For the last two years we have put together an advent calendar celebrating some of the beautiful specimens in our natural history collections at National Museum Cardiff. We have been tweeting these from the @CardiffCurator Twitter account each day and will continue throughout December. The specimens behind the first twelve doors have been inspired by the song ‘Twelve Days of Christmas’.

We have compiled a Storify story on our advent calendar, which can be viewed here.

Two weeks ago, Botany Curators at Amgueddfa Cymru-National Museum Cardiff welcomed scientists from across Europe, including Romania, Bulgaria, Germany and Spain. The visitors, who are all experts in the study of plant fossils and pollen analysis, spent two days discussing how best to study the changes that have occurred in plant diversity over the last 400 million years. These changes are important as they help scientists understand how vegetation has influenced climate and environmental change in the past.  The meeting included 17 presentations discussing the vegetation from different geological time periods. The visitors also had the opportunity to go behind-the-scenes at National Museum Cardiff to see a selection of rare plant fossils from the David Davies Collection and pollen specimens from the Hyde Collection.  This meeting was fully funded by an exclusive grant from the European Science Foundation. It is intended that the workshop will inspire a series of international collaborative projects that will maintain the Museum’s reputation as a centre of excellence in this field.

We produced a Storify Story based on Tweets made throughout the conference.

Every Monday curatorial staff from the Department of Natural Sciences at Amgueddfa Cymru - National Museum Wales highlight some of the fantastic mollusc specimens from our collections, on Twitter using the hashtag #MolluscMonday

The Molluscan collections at Amgueddfa Cymru — National Museum Wales number some 180,000 lots from many different collections which have been amalgamated into one systematic sequence.

The most historically important part of the collections is the Melvill-Tomlin collection which came to us in 1955 and contains over 1,000,000 specimens!

Want to find out more? Why not follow us on Twitter @CardiffCurator or @NatHistConserve or follow the hashtag #MolluscMonday to find out about this fascinating group of animals. Lots of people have been joining in so why not join in the fun!

Look out for some of our favourite hashtags, for ex. #MolluscMonday, #BotanicMonday, #WormWedneday and #FossilFriday.

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!         

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.
