I am a palaeontologist based at the University of Manchester. Much of my work employs X-ray techniques to better understand early terrestrial animals and ecosystems. I currently hold an 1851 Research Fellowship investigating the origin and early evolution of insects. The links above will take you to further details about me, my research, journalism and photography, and my contact details. News can be found below.
I'm pleased to be able to link to another new paper, this one with colleagues from the Universities of Oxford and Bristol, and the Natural History Museum, London, amongst others. It's something a bit new for me - in it we use a range of techniques to describe structures possibly associated with life in one of the oldest known sedimentary rocks: the 3.46-billion-year-old Apex Chert, Austrlia. More information below:

If you'd like some more info, you can read about the discovery here. That's it for now, but more coming soon!
It's been a long time since my last update - not because things haven't been happening, but because I've been a little too absorbed in them to remember to post them here! In fact, several things have happaned in that time. A new paper has appeared, playing with fossils a little older than I am used to - and describing some of the first biomineralising animals:
Streng, M., Butler, A. D., Peel, J. S., Garwood, R.J., & Caron, J-B. 2016. A new family of Cambrian rhynchonelliformean brachiopods (Order Naukatida) with an aberrant coral-like morphology. Palaeontology 59(2): 269-293. doi: 10.1111/pala.12226 [View]
The following finalised papers have also appeared in their respective journals since the last update:
We've also had monthly updates to Palaeontology [online] - click on the image below to visit the site:
Three more papers have recently been accepted: as soon as those appear I shall post links. I've also given lots of talks, all of which you can find on an updated publications page.
A couple more contributions have appeared. First is a paper with colleagues from Manchester, using micro-CT to better understand pathologies in the bones of birds and dinosaurs:
I also recently wrote an article introducing the basics of using compational techniques to understand fossils for McGrawHill:
Garwood, R.J. 2015. Analysis of fossil organisms using computer techniques. AccessScience. McGraw-Hill Education. doi:10.1036/1097-8542.YB150677
That's it for now, but more on the way!
Another paper to which I have been fortunate enough to contribute was published today, this time led by colleagues at Harvard and the University of New England. The paper documents twenty Anolis lizards in amber with the aid of micro CT. Details below:
Sherratt, E., Castañeda, M., Garwood, R.J., Mahler, L.D., Sangere, T.J., Herrel, A., de Queiroz, K. & Losos, J.B. . In press. Amber fossils demonstrate deep-time stability of Caribbean lizard communities. PNAS doi: 10.1073/pnas.1506516112 [View]
Several new Palaeontology [online] articles have also appeared in the last few months. Click on the image below to visit the site:
One of the papers I mentioned below has just appeared in press - led by colleagues from Oxford, this reports the CT-based reconstruction of an early ray-finned fish called Cheirolepis. You can check it out here:
Giles, S., Coates, M.I., Garwood, R.J, Brazeau, M.D., Atwood, R., Johanson, Z. & Friedman, M.. In press. Endoskeletal structure in Cheirolepis (Osteichthyes, Actinopterygii), an early ray-finned fish. Palaeontology doi: 10.1111/pala.12182 [View]
It's been a busy few months (including a relocation!), with a number of papers coming out soon to show for it. The first of these is a new effort which recently appeared reassesses a number of fossils which were originally identified as spiders. With the aid of micro-CT, my coauthors, and I suggest that these in fact represent unusual Harvestmen. More details available at the link below:

Happy new year. I am very pleased to say that on the first of January, I joined the School of Earth, Atmospheric and Environmental Sciences at the University of Manchester as a lecturer in Earth Sciences. Here is the official announcement.
There's also a new Palaeontology [online] article - Dinosaurs down under - available, by Stephen Poropat. To read, click below:
I'm pleased to report that I have been selected as one of the SSI's Fellows for 2015, to provide training in open source packages for tomographic reconstruction. You can find more details here.
Last week saw the appearance of a new paper that I've been working on with Joachim and Carolin Haug from LMU Munich, looking at the fossil record of insect development. In it, we provide an overview of the work on fossil insect nymphs to date, and the impact this work has on theories surrounding wings origins and development of complete metamorphosis in the insects. We also report novel descriptions of a number of fossil nymphs. More details at the link below:
Palaeontology [online] also has a new article - this one by Dave Hone, on Tyrannosaurs. Do check it out:
Another new paper has appeared in which my colleague Jason Dunlop and use high resolution CT to describe species from two extinct arachnid groups, based on fossils from the Carboniferous housed in the NHM, London (~315 million years old). The paper, also in PeerJ, also places most of the fossils we have reconstructed to date, and other very well-preserved fossils - into an analysis of the evolutionary relationships of the arachnids. You can access the paper by clicking on the image or citation below:
This is a featured article, and associated with this you can read an interview with me here on the journal blog. We also have a new Palaeontology [online] article on annelid worms by my friend a colleague Luke Parry. Please click on the logo below to check it out:
A new paper with colleagues from the Natural History Museum, and Imperial College, London, has appeared in the open access journal PeerJ. The publication reports a fossil cone revealed through CT scanning in a synchrotron. You can find more information by clicking on the link or image - which shows a CT slice through the cone - below:

An article providing an overview of what a bunch of us have been playing with for the last few years has appeared in the latest issue of Science News. This featuring the work of my colleagues Imran Rahman and John Cunningham, and myself, amongst others. It also made the cover of the magazine - click for more information:
The article is paywalled, but please do email me if you would like a copy. There's also been a new Palaeontology [online] article since last time. This one is on Palaeoart, courtesy of Mark P. Witton:
Four papers to which Ihave contributed are now waiting to appear in press, so more soon.
A new paper has just appeared in press at the Zoological Journal of the Linnean Society. This paper - with colleagues from the University of Oxford and Museum für Naturkunde, Berlin - features a reconstruction of the trigontoarbid arachnid Trigonotarbus johnsoni, and the first cladistic analysis of the extinct trigonotarbid arachnids - part of an effort of mine in the last year or two to learn cladistics (more from this coming soon!). The paper can be accessed by clicking the journal name below, and I've included a neat reconstruction of a range of trigonotarbids to scale by my very-talented coauthor Jason Dunlop (scale bar 10mm).
Jones, F.*, Dunlop, J.A., Friedman, M., & Garwood, R.J*. In press. Trigonotarbus johnsoni Pocock, 1911, revealed by X-ray computed tomography, with a cladistic analysis of the extinct trigonotarbid arachnids. Zoological Journal of the Linnean Society (* = corresponding author)
Another two papers have just been accepted, and one more submitted since my last update - more details as these appear. In the meantime, do check out our latest Palaeontoloy [online] article on dinosaur palaeopathology by my very talented colleague at Manchester, Jennifer Anné (otherwise known as Indy). Click on the diseased dinosaur bone below for more info.
A new paper has just appeared, in which I - with my colleague Jason Dunlop from the Museum für Naturkunde, Berlin - use fossils from the Devonian Rhynie Chert to work out the range of motion in an extinct arahcnid's limbs. We then use the open source software Blender to create a reconstruction of the animal's gait using its centre of mass and limb articulations. The supplementary information includes an introductory guide on how to use the software. This by no means comprehensive, and indeed, the study doesn't make use of all Blender's impressive capabilities, but hopefully it will lessen the application's learning curve. Details of the paper are below:
The paper has picked up some interesting press coverage, including: the BBC news website, New Scientist, io9, Motherboard, IFLScience, Discovery News, The Daily Mail, The Telegraph, and Entomology Today. I've embedded the video from the paper below, please do check it out!
Televised coverage includes ITN, and I did a live interview for BBC World News at their London Studio. In other news, Palaeontology [online] has just turned three, and we celebrate with a new article looking back over the previous three years. Link below:
That's it for now, but more soon.
There's been a slight break since my last update thanks to synchrotron beamtime and trips to Sardinia then the Faroes. In that time, a new paper has appeared from my colleague Jason Dunlop and myself, in which we use microtomography to highlight the palaeobiology of a Carboniferous arachnid Eophrynus prestvicii, and sort out the systematics of the group to which it belongs. Click on the image below to check out a copy - it's open access:
Dunlop, J.A. & Garwood, R.J. 2014. Tomographic reconstruction and palaeobiology of the trigonotarbid arachnid Eophrynus prestvicii (Buckland, 1837). Acta Palaeontologica Polonica 59(2): 443–454. doi:10.4202/app.2012.0032 [View]
The following opinion piece also appeared in Nature today, outlining the two body problem, as it applies to academics, its origins and consequences, and what universities can do to mitigate its effects:
Any feedback or discussion on either of these publications is, naturally, very welcome. There have also been two new Palaeontology [online] articles since I last updated, on arthropod-plant interactions, and a group called the placodonts. Please do check them out:
Two more papers should appear in the next couple of months, so I'll update the website when those appear. In the meantime, in early July I'll be helping out with Manchester's stand at the Royal Society Summer of Science exhibiton. More details of the stand below. Please do come and say hello if you're attending.
A new paper has just appeared, in which my coauthors and I: describe a new harvestman species and suborder; conduct some molecular dating; and identify a vestigial signal in the embryological gene expression of an extant species for structures visible in the fossil. It seems to have sparked an interest, and press coverage so far includes Wired, National Geographic, Discovery, and Huffington Post. A clearer picture of the impact through the article's entry on altmetric. The paper is open access, and available at the following location:
Garwood, R.J.*, Sharma, P.*, Dunlop, J.A. & Giribet, G. In press. A Paleozoic Stem Group to Mite Harvestmen Revealed through Integration of Phylogenetics and Development. Current Biology (* = equal contributors).
Here is a closeup of the fossil itself:
The following paper has also just been accepted:
Jones, F.*, Dunlop, J.A., Friedman, M., & Garwood, R.J*. Accepted. A cladistic analysis of the trigonotarbid arachnids. Zoological Journal of the Linnean Society (* = corresponding author)
Since my last post there have been two new Palaeontology [online] articles, one on things called latitudinal biodiversity gradient, and one on dinosaur reproduction. Links below:
Finally, since I've just returned from a trip to work with colleagues in Uppsala, I thought I would post an image of one of the smally shelly fossils (the hard parts of some of the earliest animals) we were working on whilst I was there:
So that's it for now - more coming soon!
Hello from Berlin. I'm currently on an EU synthesys visit to work with colleagues at the Museum Fur Naturkunde. Whilst here, the following article has appeared:
Garwood, R.J. 2014. Life as a palaeontologist: Palaeontology for dummies, Part 2. Palaeontology Online 4(2):1-10. [View]
Following on from Part One which is linked below, Palaeontology for Dummies - Part Two is a brief introduction to the history of palaeontology, and how we got to where we are now. I hope it is interesting, please do check it out. The four papers mentioned below, plus a couple more, are now complete and approaching submission: I will post updates as they appear in the near future.
Happy new year! At the beginning of December the following publication went live:
Garwood, R.J. 2013. Life as a palaeontologist: Palaeontology for dummies, Part 1. Palaeontology Online 3(12):1-11. [View]
This provides an introduction to palaeontology highlighting what it is, what it is not, and also providing an overview of the field as it currently stands. I hope it proves interesting! Keep an eye open for part two - which outlines the history of palaeontology - in the near future. The Paleonturología 12 Prize Winner's Book is now also freely available, details below. Please do check it out. Furthermore an updated ebook with glossary, and hardback version of Techniques for Virtual Palaeontology is also now available:

Finally, we have another new palaeontology online for this month - this time about body size in fossils courtesy of Mark Bell. You can check it out at the link below:
I'm currently working on a four papers for submission in the first quarter of 2014, so more news will be forthcoming!
It's been another busy three months, hence the silence. In that time our Wiley entry to the Analytical Methods in Earth and Environmental Science series has finally appeared - currently it is available as an ebook, with hardback in January 2014. It can be purchased here:
The book associated with the Paleonturología 12 mentioned below is now in production and should appear in December. I've also given several talks over the last few weeks, which can be found in the section Publications. We have also posted three Palaeontology online articles in that time - two Fossil Focus pieces, one on encephalized bipedal apes, the other on Heterostraci, and an article on ancient DNA. Links below. Other than that, we have had a very successful beamtime at I12, Diamond Light Source, and been awarded beamtime at SLS, Switzerland. Several more papers are approaching completion, so watch this space!
It's been a while since I last wrote an update, largely because I've spent the last couple of months travelling and scanning. This has included a trip to Berlin to finish a trigonotarbid phylogeny, and build a new arachnid one with a colleague. The trip was a great success, and lots else has happened since the last update. The following paper has now been accepted, and I've included a preview of the model we've created and animated for the paper below:
Garwood, R.J. & Dunlop, J.A. Accepted. The walking dead: Blender as a tool for palaeontologists. Journal of Palaeontology.
The accessible account of our 2011 paper required for the Paleonturología 12 prize is also complete, including 18 figures. It will be used to print a small book in Spanish and English introducing terrestrialisation, CT scanning, and the fossil record of the harvestmen, which should be available from December:
Garwood, R.J., Dunlop, J.A., Giribet, G. & Sutton, M.D. Accepted. Fossil harvestmen. Paleonturología 12 (Prize Winner's Book).
The following paper has been submitted since last time:
Garwood, R. J., Sharma, P., Dunlop, J. A., & Giribet, G. Submitted. Early harvestman evolution: Perspectives from gene expression data and Palaeozoic fossils.
I'm also giving two talks in the near future, the ToScA presentation mentioned below, and a talk for TEDx Albertopolis Salon in early September. More details when I have them. You can also find me at this year's Science uncovered on the last Friday of September.
Finally, there are two new Palaeontology [online] posts - one on exceptional preservation of fossils in concretions by Victoria McCoy, and one on naming fossil species by Chloe Marquart. Please do check them out!
I've just returned from two weeks of fieldwork in northern Scotland, and the chrysalis paper, mentioned below, is now available to download here. It's open access. You can find coverage of the paper at the following links: 1, 2, 3, 4, 5, 6, 7. I've also been invited to speak at the first annual Tomography for Scientific Advancement event, or ToScA, at the Natural History Museum, London, this August. More details.
I'm pleased to report that our book - Techniques for Virtual Palaeontology - is now in production, so should be out in the next few months. The chrysalis paper mentioned below has now been accepted and will appear in press next Tuesday - some images from the paper are shown below:
Lowe, T., Garwood, R.J., Simonsen, T., Bradley, R.S., & Withers, P.W. 2013. Metamorphosis revealed: three dimensional imaging inside a living chrysalis. Journal of the Royal Society Interface: In press.
Left is the internal anatomy of a chrysalis of a Painted Lady butterfly one day after pupation, middle is the same individual after thirteen days, and right is the adult immediately prior to hatching from the chrysalis. If you keep an eye on the news you may see it around. In other news, the following paper has now been submitted:
Garwood, R.J. & Dunlop, J.A. In review (invited submission). The walking dead: Blender as a tool for palaeontologists. Journal of Palaeontology.
Which includes a step-by-step guide to using the open source raytracer Blender, and an anatomically accurate reconstruction of the Devonian arachnid Palaeocharinus based on fossils from the Rhynie Chert. This includes the animal's limb articulations and a video showing its likely gait. The following three papers are approaching completion and should be submitted by the summer:

Jones, F., Dunlop, J.A., Friedman, M., & Garwood, R. J. In prep. A cladistic analysis of the trigonotarbid arachnids.
Finally, we have two more new Palaeontology [online] posts since my last update. April's focusses on fossil communities and palaeoecology, whilst the article for May introduces a major fossil group: the trilobites.
I'm away on fieldwork for the second half of May, but I'm sure there will be another update upon my return.
Since last time the book on 3D reconstruction in palaeontology mentioned previously has been submitted.
Sutton, M.D., Rahman, I., & Garwood, R.J. Submitted. Techniques for Virtual Palaeontology. Wiley-Blackwell fast-track monograph.
It ended up being near 80,000 words - slightly larger than expected, but hopefully a comprehensive and useful addition to the literature for virtual palaeontology. The paper below has also been resubmitted with corrections:
Lowe, T. Garwood, R.J., Simonsen, T., Bradley, R.S., & Withers, P.W. Submitted. Metamorphosis revealed: three dimensional imaging inside a living chrysalis.
New Palaeontology [online] articles have also been posted, one for March on tree-kangaroos, and one new this month on how palaeontologists can work out what's missing from the fossil record by studying groups of living animals. Both are linked below. More papers in the works, so hopefully another update soon.
I've not updated the website for a couple of months, largely because I've been very busy since December! Much of my time has been spent writing 18,000 words on X-ray techniques for a forthcoming Wiley-Blackwell fast-track monograph in Earth Science:
Sutton, M.D., Garwood, R.J. & Rahman, I. Invited submission. Techniques for Virtual Palaeontology. Wiley-Blackwell fast-track monograph.
My work for this is now complete, and the following paper has also just been submitted:
Lowe, T. Garwood, R.J., Simonsen, T., Bradley, R.S., & Withers, P.W. Submitted. Metamorphosis revealed: three dimensional imaging inside a living chrysalis.
Next up is an invited paper on Blender, and then two more papers which should be completed in the near future, on insect nymphs and opilionds respectively. Following this is a foray into arachnid phylogeny and lots more exciting research. I was also part of a recent synchrotron trip to experiment with 3D chemial mapping. Hopefully this will also surface soon (and an explanation of the technique will be in the above monograph!), but in the meantime here are a couple of photos:
Naturally, there have also been new Palaeontology [online] articles for January (on life as a palaeontologist post-doc and February (on shape analysis). Links below:
While I was away at the synchrotron recently, I'm honoured to report that my 2011 Nature Communications paper on fossil harvestman was announced as the winner of Paleonturología 12, an international palaeontology competition. The announcement, in Spanish, can be found here, and press coverage of the prize here.
As part of the prize I shall be preparing a less technical account of the reseach in the near future.
A new article has been posted on Palaeontology [online] about open access in science, and the impact of the internet on the field. Interested? Read on...

The paper below appeared in PLoS one today:
Garwood, R.J., Ross, A., Sotty, D., Chabard, D., Charbonnier, S., Sutton, M. & Withers, P. 2012. Tomographic Reconstruction of Neopterous Carboniferous Insect Nymphs. PLoS one 7(9):e45779. doi:10.1371/journal.pone.0045779
The paper is based on our work using X-ray micro-tomography to create 3D models of two Palaeozoic juvenile insects. The detail the technqiue provided has allowed us to say something about their biology, and their mode of life. It was harder to work out which groups they may belong to - but we've tried! The paper is freely available from the website, so please do check it out. You can find more accessible information in this Nature news piece.
A new paper I was lucky enough to be involved in has appeared in press at PNAS. Details and link (to both paper and news coverage), in addition to picture of the beautiful fossil, are below.
