Green Tea and Velociraptors

I need your clothes, your boots, and your copyright.

1456588_10151852838033299_832432892_nJames Lewis is a PhD student at Imperial College London in the field of Planetary Geochemistry. When not blowing up gas cylinders, or hunting for jarosite, he can be found wandering the streets of London as an amateur photographer. James also suffers from Thesisitis, a common condition among third-year PhD students. He can be found on Twitter as @jmtlewis.

When I was applying for PhD projects two and a half years ago I found it slightly frustrating that no one could give me a definitive description of what a PhD is like.  There was no single answer as to what the challenges would be or the timescale at which practical work and writing up would play out or what was expected of me. Now that I’ve just become a third year student I’ve come to realise that there’s a reason for this. A PhD project has so many variables: the nature of your supervisor; the department; lab work; field work; modelling, and so on. New postgraduate research students can’t be given a rigid road map for their entire project because generally in the space of a few weeks or months things will change so much that the original plans will be almost meaningless. If you’re just starting out with your project don’t let this scare you but embrace the fluidity of academic research. While it’s important not to stray too far from your core project aims some of the most interesting and publishable work comes about when people explore why something didn’t work or following up an unanswered question identified through reviewing the literature.

Theropod skulls: a note of caution

Morphometrics is a horrible word, but refers to a technique that is gaining increased traction in palaeontology in recent years. It essentially is a way of measuring anatomy, or specific aspects of anatomy. An extension of it is called geometric morphometrics, and this relies on using co-ordinate points on fossils to analyse things like shape variation.

The newly minted Dr Christian Foth had a study out earlier this year that did a kind of meta-analysis of morphometrics, using theropod skulls (the group including dinosaurs like T. rex and Troodon, as well as modern birds) as an example. A lot of research has gone into using morphometrics to look at patterns in theropod skull variation through time, as looking at these evolutionary patterns is not only awesome, but can also tell us about their ascent to success through time.

A new power is rising…

This post originally appeared at: http://the-briefing.com/a-new-power-is-rising/

People always under-estimate the power of the fossil record. There has always been this stigma surrounding it that it is too poor, or too biased to read ‘properly’, and is consequently of no use. I still hear this quite a bit, and there are a couple of reasons for it.

Over the last ten years or so, there has been a substantial increase in the methods we can use to interpret the fossil record, based on an increased understanding of the interaction between large fossil data sets, the geological record, and the way in which we as humans have sampled these archives. This has dramatically changed the way in which we think of, and use, the fossil record – we see its imperfections, but we also know how to compensate for them, making the fossil record a new rising power for understanding biological patterns in deep time.

Three-dimensions of palaeontological awesomeness

Scientific publishing is entering a new era, with digital content becoming more and more important in a world where data is openly and freely shared. In palaeontology, we’re not being left behind. Along with this shift, 3D fossils are adding a new breadth to the field, both in a scientific and educational context. A great example is the British Geological Survey’s immense 3D fossil project.

I thought it might be a nice idea to draw attention to a new article by Stephan Lautenschlager of the University of Bristol, discussing the role that 3D palaeontology has to play in the current publishing world, as well as ways of implementing it. He’s been cool enough to make the article open access (see link at the bottom), so I’d recommend heading over to check it out.
