Palaeontology

The underworld thief returns from the dead

So I don’t normally blog whenever a new dinosaur pops out the pages, but a new one, Acheroraptor temertyorum received quite a welcome back to the living world with this exquisite illustration by Danielle Dufault. I’ve asked for her permission to post on here, and it’ll appear on the front cover of Naturwissenschaften (December issue, probably), so defo worth checking out a hard copy!

Acheroraptor, in all its glory

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.

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.

Was the diversity of feeding styles in giant turtles a key to their suckcess?

­Sometimes, it can be difficult to figure out how ancient organisms used to eat. Part of the problem is that we can never actually see extinct animals eating (until we invent time-travel.. *taps fingers impatiently at physicists*), and often it can be hard to work out how something ate based just on its anatomy.  Sometimes though, the fossil record chucks up something truly spectacular, and gives us amazing insight into the spectacular diversity of ancient life.

Let’s roll it back a bit.
