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 […]
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 […]
When people discuss innovation and cutting-edge research in science, Palaeontology, and specifically dinosaurs, will hardly be the first thing that springs to mind, especially in times of the Large Hadron Collider, nanotechnology, and stem cell research. But in terms of actual progress, considering that dinosaurs have only existed in science and the eyes of the […]
Cretaceous Research is a journal published by the notorious for-profit publisher Elsevier (see articles on this blog). Tonight however, they have blessed us with a wealth of new research through their RSS feed (albeit, paywalled for the 99%), a lot including everyone’s favourite vertebrates, the dinosaurs. This is an inordinate amount of publications for K-Research […]
The time of digital technology is upon us. No scientific domain is embracing it’s fast-paced and dynamic progression more so than Palaeontology. One such realm that is exploding with new studies and enrapturing the minds of people and the global media is the increasing possibility to digitise and manipulate three-dimensional fossils. Surface laser-scanning, C-T scanning […]
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 […]
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 […]
What do we currently understand by a ‘species’? Naming species, also known as alpha taxonomy, forms the fundamental basis and core of systematic analysis (e.g., for biodiversity, macroevolutionary and ecological studies). Since the origin of the species concept, there has been heated and continuous debate as to what exactly constitutes a species. The discovery of […]
