This was originally posted at: http://blogs.egu.eu/palaeoblog/?p=466 How can the dead help the living? This is a question a lot of fossil-fanatics have bent a lot of time towards over recent years, partially due to a desire to make palaeontology ‘relevant’ as a modern science, and secondly to help guide our efforts in conservation biology. A new […]
This was originally posted at: http://blogs.egu.eu/palaeoblog/2013/03/20/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 […]
Among the many issues with the fossil record is the case of gender identification. In modern organisms, it is usually pretty easy to tell which members of a particular species are the males and which are the females. This can either be through consistently perving on them to figure it out during copulation, or some […]
Two new feathered dinosaur articles appeared in the latest edition of Nature Communications; one on gender identification in a well-known theropod (the meat noshing ones), and the subject of a forthcoming blog post, and another on a new feathered fiend from, surprise surprise, China. I normally really don’t like writing about theropods, especially of the feathered […]
The fossil record is brutally frustrating; it mostly preserves only vestiges of deaths long past as body fossils, with occasional glimpses of life being gleaned from their surroundings and any trace fossils, or activity fossils that we might find. One question palaeontologists have long been seeking the answer for is how good were dinosaurs as […]
Archaeopteryx lithogaphica is probably the most iconic dinosaur ever. When it was first discovered, it was heralded as the holy grail of palaeontological findings, as it helped to consolidate the evolutionary continuum between theropod dinosaurs and modern birds. What it also represents though, is an example of the evolution of scientific thought through time. Palaeontologists, […]
This is a slightly different post to the usual, you know, fossils and shit. It concerns the psychology behind climate change and mobilising towards a green future. Now this is by no means my area of expertise, but when I attended a talk recently by Oliver James at The Photographers’ Gallery in London, entitled “Our […]
The story of vertebrate evolution over the last 250 million years is one of the most remarkable, and most complex to unravel, stories of all time. Throughout the ages, extraordinary species and groups have come and gone, and we are left now with only a fingerprint of times long forgotten. Recreating and detecting macroevolutionary patterns […]
Recently, a really important paper by Alex Dunhill of Bristol University, UK, (@AlexDunhill on Twitter) has been published looking at the problems of using rock outcrop area as a sampling proxy for understanding patterns of biodiversity in deep geological time. What this paper highlights is the important distinction between geological and anthropological sampling proxies, and […]
Disclaimer: Apparently Carlsberg don’t write my titles.. Back in May 2011, a study was published in Science describing the application of sclerotic ring and orbital morphology in determining daily activity (diel) patterns in extinct archosaurs. Recently, a comment and counter-comment have been published, both with pretty critical rhetoric. I figured that as it appears to […]
