Compiled by Lily Nadine Wilkes. NatSCA Volunteer.

Welcome to the January edition of NatSCA Digital Digest.

A monthly blog series featuring the latest on where to go, what to see and do in the natural history sector including jobs, exhibitions, conferences and training opportunities. We are really keen to hear more about museum re-openings, exhibition launches, virtual conferences and webinars, and new and interesting online content. If you have any top tips and recommendations for our next Digest please drop an email to blog@natsca.org.

News from the Sector 

Decolonising Natural Science Collections

Our blog has some fascinating videos from the Decolonising Natural Collections online conference. Each post includes a recording of the talk alongside the abstract and information about the author(s). Learn about how a taxidermied gorilla can tell us so much more in this presentation by Rebecca Machin. What words we use to represent Australian animals are challenged in this presentation by Jack Ashby. Decolonising the Powell-Cotton Museum is the topic of this presentation by Rachel Jennings.

All of the conference talks will eventually be published by the end of this week, so do keep an eye on our blog page for each of these posts: https://natsca.blog, and remember, you can also access all the talks directly by going to our

#NatSCAConservation Twitter Conference

Written by Lucie Mascord, NatSCA committee conservation representative.

During the week of the 18th January 2021 NatSCA will be hosting their first ever Twitter conference all on the subject of conservation.

Following on from the success of our inaugural conservation conference “Caring for Natural Science Collections” held at Oxford University Museum of Natural History back in October 2018, the NatSCA conservation working group had hopes of another conference this year. However, it was not to be, so we are changing the format and coming to you in 2021!

Given how strange this year has been we are keeping it simple. Just follow us on the week of 18th January (programme with exact dates and times to follow) on the hashtag #NatSCAConservation and we will bring the unique world of natural science conservation to you for free! Join us for this great opportunity to explore conservation work relating to the range of natural materials including bone, taxidermy, fluid preserved collections, geology, botany and entomology.

Trials From The Riverbank: Conserving a Taxidermy Otter

Written by Jen Gossman, MSc first year Conservation Practice student at Cardiff University.

I received a mounted taxidermy otter in still life pose without a base from the Tenby museum, Wales where it had been in long term storage wrapped in Tyvek. On initial examination it showed some skin shrinkage and was covered in a thick layer of dirt, grease and dust.

‘Tahemaa Transformed’ The Conservation of the Mummy Coffin at The Bournemouth Natural Science Society.

Written by Bethany Palumbo, ACR, Founder and Owner of Palumbo Conservation Services on behalf of the Bournemouth Natural Science Society.

Tahemaa has been a resident of the Bournemouth Natural Science Society since 1922, when she was donated from the Salisbury museum (fig. 1). New research indicates that she arrived in the UK in 1823 from the ancient city of Thebes, now known as Luxor, on the river Nile. Her coffin is dated from 700 BC making her approximately 2700 years old. We know from the hieroglyphics on the side of her coffin that she was the daughter of a Hor a high priest of Montu, the Flacon-God of War. Other than this we know very little about her and her life in Egypt.

Tahemaa has been at the Society for nearly 100 years but she has spent most of this time locked away from public view. In 1993, the Society decided to put her on permanent display in the Egyptology exhibition. Since then she has been seen by thousands of admirers, however due to her age and fragile condition, she is in need of urgent conservation treatment. Hundreds of years in an unstable environment have caused significant damage to the coffin. The fluctuations have caused the wood, plaster layers and paint to crack and flake. The layers of the coffin have even separated in some areas, lifting away from the wooden frame (fig 2). Many years without a display case has also resulted in a thick layer of dark, engrained dirt concealing the original colours of her decorative paintwork (fig 3).

Playing with Wire: The Conservation of a Wallaby Skeleton

Written by Caitlin Jenkins, MSc Conservation Practice student, Cardiff University and volunteer at National Museum Cardiff.

While volunteering with natural history conservator Julian Carter at National Museum Cardiff, I was given the opportunity to work on a wallaby skeleton. This was the first skeleton of any kind I had conserved. Although it initially appeared to be in relatively good condition, there were lots of small areas needing attention that made it a surprisingly complicated job.

A bony jigsaw…

The first step was to remove dirt that had built up on the bones over the years. This was cleaned away using cotton swabs and small interdental brushes dipped in a sodium bicarbonate solution; care was taken to not over-wet the bones as this can damage them.

One of the main conservation tasks was to re-wire a portion of ribcage that was hanging loose and distorting the alignment of the left side. In keeping with the pre-existing work, this required me to stabilise the free end of each rib using a single piece of wire twisted at intervals. This provided support and appropriate spacing of the bones. I had previously made jewellery using a similar technique, so my experience came in handy during the fiddliest parts!
