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 […]
This originally appeared at: http://blogs.egu.eu/palaeoblog/?p=1152 Last night, I was honoured to have spoken at the final evening lecture at the Cambridge Science Festival, along with Nick Crumpton, Anjali Goswami, Rob Asher, and Stephanie Pierce, about why palaeontology is important. Below is a rough transcript of some of what my talk was about. Unlike the others, I […]
This was originally posted at: http://blogs.egu.eu/palaeoblog/?p=942 So I don’t normally blog whenever a new dinosaur pops out the pages, but a new one, Acheroraptor temertyorum received quite a welcome back to the living world with this exquisite illustration by Danielle Dufault. I’ve asked for her permission to post on here, and it’ll appear on the front cover […]
This was originally posted at: http://blogs.egu.eu/palaeoblog/?p=690 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. […]
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 […]
Childhood memories of dinosaurs have received another shattering blow today. The latest culprit is Yutyrannus huali, a large basal tyrannosauroid from the lower Cretaceous of China, complete with elongate integumental filament structures, or ‘protofeathers’. The etymology is quite special, says lead author Xing Xu, translating into a blend of Mandarin and Latin as ‘beautiful feathered […]
Not surprisingly, the latest Archaeopteryx study has kicked up quite a stir within the media and scientific realms, considering the iconic status it has attained since discovery some 150 years past. This latest paper by Carney et al. and published in the journal Nature Communications claims to have resolved the plumage colour of a feather […]
