In June this year the Natural Sciences Department received a rather special donation from the Royal Botanic Gardens, Kew; a life size model of a giant millipede, Arthropleura, that would have lived in the Carboniferous Period, 300 million years ago. Arthropleura is the largest invertebrate (creepy-crawly) ever known to have lived on land, reaching up to 2.6 metres in length, but despite its monstrous proportions it is thought to have been a harmless herbivore.

The model was originally on display in Kew Garden’s Evolution House but when the space was dismantled in preparation for the HLF funded restoration of the Temperate House, it was no longer needed. So it was donated to Amgueddfa Cymru – National Museum Wales, thanks to the generosity of Chris Mills, David Cook and Jonathan Farley at Kew.

The Arthropleura model was in need of some substantial conservation work when it arrived at AC-NMC. It had been on open display for many years in a glass house alongside living plants and was damaged and rusty. The humid display environment had caused the surface paint to flake away and several spiders and snails had taken up residence on the underside of the model!

The first job was to give the model a good wash with hot soapy water and remove the dirt and cobwebs! Then all the flaking paint was scrubbed off, the damaged areas on the legs and head were rebuilt with an epoxy putty and the surface textures recreated. The nuts and bolts of the removable antennae had rusted together, so the metal parts were replaced with new stainless steel threaded rods.

Once the repairs were complete the model was carefully painted with acrylics and then coated in a durable varnish, making it once again suitable for public display.

Some of the Natural Science staff had become rather attached to the impressive 1.5m long millipede model whilst it underwent conservation work in the lab and named it Arthur the Arthropleura! We also decided to have a bit of Halloween fun with Arthur… so he “escaped” and went on the run around the museum galleries! We posted pictures of his adventures on the @CardiffCurator Natural Sciences Twitter account and had a fantastic response from our followers. Arthur the Arthropleura is now a social media star and is a really wonderful addition to our collections!         

Hello bulb buddies!

I hope you’re all having fun looking after your bulbs.

Autumn has finally arrived in Cardiff. There is a chill in the air and the leaves on the trees are turning lovely shades of orange, yellow and brown.

Autumn has arrived late this year. October’s weather was warmer and wetter than average and this meant lots of the trees kept their green leaves for longer than usual.

The weather on Halloween was extra-special! Temperatures in some areas of the UK, such as south England and north Wales, reached well over 20°C. 

The temperature in Kew Gardens in west London reached a whopping 23.6°C, which is the highest temperature ever recorded in the UK on Halloween. I hope you didn’t get too hot in your spooky costumes!

I think these weird weather conditions are very interesting and am excited to see what strange things you find during your spring bulb experiments.

Has autumn arrived where you live? Are the leaves changing colour and falling from the trees? Why don’t you take an autumnal picture and send it to me in an email? I might even post it here on my blog.

Remember that you should now have started recording the temperature and rainfall on your weather charts. If you can’t remember what you’re supposed to do you can look at the Keeping Weather Records page on my website.

Many Thanks

A planting day of bulbous proportions!

Eleven thousand and three hundred bulbs were planted by school scientists across the UK to kick start the Spring Bulbs for Schools investigation. Seven and a half thousand pupils from one hundred and seventy nine schools got planting to investigate climate change.

Here is a map to show you where the bulbs were planted.

Here are some of the pictures they sent in. Follow their progress and the questions they raise as they record the local weather and flowering through the winter and into the spring.

‘From ghoulies and ghosties, and long-leggedy beasties, and things that go bump in the night…’

Last Friday, Natural Sciences staff celebrated Halloween in grand style with a host of truly ghoulish and grizzly specimens out in the main hall at National Museum Cardiff. The National Herbarium was transformed into a ghoul filled graveyard, and a large mosquito model leered down from the entomology (insects) stand, any moment threatening to jump on the jugular of an unsuspecting member of the public. Younger visitors to the OPAL stand were encouraged to stealthily walk through a spider’s web without disturbing its occupant, and learn about glow in the dark scorpions. Meanwhile the biggest creepy crawly that ever lived, Arthropleura, a 300 million year old extinct giant millipede, escaped from the Palaeontology (fossil) stand and went off to explore the Impressionist galleries.

Despite all of the fun, visitors gained an insight about some of the 6 million specimens that are held behind the scenes at the museum, and the incredible work of the staff that care for them.  From bats to giant squid, volcanic rocks to fungi, we covered them all. One of my favourite parts of the day was taking visitors behind the scenes on tours of the Entomology and Molluscan sections to see insects and shells and the Spirit store (not ghosts, but where we keep our specimens preserved in fluid such as sea worms and crabs). It is such a rewarding experience to see the excitement of people visiting the collections for the first time, and proudly talking about all of the great research work that we do.

If you missed it, don’t worry! We have a whole host of open days and curator led sessions coming up. See our What’s Onto find out more!

Museum scientists were out and about during half-term week, when the I Spy…Nature pop-up museum paid a visit to Fairwater Library on 30th October.  Curators from the Botany, Invertebrate Diversity and Palaeontology sections took along specimens from their collection areas to show the public, along with a microscope and quizzes to encourage them to look even closer.

Ingrid Jüttner challenged people to identify as many trees as they could, using beautiful displays of freshly-pressed leaves and fruits.  This activity was a big hit with grown-ups, and it was very pleasing to see so many parents and grandparents encouraging children to learn more about these important plants, which bring our living spaces to life.

The library’s meeting room became temporary home to an impressive array of marine and mollusc specimens from the Invertebrate Diversity section.  People were fascinated by the creatures on display, which evoked a range of reactions (including ‘they’re really gross!’) depending on how they felt about slugs and worms!  Teresa Darbyshire showed some of the diversity of life found around our shores, with beautiful sea shells, lobster, starfish, and a pickled octopus and giant sea worm.  Visitors tried their hands at identifying shells using a key, all good training for trips to the beach!  Ben Rowson challenged people to identify mystery objects under the microscope, and introduced them to slug identification using his recently published book and life-like models.

Lucy McCobb showed visitors a range of fossils from different periods of the Earth’s history, ranging from an Ice Age mastodon tooth and horse’s leg bone, through Jurassic ammonites and ichthyosaur bones, to trilobites, which are among Wales’s oldest fossils.  The ‘what’s in a name?’ quiz was popular with children, and asked them to use the meanings of scientific names to match up the name with the correct fossil.

This was I Spy..Nature's  first venture into libraries, and showed that they have great potential as venues for taking the Museum’s collections and experts out into communities.
