  • Happy 81st Thylacine Day: Thylacines were lucky to last as long as they did

    By Jack Ashby, on 7 September 2017

    81 years ago today – the 7th September 1936 – the last known thylacine died, committing its species, indeed its entire family, to extinction.

    It was locked out of the indoor section of its enclosure at a zoo in Hobart, and in the overnight chill of the Tasmanian winter it died of exposure. All that now remains of the then largest marsupial carnivore is in museums.

    In a sense it was lucky. (more…)

    Australia is widely considered to be the extinction capital of the world. In the 230 years since European invasion, 29 of its 315 native land mammals have been driven to extinction, and by far the majority of those that do currently survive have suffered significant (and in many cases almost total) declines – they are now only found in a fraction of their former habitats.

    This is all very depressing, but as I write this I am undertaking fieldwork in a remote area of central South Australia, volunteering for an organisation who are trying to make things better. This week’s Specimen of the Week is one of the species they protect. (more…)

    Specimen of the Week 283: The Eastern Quoll

    Mongooses, ferrets, shrews, meerkats, otters, weasels and cats: These are animals that most people will be familiar with.

    Planigales, ningauis, kalutas, dunnarts, mulgaras and quolls: Not so much.

    Despite all being small mammals, strangely named, absurdly cute (the second set even more so than the first), objectively interesting in many ecological, behavioural and evolutionary ways, there seems to be a difference in the level of attention between these groups of animal. The latter are all Australian marsupials, and for undoubtedly complicated political, colonial and egotistical reasons embedded in the western psyche, they don’t get their fair share of the limelight*. This week’s Specimen of the Week is a tiny step in addressing that, with…

    Eighty years extinct: today is Thylacine Day

    By Jack Ashby, on 7 September 2016

    80 years ago today, on the 7th September 1936, the last known thylacine died. With it, an entire branch of the tree of life was cut off.

    Thylacines, or Tasmanian tigers, were the last surviving member of a family of wolf-like marsupials that once hunted across all of Australia – the mainland as well as Tasmania. Regular readers of this blog (particularly these annual Thylacine Day posts, which we celebrate in the Grant Museum every year) will be familiar with the thylacine’s story, so I won’t go into detail here.

    A very deliberate extinction

    In short, thylacines were accused by Tasmania’s powerful farming lobby of predating sheep, and thereby damaging one of the island state’s principal economies. As a result, in 1830, they established a bounty scheme to encourage people to exterminate them. This policy was later adopted by the government, who (under pressure from the farmers) opted to pay for the bounty scheme themselves from 1888 to 1909. Inevitably over those decades the world’s (then) largest surviving marsupial carnivore’s numbers plummeted. (more…)

    The Rock Room is Getting a New Home

    By Nicholas J Booth, on 7 April 2016

    The Rock Room.

    The Rock Room.

    A Geology Museum has existed at UCL since 1855 (UCL was founded in 1826), 14 years after  the first professor of Geology, Thomas Webster, started at UCL. However geology has been collected for longer – the first recorded donation of geology specimens to UCL came in 1828 from a Mr. Davies Gilbert. Today the collection consists of over 100,000 specimens, from microfossils to large trace fossils, and ranging in age from c4.5 billion year old meteorites to relatively recent fossils (including my favourite fossil crab).

    The Rock Room has been in its present location since 1908, (more…)

    Specimen of the Week 223: The Tasmanian wolf

    By Paolo W Viscardi, on 18 January 2016

    One of the most interesting things about zoology for me is the way in which skulls are sculpted by evolutionary and environmental forces. A particularly fascinating outcome of such processes is convergent evolution, which occurs when distantly related organisms live in a similar environment and have a similar mode of life, resulting in them looking and often behaving like each other. My favourite example of this phenomenon is shown by my Specimen of the Week…

    It is perhaps no surprise that during December, most of the specimens featured in this blog tend to have associations with wintery Christmastime animals. There has been a reindeer, a polar bear, a robin, an owl and (last week) a partridge – all of which have been highlighted to kindle the yuletide cheer.

    In a radical departure, here’s a specimen that has absolutely no connection to winter, snow or any December seasonal holiday. But does it bring joy? Yes. This is an amazing specimen. Would this be a great Christmas present? Absolutely. If you ever see one, keep me in mind.

    Here it is – the one you’ve been waiting for – this week’s Specimen of the Week is the…

    Climbing up things can be challenging, be it hills, cliffs, trees or stairs. Climbing down, however is arguably far more difficult – your eyes are further from your hand-and foot-holds, your body is pointed in the wrong direction and gravity combines with momentum to pull you down faster than you’d like.

    Due* to the many drawbacks of climbing downwards, gliding has evolved many times in the animal kingdom – there are many species which have flaps of skin which form parachutes to slow their descent. Their names often contain the word “flying”, but true flight requires flapping wings. This post is not about flying lemurs, flying frogs, flying dragons, flying snakes, the four-winged dinosaur Microraptor, or even flying squirrels. This week’s Specimen of the Week is the far more accurately named… (more…)

    Happy 79th Thylacine Day: What they knew in 1896

    By Jack Ashby, on 7 September 2015

    79 years ago today , on the night of 7th of September 1936, the last known thylacine died of exposure, locked out of the indoor part of its enclosure in a Tasmanian zoo. This followed a government-sponsored cull based on pressure from the farming lobby, who incorrectly blamed the thylacine for the failure of the sheep industry. Happy Thylacine Day.

    Here at the Grant Museum, as holders of a significant collection of specimens, we like to commemorate Thylacine Day. Here you can read how we have commemorated previous Thylacine Days – including the story of their extinction, and how it’s being echoed today in the UK’s unscientific badger cull (which restarted last Friday).

    I recently bought book from 1894* – A Handbook to the Marsupialia and Monotremata – a species by species account of what was then known about those groups by Richard Lydekker. Lydekker was a significant figure at the Natural History Museum, London, and incidentally was born about 100m from us here at UCL. Here is what he had to say about thylacines: (more…)

    Specimen of the Week 200: The dodo

    200 weeks ago the Specimen of the Week was born, and here we are 198 specimens* later. For this auspicious occasion, I thought I should highlight one of the most important specimens in the Museum, both for historic reasons, and because it one of the things that visitors regularly ask about.

    Indeed, we know it is one of the most popular objects as it scores the highest in our “filth left on the glass by visitors scale”. We agree with our visitors’ assessment, and have included it in our Top Ten Objects trail.

    Possibly ranking as our most blogged about species, it’s about time that this week’s Specimen of the Week is… (more…)
