The introduction and growth of the railway network in the first half of the 19th century not only revolutionised travel and transport of goods for many, but it also had a profound effect on the science of geology. Not only did it make it easier for geologists to cover the ground quickly – but the railway cuttings for the new lines revealed rock outcrops that had never before been seen.
One of the first to take advantage of the new possibilities was John Phillips (1800–1874), the first Keeper of the Museum, and nephew of William Smith, often referred to as the Father of English Geology. Phillips was orphaned at the age of eight, along with his younger sister Anne, and their younger brother, Jenkin.
John was educated at Smith’s expense and learned about geology at his uncle’s knee. He was reunited with Anne in 1829. Neither married and they lived together until her death, with Anne serving as John’s housekeeper, moral support, confidant and geological companion. John went on to become a skilled palaeontologist, field geologist and prolific author. He also became a great train enthusiast.
On 23 July 1835, John wrote to Anne with this vivid description of his first train journey – travelling on a ‘flying steed of Iron,’ from Manchester to Liverpool on his way to Dublin.
“…My dear Annie, You must certainly come to feel the strange impression of this flying Steed of Iron. It does so hurry & flurry on, you shake & sleep & start & wonder at the gliding Houses, trees & Churches, — the trains which meet & pass you’ like the swiftest birds with a rushing sound & the Master power (Steam) & a confused picture of colours & forms not at all distinct as Men[,] Women, Carriages &c that it is all like magic & can not be understood by a mere description. Then you are dragged through a tunnel full of gas lamps, then laid hold of by ruffian porters & crammed into an Omnibus whether you will or no & whirled away the man who guides (only) knows whither. “
Phillips quickly became a convert to train travel. He was often travelling from his then base in York to earn money by giving lecture courses by subscription to members of the various newly formed Philosophical societies, so enjoyed the relative convenience and faster travel times railways offered – even though, as he wrote to Anne in March 1841, the trains were not always punctual.
“I found the Train of yesternight very good travelling till we entered on the Leeds & Manchester line at Normanton. Then began this singular amusement: to lose time so as to arrive in 4 hours from Leeds, the time really required being 2 1/2 hours. We did this odd railway feat by stopping 5 minutes each at about 10 stations & using all possible precautions not to go too fast. This is said to be on account of the recent embankments not allowing of rapid transit: but some of the trains are faster. We reached Manchester at 10:30, that is to say in 4 hours from York.”
In the second part of Railway Geology, Nina will take a look at how the expansion of the railway network spawned a new form of popular science and travel writing.
This week my colleagues and I announced the discovery of a new species of mammal from the time of dinosaurs. It is one of two rare skeletons we’re studying from the Isle of Skye in Scotland. These mouse-like animals lived in the Middle Jurassic (166 million years ago), and tell us about the evolution of mammals in the time of dinosaurs.
The two fossils belong to Borealestes serendipitous and Borealestes cuillinensis. B. serendipitous was the first Jurassic mammal ever found in Scotland, known originally from pieces of fossil jaw found on Skye in 1971. In our new paper, we describe the skull of a partial skeleton of this species, found in 1972 by the original discoverer of the site, Dr Michael Waldman and his colleague Prof Robert Savage. But this exceptional fossil lay unstudied for over 40 years. Only now is it giving up its secrets thanks to powerful synchrotron X-ray scans, which reveal the anatomy in incredible detail.
The other fossil skeleton was found in 2018 by my colleague Prof Richard Butler. After taking it back to the lab and CT-scanning it, we realised it was a new species. We named it Borealestes cuillinensis in honour of the Cuillin mountain range on Skye (Gaelic: An Cuiltheann), a stunningly jagged set of peaks that overlooks where the discovery was made.
Most ancient mammals are only known from a few teeth and jaws, so these skeletons are exceptionally rare. They are currently the most complete Jurassic mammals described from the UK.
The Middle Jurassic is an important time in animal evolution, because it marks an increase in the diversity of lots of different groups. Just afterwards, in the Late Jurassic, there are many new species of mammals, amphibians, small reptiles and dinosaurs, which flourish into the Cretaceous period. All of this diversity began in the Middle Jurassic, but fossils from that time are rare, making it difficult to unpick the causes of these changes. This means that any material from that time period is extremely important to our understanding of the course of evolution, and the drivers of animal diversity.
Our team have been carrying out fieldwork and research on Skye for the last decade. It includes researchers from National Museums Scotland and the universities of Oxford and Birmingham. We are working on many more exciting fossils from the island, so keep an eye out for the next discovery!

Cemeteries not only provide a peaceful place to commemorate the dead, and observe and enjoy nature; they are also wonderful repositories for the study of local history and art. But that’s not all. Cemeteries also offer an easy introduction to science that anyone can enjoy.
A visit to a cemetery presents a wonderful way to learn about geology and the other sciences, such as chemistry, physics and engineering, that underpin it. For geologists – whether amateur, student or professional – almost any urban cemetery provides a valuable opportunity to carry out scientific fieldwork at leisure, right on the doorstep, and at no cost.
Geology on show
Because gravestones are made from a wide variety of rock types formed in a range of geological settings, cemeteries can be geological treasure-troves. Many headstones are made of polished stone, so reveal details – such as minerals and crystal features – that are not easy to see elsewhere. Some demonstrate the textures and mineral composition of igneous rocks – rocks formed when molten magma cooled and solidified. Others are happy hunting grounds for lovers of fossils. Some gravestones reveal sedimentary structures that show how the rock was originally deposited. Others provide clues to earth movements and environments that occurred hundreds of millions of years ago.
For those interested in engineering, examination of gravestones can also provide useful information about topics ranging from weathering of stone to atmospheric chemistry, effects of pollution, stability and settling in soils and land drainage.
Cemeteries in Oxford include ancient churchyards, such as St Andrews Headington, as well as Victorian cemeteries like Holywell (pictured top) and St Sepulchres, and more modern burial grounds, such as Headington Municipal cemetery. Together they exhibit the main features and stone types that can be seen in cemeteries all around Britain.
In the short video below, filmed in the churchyard of St Mary and John in Oxford’s Cowley Road, Philip Powell and I introduce the basics and show you how to get started in exploring these geological gems. If you want to learn more, visit www.gravestonegeology.uk. But be warned – gravestone geology can be addictive. Once you’ve got your eye in, you’ll never look at cemeteries in the same way again!
Elsa Panciroli recently joined the Museum research team as an Early Career Leverhulme Research Fellow. Elsa is a Scottish palaeontologist, whose studies focus on the early evolutionary origins of mammals, working extensively on fossils from the Isle of Skye. Here she tells us how her work will combine studies of mammal evolution with stunning new fossil finds from Scotland.
We are mammals. This means we share a common ancestor with creatures as different as hippos, opossums and platypuses. All of us are united in one taxonomic group by a suite of characteristics in our bodies, but principally, that we feed our young on milk. Every mammal from a baboon to a blue whale produces milk for their offspring, and this makes us unique among animals alive on Earth today.
But not all mammals bring their young up in the same way; raising a kitten is nothing like raising a kangaroo or a platypus. Kittens are born stumbling around with their eyes closed, while platypus babies are laid in eggs – yes eggs – and when they hatch they look like little scampi. Both are underdeveloped at birth or hatching, but that’s nothing compared to kangaroos. They leave the womb only millimetres in length, and wriggle their way like living jellybeans toward a teat in the marsupial pouch, where they latch on. Only after two months of milk-drinking are they able to hop for themselves and leave the pouch.
The different ways that mammals are born and grow is a huge area of scientific research. But there are still some major questions to answer about the evolution of these growth patterns. When did the ancestors of mammals stop laying eggs? Were they born defenceless, or able to fend for themselves? How quickly did they grow up and how long did they live?
Over the next three years at the Museum, I’ll be looking for evidence in the fossil record to help us try and answer some of these questions. I’ll study living mammals to understand how they are born and grow, combining this information with data from some of the amazing fossils being found on the Isle of Skye. With collaborators in South Africa I’ll try and work out how the ancestors of mammals developed, and what this means for the bigger picture of the origin of mammals as a group.
Alongside my main research I hope to share lots of stories about our fossil past through the museum’s fantastic public engagement programme. I’m also very active on social media, and I write about science for online and in print publications. So if you see me on your next visit to the building, or find me online, feel free to ask about my research! I look forward to seeing you, and sharing more about the elusive and exciting origins of mammals – and ourselves.
Worms, fish and … Greenland? Hugely different topics which all have one thing in common – the Museum’s First Animals exhibition online lecture series. Running every other Wednesday from May until September 2020, this series provided a fantastic insight into a wide range of topics about how the first animals lived, died, and are studied. And illustrator Rachel Simpson tells us how she drew her way through them all…
I came across this lecture series just before the first talk and I knew I had to sign up. Drawing along to lectures is a hobby I seem to have developed in the past few months as we went into lockdown and didn’t have much to do. It’s the perfect combination for me – an opportunity to listen to interesting topics and brush up on my live drawing skills at the same time. There’s no pause button, there’s no asking the webinar speaker to just go back a few slides and hold on a minute whilst I draw; it’s fast paced, it’s inspiring and it’s a great way to just create art.
I’ve done some illustration work with the Museum before so I knew that it was going to be fun. In 2018, I worked with Dr Jack Matthews illustrating Ediacaran Fossils as part of a collaborative university project between the University of Plymouth and the Museum. I was also lucky enough to be able to go to Newfoundland and see some of the fossils myself, again with Jack. This was such an incredible opportunity and opened up a whole new world of science/art collaborative work which I didn’t know about before.
The First Animals series kicked off with Jack’s talk titled Don’t walk on the rocks! – an interesting insight into how protective “Barma Booties” (some rather funky socks worn to protect fossil sites such as Mistaken Point, Newfoundland) might actually be damaging to the fossils they’re meant to be protecting. Having been to Mistaken Point myself and worn these socks, it was interesting to hear about their possible impact and to learn about the experiments conducted to prove this fact.
Of course, at the same time as Jack was talking, I was scribbling away in my sketchbook trying to form some sort of visual response to the talk. At the end of the hour I’d managed a portrait of Jack and a family of Barma-Booted tourists trampling on the fossil site. It was a start. The beginning of my lecture drawings and a point at which I can retrospectively say started a new hobby.
Over the following weeks we heard about worms from Dr Luke Parry; 3D reconstruction from Dr Imran Rahman; The Chronicles of Charnia by Dr Frankie Dunn; and the first animal skeletons from Dr Duncan Murdock. Luckily for me, all the speakers kindly included photos and descriptions of the topics they were discussing which meant that I was never short of visual inspiration for my drawings. After all, it’s hard to try and draw an annelid worm if you’ve never seen one before.
I love to look at the fossils being discussed and then try to draw a little character or creature inspired by them. They’re not scientifically accurate, nor are they always anatomically correct, but they have character and begin to bring to life the essence of something that’s been dead for many millennia. The fossils are obviously stone-coloured so I take as many liberties as possible when it comes to colour. I like to make them as vibrant and colourful as I can, so although they probably didn’t look like that, that’s how I like to think they looked.

Charnias galore! They come in all different shapes and sizes.

Within my wider practice I like to use stamps as the basis of my illustrations. These however, are time consuming to make and therefore not very suitable for when I’m drawing along to lectures. As a result I’ve found myself using brush pens and pencils to make my lecture illustrations. If you’re interested in art, or thinking about getting into art, brush pens will be your best purchase. They create a wonderful quality of line and are quick and easy to use. Whereas a ballpoint pen will give you one line of a certain weight and thickness, brush pens are versatile and depending on the pressure applied, the line quality will change.
For the first few lectures I only used brush pens, but later on I decided to use coloured pencils as well, to add depth to the drawings. As I got more used to drawing in lectures I found that I was making more illustrations per talk. Early on, I managed to finish maybe a double page in my sketchbook but towards the end of the series I was filling four double pages! It’s amazing what a little bit of practice can do.
As the weeks went by the talks continued and we heard about the evolutionary origin of animals from Museum director Professor Paul Smith; an introduction to taphonomy, the study of fossilisation, by Professor Sarah Gabbott; and how the first animals moved by Professor Shuhai Xiao.
During this time I became a lot more confident drawing the specimens; looking back I can see that this was the period in which my work developed the most. My drawings began to have more character and life. The landscape drawings were slowly becoming more realistic and detailed. This was great news for me as this whole endeavour began as a way to practice my drawing skills in a timed environment.
Paul Smith’s lecture has to be my favourite of them all. He gave a wonderful talk all about the Evolutionary Origin of Animals and talked us through his fieldwork expedition to Greenland. How I would have loved to have been on that trip!

One of my favourite drawing from the lecture series! Drawn with Tombow brush pens and Polychromo pencils.
It was during Paul’s talk that I made one of my favourite drawings from the series – the plane –and coincidentally it was also at this point that I bought myself some new polychromo pencils. I started using these pencils in my illustrations on top of the Tombow brush pens. The pencils added a softer layer on top of the solid base colour from the brush pens and meant that I could add more details, shading and most importantly, the characterful eyes I love to add to my drawings.
Fish and animal studies from Professor Sarah Gabbott’s introduction to taphonomy, the study of the processes of fossilisation.
Imagine being the owner of this house and being told there were found fossils on your roof! Drawing from Professor Shuhai Xiao’s talk.
Buoyed by this development in my drawings, and some lovely responses to my work on Instagram and Twitter, I raced through the next few weeks of talks and made twelve pages of drawings over the next four talks. Professor Derek Briggs told us all about extraordinary soft-bodied fossils; Professor Gabriela Mángano told us about the trace fossil record; and Professor Rachel Wood gave us her thoughts about what triggered the Cambrian Explosion.

Another of my favourite drawings from the series was from Derek Briggs talk about extraordinary soft-bodied fossils. Here, I made a small series of drawings based on some of the animals mentioned in the talk and as soon as I’d finished drawing them I wished that they were real and that I could pop them in a fish tank and keep them as pets. These drawings got the best response on social media too and it’s wonderful now to look back and compare these drawings to the work I was creating at the beginning of the series.
The First Animals series may be over but keep your Wednesday evenings free because there are more talks to come! The next series, “Visions of Nature”, starts on 8 October so make sure you join us then! A huge thank you to all the speakers, to Jack for hosting and to the Museum for running the events.
Earwigs are fascinating creatures. Belonging to the order Dermaptera, these insects can be easily recognised by their rear pincers, which are used for hunting, defence, or mating. But perhaps the most striking feature of earwigs is usually hidden – most can fly with wings that are folded to become 15 times smaller than their original surface area, and tucked away under small leathery forewings.
With protected wings and fully mobile abdomens, these insects can wriggle into the soil and other narrow spaces while maintaining the ability to fly. This is a combination very few insects achieve.
I have been working on research led by Dr Kazuya Saito from Kyushu University in Japan, which presents a geometrical method to design earwig wing-inspired fans. These fans could be used in many practical applications, from daily use articles such as fans or umbrellas, to mechanical engineering or aerospace structures such as drone wings, antennae reflectors or energy-absorbing panels!
Dr Saito came to Oxford last year for a six-month research stay at Prof Zhong You’s lab, in the Department of Engineering Science at the University of Oxford. He introduced me to biomimetics, an ever-growing field aiming to replicate nature for a wide range of applications.
Biological structures have been optimised by the pressures of natural selection over tens of millions of years, so there is much to learn from them. Dr Saito had previously worked on the wing folding of beetles, but now he wanted to tackle the insect group that folds its wings most compactly – the earwigs.
He was developing a design method and an associated software to re-create and customise the wing folding of the earwig hind wing, in order to use it in highly compact structures which can be efficiently transported and deployed. Earwigs were required!
Here at the Museum we provided access to our insect collections, including earwig specimens from different species having their hind wings pinned unfolded. These were useful to inform the geometrical method that Saito had been devising.
Dr Saito was also interested in learning about the evolution of earwigs and finding out when in deep time their characteristic crease pattern established. Some fossils of Jurassic earwigs show hints of possessing the same wing structure and folding pattern of their relatives today.
However, distant earwig relatives that lived about 280 million years ago during the Permian, the protelytropterans, possessed a different – yet related – wing shape and folding pattern. That provided the chance to test the potential and reliability of Saito’s geometrical method, as all earwigs have very similar wings due to their specialised function.
The geometrical method turned out to be successful at reconstructing the wing folding pattern of protelytropterans as well, revealing that both this extinct group and today’s earwigs have been constrained during evolution by the same geometrical rules that underpin the new geometrical design method devised by Dr Saito. In other words, the fossils were able to inform state-of-the-art applications: palaeontology is not only the science of the past, but can also be a science of the future!
We were also able to hypothesise intermediate extinct forms – somewhere between protelytropterans and living earwigs – assuming that earwigs evolved from a form closely resembling the protelytropterans.
As a collaboration between engineers and palaeobiologists, this research is a great example of the benefits of a multidisciplinary approach in science and technology. It also demonstrates how even a minute portion of the wealth of data held in natural history collections can be used for cutting-edge research, and why it is so important to keep preserving it for future generations.
Soon these earwig-inspired deployable structures might be inside your backpacks or used in satellites orbiting around the Earth. Nature continues to be our greatest source of inspiration.
