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.
The early evolution of dinosaurs
Dinosaurs. What springs to mind when they’re mentioned? Colossal, towering sauropods? Packs of feisty feathered fiends? Or huge herds of hadrosaurs, chomping their way across the plains of long-lost worlds? Most, including myself, will automatically default to any one of these images when dinosaurs come up in conversation (what, you mean it’s not that frequent for normal people?) But we often neglect to think the earliest dinosaurs, spectacular organisms that gave birth to the most successful, and on-going, terrestrial vertebrate radiation of all time.
Slicing up dinosaur embryos. For science.
Birds are living, breathing, tweeting dinosaurs. That is scientific knowledge backed up by overwhelming evidence, but the evidence basis for it grows strong all the time. We know that they are related from a host of morphological evidence from the last 150 million years or so. Our understanding of the origins of feathers and flight are developing too – each new finding is a piece that slots into a puzzle, where we already have a pretty good idea of what the picture we’re trying to recreate is. The evidence is mounting too with each new discovery – findings from China are rewriting the way we think about the evolution of feathers and flight, and the evolution of early birds from their dinosaurian ancestors.
Fly, my pretties, fly!
The origin of bird flight is one of the greatest stories evolution has ever told us in the history of life on this planet. To imagine how organisms that once ran around on the ground have descendants that soar through the skies is truly phenomenal, and represents a truly great leap in increasing the awesomeness of these animals. The secret of how it came about though is hidden away in the fossil record, with the mysterious tale ever-shifting as our understanding of early birds and feather precursors evolved.
