A rare and special rock, a piece of the upper mantle was donated to the NHM by researchers of Macquarie University, Sydney, Australia. This specimen is one piece of a large collection of mantle xenoliths that is being donated to the NHM.
Deadly predators. Venomous machines. Stealth assassins. Yes, it’s the robber flies, or assassin flies if you’re from across the pond. These beautiful, lethal creatures are, to my mind, some of the most amazing species on the planet, with not only some amazing adaptations to their predatory lifestyle but also exhibiting a great morphological variety – including some of the most hirsute insects on the planet.
On 13 July 2017 the Museum unveiled Hope the blue whale, a spectacular 25-metre-long specimen suspended from the ceiling of the Museum’s central space, Hintze Hall.
Just after the BBC broadcast their Horizon documentary about the new installation, Dippy and the Whale, Richard Sabin, Principal Curator of Mammals, and Lorraine Cornish, Head of Conservation, joined host David Urry for a special #NHM_Live talking about the history, conservation and story behind Hope, direct from our new Whales: Beneath the surface exhibition.

The Museum’s conservators were the stars of our second broadcast in the first #NHM_Live series, where we took a look at how they repair and maintain the millions of specimens in the collections.
Camilla Tham and Alison Shean were joined by conservators Arianna Bernucci and Cheryl Lynn to talk about mummified cats, Archaeopteryx, 1.3 kg of dust from a single specimen and some of the major specimens that will feature in the upcoming #Whales: Beneath the Surface exhibition.
It has been several months since my last post looking at blue whale on the move but finally the long process of cleaning and conserving each individual bone has been successfully completed and the conservators are now just embarking on surface scanning the bones in high definition. Conservation can be an extremely slow process but it is worth the time and effort. During the past 9 months the team have cleaned and conserved over 220 individual bones. This equates to over 110m2 of whale bone surface area.
During this time we also planned the final position and articulation of the whale for its suspension in Hintze Hall so the armature design could commence. This post outlines the conservation treatment and articulation planning phase of this project.
Although it’s only been a few weeks since I looked at ‘what lies beneath,’ it feels like a lifetime as so much has happened to our blue whale skeleton in a relatively short space of time. The biggest challenge of de-installing the skeleton from the Mammals Hall has been completed with resounding success and the Conservators are now busy with the next phase of cleaning and conserving each individual bone.
We all knew that safely removing the bones from the 81 year old armature was not going to be easy. Add in the fact that it was suspended over a large model of a blue whale and several other specimens with very little room for manoeuvre and you start to appreciate the whale-sized nature of the project. This post outlines what happened during the de-install.
The team have been busy in the 3 weeks since my last post, studying the blue whale skeleton and documenting its condition. The first stage was to record the initial condition of the skeleton, including the coating of dust that has accumulated over time, and to start to identify areas which would require attention prior to dismantling.
Dust particles that are deposited on museum objects will typically consist of fibrous material (aka “fluff”) and non-fibrous particulates. Dust is hygroscopic and can accelerate biological, chemical and physical deterioration of specimens and even though it is over 6 metres above the ground, the whale skeleton is a dust attractor so a regular cleaning schedule is important where practicable. On this occasion, over 1.3 kilos of dust was removed from the blue whale skeleton during this initial clean.
The stunning 25 metre long skeleton of a blue whale (Balaenoptera musculus) currently suspended in the Museum’s Mammals and blue whale gallery since 1934 is to be taken down in January 2016. After an extensive period of cleaning and conservation it will then be re-suspended from the ceiling of the Hintze Hall in the summer of 2017.
Following months of careful consideration the blue whale skeleton has been chosen to take centre stage at the Museum, to give an immediate introduction that illustrates our research into the rich biodiversity of life on Earth and a sustainable future, as well as the origins and evolution of that life.
Moving a blue whale around is quite literally an enormous project which involves many specialists including curators, project managers, scaffolders, structural engineers, specimen handlers, and mount makers, to name but a few. Central to this project are the conservators who will be ensuring the skeleton is given the due care and attention it needs.
So exactly how do you work on a large specimen suspended over 6 metres above the ground with many other specimens and models surrounding it? That’s the story we aim to tell in our upcoming posts in our new Conservators blog.
