Ostracod Odessey – Broadcasting the Brady Collection

Written by Dan Gordon, Keeper of Biology, The Great North Museum: Hancock.

The Great North Museum : Hancock is home to many remarkable collections, but one of the most important is perhaps one of the most unfamiliar to our visitors. The Brady collection of Ostracods.

Ostracods, sometimes called Seed Shrimp, are distinctive Class of crustaceans. A shell of two intricately textured valves almost entirely envelopes their shrimp-like bodies, with just a small opening for a cluster of rapidly moving legs to poke out. As their common name suggests, most species are very small, mostly invisible to human eye, but they’re ubiquitous, busily going about their lives wherever there is permanent or temporary water, from the poles to the tropics. Some swarm the world’s oceans in vast planktonic shoals, while others live in the still, dark pools of caves, in garden ponds or even puddles.

They’re poorly known outside of academic communities, which is a real shame, because despite being fascinating creatures in their own right, they have important roles in many aquatic ecosystems, and significantly, they’re commonly encountered in the fossil record, which means that they are particularly important indicator fossils. In addition, the chemical make-up of their distinctive shells tells us about ocean acidity and temperature, which can tell us about ocean warming and climate change.

The collection was the work of George Stewardson Brady, a local man, born in Gateshead in 1832, and one of the people who pioneered the study of these animals at a time when they were relatively poorly understood.  Housed in a row of cabinets, the Brady collection is made up of nearly 3000 microscope slides with up to 100 Ostracods on each. These specimens were collected all over the world, many of them by well-known expeditions such as the HMS Challenger expeditions in the 1870s. It contains many Types, and provides a valuable resource for the study of these animals today.

Exploring Materials in Natural History Dioramas

Written by Claire Dean, Curatorial Assistant at Tullie House Museum and Art Gallery, Carlisle, and MA Preventive Conservation student at Northumbria University.

In many old dioramas, material mysteries abound. As a Curatorial Assistant at Tullie House, I’ve encountered a tree trunk made from a Robinson’s fruit juice box, a fake roof that contained fibrous signs of asbestos, and a hodgepodge of unidentifiable paints and old plastics. The museum’s new-in-post Biodiversity Curator discovered pests thriving amongst the real vegetation and a 30-year-old slice of bread in a garden scene.

Dioramas aim to create the illusion of real habitats for their taxidermy inhabitants, and they use a huge range of materials to do so. After decades of neglect and destruction there is now wider recognition that habitat dioramas can instil a sense of wonder in visitors that no amount of digital wizardry can replace. Through my dissertation research for an MA in Preventive Conservation at Northumbria University, I wanted to find out more about what materials have been used in dioramas over time, how these might impact the preservation of specimens, and what we can do to better protect the dioramas that remain. I put a call out to ask, ‘What’s in your dioramas?’ through an online survey and received 30 responses from people with experience in a range of different sized institutions and private practice.

Museo Giovanni Capellini – Wunderkammer or Modern Museum?

Written by Michela Contessi, Conservator, Museum University Network, Collezione di Geologia “Museo Giovanni Capellini”, Alma Mater Studiorum – Università di Bologna.

The Geological Collection “Museo Giovanni Capellini” is part of the University Museum Network in Bologna (SMA – Sistema Museale di Ateneo). The museum is in an 18th-century building and includes a core of 16th-century geological and paleontological collections dating back to one of the oldest natural history museums in the world, created by Ulisse Aldrovandi in 1556. Most of the two million specimens now hosted in the museum though, were acquired by Professor Giovanni Capellini (1833-1922), holder of the first chair of geology established in Italy and rector of the University of Bologna. The museum holds important (both historically and scientifically) collections of rocks, fossils and documents from all around the world (Europe, Africa, North and South America), including the 1909 cast of Diplodocus carnegii, which is a popular touristic attraction in Bologna.

However, and here comes the problem…

After Capellini’s death in 1922 little was done for the museum, in the early 1960s, when the new-born Institute of Geology and Paleontology was built, the museum building was literally cut in half and the collections crowded into half the original space.

Structural issues arose due to this move, and the museum was closed to the public for almost 30 years. After a major renovation, funded for the ninth centenary anniversary of the University in 1988, the museum was given a new lighting and heating system, reopened to the public and it welcomes several thousand visitors a year since then. The building is now solid (as an old 500-year-old lady can be), but again nothing has been done since, and what looked like a good compromise in the eighties is now obsolete.

A Foot In The Door – Finding Collections Work As A Trailing Spouse In A Foreign Country

Written by Caroline Grounds, Freelance Zoological Collections Assistant, Musée national d’histoire naturelle, Luxembourg.

I arrived in Luxembourg 8 years ago when my husband accepted a job offer here, not knowing much about the tiny country (“where exactly is Luxembourg?”), and with a new baby in tow.

I had become accustomed to the trailing expat spouse role, so I was happy for a new adventure, though the hardest part about moving, especially to a country where you don’t speak the language, is finding your niche in which you can carve out something of your own.

As a former Biology teacher, most of my previous museum experience was in science education, as a volunteer at the NHM in London, and the George C. Page museum (La Brea Tar Pits) in Los Angeles, and I was keen to get involved in the Luxembourg Natural History Museum in any way, shape or form. Something about being around the wonders of nature, whether outside or housed in a building, is inspiring to me and, surrounded by like-minded people, where I truly feel like I’m supposed to be.

Not speaking any of the official local languages however (Luxembourgish, German and French), I quickly found that it would be difficult to find work, even on a voluntary basis as I had before. I submitted my CV to the museum anyway, and endured a rather painful phone call in very bad schoolgirl French (mine, not theirs!), which, much to my amazement, led to one of the researchers contacting me for help proofreading his research papers, which were being published in English. That schoolgirl French came in useful after all!

A Remarkable Collection Of Fossil Birds From The Eocene

Written by Andrew Kitchener, Principal Curator of Vertebrates, National Museums Scotland.

In November 2021 National Museums Scotland acquired a remarkable collection of fossil bird skeletons dating from the Eocene, approximately 54.6-55 million years ago. The story of how this collection ended up in Edinburgh is a very long one and began more than 25 years ago. 

“Please can you show me your collection of Eocene birds?” This was the question that greeted me when I first met a Mr Michael Daniels more than 25 years ago. Visiting the museum with his wife Pam and his daughter Caroline, who lived in Edinburgh, this meeting would be the beginning of a long friendship and long-term correspondence, which ended sadly in 2021. My answer was “Well I would love to show you our collection of Eocene birds, but we don’t have any.” Michael proceeded to tell me about his remarkable collection of several hundred skeletons and part skeletons that he had discovered in nodules of the London Clay, which had eroded out of the cliffs at Walton-on-the-Naze in Essex. In later years I visited Michael and Pam at their home and got to see the collection in its countless drawers and boxes in his study. I was astonished at the amazing variety of specimens of all shapes and sizes.  Many of the bones were minuscule, requiring great patience and skill to extract from the substrate.

Michael Daniels was a passionate self-taught palaeontologist, who visited various fossil sites outside London and further afield in southern England from his home at Loughton near Epping Forest. He developed a more specialised interest in the Tertiary Eocene London Clay in the early 1970s, having been a founder member of the Tertiary Research Group in 1969. On retirement in 1985 he moved with his wife to Holland-on-Sea, so that he could pursue this interest at Walton-on-the-Naze.
