Dinosaurs of a feather?

July 1, 2013

Feathered dinosaurs might not still be the new boys in town in the fossil world, but there’s still a tonne of cool research being done on them. One of the main fields is trying to figure out if different species were capable of powered flight, like in most modern birds. The recent finding of Aurornis xui appears to have confined the ability to fly just to a single feathered lineage, the one leading to modern birds, but how do we figure out whether they could fly or not?

How did birds get their wings?

June 27, 2013

How many fingers do you have? Hopefully, 5. Do you think that’s the normal condition for all animals? Do you think that’s air you’re breathing right now? … OK, so I watched the Matrix last night, but still, do you think all tetrapods (dudes with 4 feet, including you, and anything else with four flippers, wings, or feet) have 5 digits on each limb? Actually, there’s a pattern within tetrapods of limb reduction in various lineages – our earliest ancestors seemed to experiment with digit numbers and went a bit berserk by growing extra fingers from their fishy flippers.

Progressive Palaeontology, Leeds 2013

June 3, 2013

Progressive Palaeontology (ProgPal) is an annual event where early career researchers get to demonstrate their research to an equivalent audience in a reasonably informal atmosphere. It’s also renowned as a mega p*ss-up, as everyone knows palaeontologists are chronic alcoholics (hence the dinosaurs with feathers hypothesis). This year, it was in the vibrant and cosmopolitan northern UK city of Leeds. Some of the research communicated there was pretty freaking sweet. You can find recordings of all of the talks on Palaeocast (at some point in the future), and the Twitter feed was #progpal if you want to see a historical live version of the event.

Conservation biology – let’s get integrated!

May 14, 2013

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.
