An interesting step for open access..

Jon Tennant November 18, 2013

If you haven’t heard of it yet, a new tool, the Open Access Button has just launched, coincident with a large open access conference in Berlin. Below is a copy of their press release, the original of which can be found here. In the mean time, check out some of the EGU’s open access journals – there’s quite a decent variety! Also, for those interested, the Finch Committee who kicked off open access policy development in the UK just released a review of their progress, which is worth a peek.

Students Launch “Button” to Put Denied Access to Research on the Map

BERLIN – Today, at an international meeting of student advocates for expanded access to academic research, two undergraduates from Great Britain announced the highly-anticipated launch of The Open Access Button – a browser-based tool to map the epidemic of denied access to academic research articles, and help users find the research they need.

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

Jon Tennant November 18, 2013

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.

A double-whammy of dinosaur awesomeness. Pun totally intended.

Jon Tennant November 13, 2013

This is a post about pachycephalosaurs. It’s not a post about feathered dinosaurs, huge dinosaurs, or any of the ones which you may be more familiar with from popular media. Pachycephalosaurs were the dome-headed little scrappers of the Cretaceous, around 85 to 66 million years ago. Their name means ‘thick-skulled lizard’ (pachy: thick, cephalon: skull, saurus: lizard), and they were a small group within the larger herbivorous group of dinosaurs called ornithischians.

It’s probably fair to say that these dinosaurs are one of the least popular groups; they didn’t have razor sharp teeth and sickle-switchblade claws, they didn’t grow to the size of houses, and they didn’t have rows of armoured shields and spikes along their backs. What they did have, however, is an unusual behaviour that signifies them as unique, and pretty amazing, beasties.

SVP Day 3

Jon Tennant November 2, 2013

OK, day 3, still alive.

The first session this morning was on saurischians dinosaurs, the major group that includes sauropods and theropods.

My supervisor, Phil Mannion, was the first talk I was awake enough for (*cough*), and gave us a run-through of sauropods from the infamous Late Jurassic (~150 million years old) Tendaguru formation from Tanzania. With new revisions, the sauropod fauna from here are remarkably similar in terms of higher taxa to sites known from Iberia, China, and the US, although only somphospondylans, a quite advanced group, are known from Tendaguru.
