Why I think the Jurassic/Cretaceous boundary is super important

Mass extinctions are insanely catastrophic, but important, events that punctuate the history of life on Earth. The Jurassic/Cretaceous boundary, around 145 million years ago, was originally thought of to represent a mass extinction, but has subsequently been ‘down-graded’ to a minor extinction event based on new discoveries.

However, compared to other important stratigraphic boundaries, like the end-Triassic or the end-Cretaceous, both time periods representing mass extinction events, the Jurassic/Cretaceous (J/K) boundary actually remains really poorly understood. This is both in terms of what was going on with different animal groups at the time, and what environmental changes were occurring alongside this.

Well, I have a new research paper out now that synthesises more than 600 research articles, bringing them together to try and build a single picture of what was going on around this time! It’s free to read here, and is essentially the literature review from my thesis, or as I like to think of it, the justification for my existence as a researcher!

Plotting for the Earth. Sciences.

So a cool paper came out a while back about using plots when attempting to construct stories as a mode of communicating in Earth Science. I cannot, as always, emphasise my frustration when someone writes an article that’s supposed to be broadly educational, and sticks it behind a paywall. In this case, it might have reached the target audience of practising institutionalised Earth scientists (hello), but not the many who aren’t fortunate to have a subscription.

Conservation biology – let’s get integrated!

Conserving our world’s biodiversity is currently one of the biggest challenges we face. I wrote a post recently about some of the issues palaeontologists face when trying to make our science relative to current conservation management and biodiversity issues (and have written elsewhere about this too). This is very much a developing issue within which palaeontology is framing itself, as with ever squeezing science budgets around the world, scientists are being forced to find the hook or application that makes their research ‘relevant’ to broader society. The role that palaeontology can play for both climate change and biodiversity patterns and processes is the natural progression of science accompanying such shifts.

More sedimentology than you can shake a stick at

Welcome to Day 3 of the EGU Annual Meeting. Do check the Geology for Global Development page too for some cracking updates on the sessions, particularly on the more ‘applied’ side of the geosciences, by Rosalie Testovin. This post is a quick break-down of some cool science from the morning session on the interaction between tectonics (faulting and folding from plate-related movements) and stratigraphy (the way in which rock packages are linked with each other). Naturally, I had to cover this one, as it was co-sponsored by the Geological Society of London (I’m an ex-employee), and was convened by a member of my department (Dr. Alex Whittaker) at Imperial College with another giving a talk (Prof. Phillip Allen). Here’s a quick break down of some of the talks (at least in as much detail as to be expected from a vertebrate palaeontologist):

From impact factors to impact craters

Day 2 in the Big Brother house (aka the European Geosciences Union General Meeting). There’s no where near enough beer, and tensions are getting high. A horde of angry horses have invaded the lower levels, and taken the President of Austria hostage, with demands of lowering the Fair Straw Tax.

But throughout all the acid-fuelled hysteria, two events have stuck out so far today. The first was a workshop discussion on open access publishing for early career researchers (ECRs), hosted by a new Editor for the EGU’s publishing house, Copernicus. Unfortunately, this event confirmed a lot of the current issues with the development of open access policies globally, in that there has been a serious communications breakdown about the effects the policy transitions, particularly in the UK now that Research Councils UK’s (RCUK) open access policy has come into play (April 1st), will have on how and where ECRs can publish. Here are comments on several of the more prevalent points raised:
