday I was working through some of the collections that I’ve been in the process of transferring from my office space to our stores building, when I came across this specimen:

I love the shape of this skull so much that I just had to have it as a mystery object. It would be too easy if I gave you a side-view, so you’ll just have to wait for that until Monday. Make your suggestions below and I’ll do my best to respond (although my home internet has been down for the past week, so I may be limited in how much opportunity I have to reply to questions).

Best of luck!

On Friday I was at the NatSCA conference, hosted by the Plymouth City Museum and Art Gallery. The conference was excellent (thanks Jan and Helen) and I really enjoyed the natural history collections on display – particularly this piece of partially made taxidermy:

I asked you to identify what species of bird this mannequin is intended to represent. The only actual bits of the bird are the legs, head and wings, so these are the bits you should have concentrated on.

I was a bit surprised that no-one managed to get this. Most people went down the line of thinking that it was a fairly long-legged and long-necked bird, but that is without taking into account that the feathers are missing! Feathers considerably alter the shape of a bird, smoothing the contours of the neck (which has a strong curvature in life which shortens it) and providing a substantial amount of insulation. Feathers also layer quite densely on top of one another, with a stiff rachis down the middle of each, which provides structural support, changing the outline.

In the end there was one person who came close – Neil, who correctly identified that it was a corvid of some description and his suggestion was supported by Bob O’H. It is in fact a Continue reading

This Friday the mystery object is coming to you from Plymouth where I am currently attending the Natural Science Collections Association conference. The natural history gallery here has some great material and I thought it might be nice to have one of the specimens as this week’s object. So do you have any idea what this partially stuffed bird is:

As usual you can put your suggestions in the comments section below – I will endeavour to answer any questions, although I may not have much opportunity whilst the conference is in full flow.

Hope you enjoy it!

On Friday I gave you this formidable looking object to identify:

Many  suggestions related to the saw-like appearance of this object, proposing either a human-made saw or the rostrum (nose) of a saw-fish (which are endangered cartilaginous fish of the genus Pristis). The closest answers all made reference to the articulation at the end of this object, which is the significant clue as to what this object is – the “teeth” are just secondary details.

Jake was the first to come close, followed by Kevin the epic and KateV, who gave a sensible mechanical breakdown of the likely use of this element. I’m not all that surprised to say that this week no-one worked out that the mystery object is a Continue reading

It’s hard to believe that it’s a year ago today that I started this blog – how time flies! The mystery object didn’t start until four months in and I strongly feel that it provides the backbone of the blog. So here is my forty-first mystery object – I hope you enjoy trying to work out what it is (whatever it might be, it looks pretty vicious):

As usual put your suggestions and questions below and I will do my best to answer (without giving it away). The answer will be posted on Monday.

Good luck!

On Friday I gave you this skeleton to identify:

It looks a bit like a snake, but there are a couple of give-aways that mean it must be something else. First of all, snakes may look like they’re all tail, but actually they have quite short tails in relation to their body length (hint – the tail starts just after the ribs end) and second, a snake’s skull has a very open light structure (as I’ve discussed before). Both of these snaky features can be seen in this image taken by dbking:

Viperid snake skeleton (image by dbking)

Viperid snake skeleton (image by dbking)

So, if it’s not a snake, what is it? There are quite a few animals that have a long slim body with no limbs, from eels to caecilians to a variety of lizards (including, but not restricted to snakes, which are a discrete subgroup within the lizards). However, this is not an eel because their ribs don’t form a cage – they form vertical projections for their muscles to work against, it’s not a caecilian because they have even shorter tails than snakes, which leaves us with the non-snaky legless lizards (as recognised by Gimpy).

Legless lizards crop up in at least three major groups of lizard (not counting snakes) so there is a fair amount of choice out there. The Amphisbaenia are really weird and the mystery object doesn’t have the right skull shape to be one of them. The Pygopodidae are legless members of the same group as the geckos – and the mystery object could probably be one of them, except it’s not. It is in fact a member of the Anguoidea (more particularly the Anguidae) and it was identified correctly by Jim (and seconded by Neil) as being a  Continue reading

Last week’s object was totally unrelated to natural history, but this week I am returning to my area of interest. Any idea what this might be:

(Length across specimen approx 45cm)

It’s a bit of an easy one, but next week I’ll make up for it with something a more difficult.

As usual you can ask questions or make your suggestions in the comments section below – I’ll do my best to answer, but I won’t be in the office for most of the day, so I can’t guarantee a rapid response. Good luck!

Ask A Biologist

I’ve been involved with Ask A Biologist (affectionately known as AAB) for quite a while now, so I am excited that the site is being relaunched today with a substantial make-over that should make it easier for everybody to use (you may notice that I’ve given my blog a make-over as well). The site was started by my buddy Dave Hone of Archosaur Musings fame and I feel fortunate to have been a part of it since its first tenuous steps.

AAB is a fantastic free resource that provides a direct line to researchers in the field of biology, palaeontology, medicine and other associated biosciences. We have fielded all kinds of questions, from Do Crocodiles play around to  Functional heterologous complementation. The site is intended to give authoritative answers whenever possible and informed opinions where answers are simply not available. This reflects the true nature of science, where the answer “I don’t know” is sometimes the most honest answer; one that can usually followed by a suggestion based on what is known. These are often the most interesting answers, because they lead to discussion and sometimes full debate – something that stimulates the development and testing of ideas (Dromaeosaur claws is a great example).

The public is composed of a huge variety of people with diverse backgrounds and very different experiences. This means that the contributors to the site are often faced with questions phrased in terms that they have not encountered before; it’s amazing how helpful this fresh perspective can be when you’re totally immersed in an area of study. If you are involved in bioscience at a professional level and you want to engage more fully with the public I would strongly recommend getting involved with AAB – it’s voluntary, but the rewards are substantial. For those of you who are not professional biology types, but you have questions about something to do with biology, I would recommend searching the archives of AAB and if you can’t find the answer there, then go  ahead and Ask A Biologist.

On Friday I deviated from my usual natural history theme when I gave you this object:

There were a host of suggestions, from a tea caddy to part of the Large Hadron Collider, however, one person managed to identify that this is actually a pin cushion – here it is folded out in all its glory:

So well done to KateV (who is also known as mum by me)!

This particular pincushion is European and made of cardboard and fabric – I would tell you more, but out database doesn’t seem to be responding this morning, so any additional information will have to follow once that’s up and running, since I am a total ignoramus about such cultural items. Hopefully more to follow…

Friday’s object was this exploded skull:
I identified it as a hedgehog, Erinaceus europaeus Linnaeus, 1758 based on comparison with the skull (particularly the lower jaw) of a specimen that I had as a mystery object last August:

My guess is that the specimen was probably a fairly young adult, since most of the fragmentation of the skull is along suture lines. However, the disarticulation is greater than would be expected simply from a poorly fused specimen, so it looks like damage has also been sustained. Since the delicate nasal turbinates are still intact and in place, I expect the damage probably happened when they were still protected by soft tissue – making me suspect that it happened before the animal was skeletonised. Given the susceptibility of hedgehogs to getting run over, I expect that this individual was killed on the road by a glancing blow to the head that loosened teeth and sutures. I’m pleased to say that Jake agreed with my identification and cause of death for this specimen, so a hearty congratulations to him!

This week I am going to give you a genuine mystery object – something from the collections of the museum that has no identification. I have been dealing with a few of these sorts of things recently whilst organising the osteological (that’s bone) store.

Often specimens have been acquired in a big batch, which invariably means that there will be a box left at the end which contains the jumbled and broken bits and pieces that have lost information or have been separated from the rest of a specimen during the move from their old home, or at sometime in the distant past.

Here’s one such specimen:

Do you have any idea what this exploded skull might belong to – and why it might be exploded?

As usual post your suggestions below. I might not be able to answer any questions this week, because I’m off to Norway to visit a good friend I don’t see often enough in Trondheim. Who knows, next week I may have a Norwegian mystery object for you to identify… Good luck!

Friday mystery object #37 answer

On Good Friday I provided a series of eggs in a mystery Easter egg hunt. I will list the answers at the end of this post with a reference to the people who made a correct identification, but first I want to discuss the issue of eggs.

I had reservations about putting together last Friday’s post, because eggs are a delicate subject matter – and by that I don’t mean I was concerned about possible damage to the eggs (I’m trained to deal with such things after all), I mean that the issue of eggs is ethically and legally delicate. I checked the Wildlife and Countryside Act  1981 and associated legislation to ensure that both myself and the Museum were on legally firm ground with respect to the eggs and I am now fulfilling the ethical requirement (as I perceive it) by attempting to clarify the position on collecting, keeping and trading bird eggs in England and Wales (slightly different rules apply in Scotland).

Collecting wild bird eggs is illegal. It makes no difference if the bird is a golden eagle or a wood pigeon.

Selling wild bird eggs is illegal. As one auctioneer found to his cost recently.

It is illegal to possess bird eggs unless you can prove they were obtained legally. This means that you need evidence that the eggs were collected prior to The Protection of Birds Act 1954 – and of course evidence means documentation.

Egg collecting used to be a common hobby, usually associated with young lads. Unfortunately collecting can be quite addictive and when someone of a collecting mindset wants to fill holes in their collection they will sometimes go to extraordinary lengths to do it – breaking the Law included. This means that there are still quite a few people out there who collect and deal in eggs – something that has to be taken seriously. It needs to be taken seriously because collectors tend to target those eggs that are rare – precisely the ones that are needed for rare bird populations to survive and recover.

Museums have a bit of a hard time with people offering egg collections. Often when someone passes away their family will find a shoebox of eggs in the loft that was collected when the deceased was a child. Usually, such collections were collected prior to 1954, but they lack any documentation. This means that the family is left holding an illegal egg collection that they are keen to get rid of, but which they don’t want to destroy – so they offer it to museums. Of course, museums are bound by the Law, so they too can be prosecuted for holding egg collections that cannot be proved to pre-date 1954. This means that museums will turn away egg collections that lack proper documentation and associated data – and the best course of action is probably for the families to contact DEFRA for advice (they’re very approachable and they aren’t looking for unwitting innocents to prosecute). The advice I would give is that if the collection has no documentation and associated data (like species names, place collected and all-importantly date of collection) it is probably best to dispose of the eggs. If it does have data and documentation then a museum may be willing to take it as a donation – but bear in mind that most museums are very wary of egg collections and don’t be surprised if they decline your offer.

Since it’s Easter I’ve decided to make the Good Friday mystery object a bit more of an Easter egg hunt, so expect a posts during the day every few hours with new eggs for you to identify. So what about this:

I will try to answer questions requesting clarification about an aspect of the natural history of the animal that produced the various eggs, but I won’t let on if the answers are correct. I hope you enjoy this slight twist on my usual format!
