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 …[Read More]
Green Tea and Velociraptors
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 …[Read More]
Your track or mine?
How do you tell between different dinosaurs, when you don’t have any dinosaurs? Trace fossils, like footprints, are ghosts of dinosaurs past, remnants of life entombed within the rocks. Palaeontologists and ichnologists (scientists who study trace fossils, not fish) often used to get confused by the question of matching a dinosaur track to its maker. …[Read More]
It’s just a flesh wound!
Fossils, as we typically think about them, tell us about the death of an animal. The teeth, bones, shells, fragmented pseudopods and other weird and wonderful bits of carcass all only ever reflect one thing: a permanent geological limbo. These types of fossil are known as body fossils. The other major group of fossils, that …[Read More]
Dinosaur cells identified with possible dino-DNA!
The discovery of extractable dinosaur DNA is many a scientist’s dream. The idea of finding DNA within extinct animals has an air of mystery and discovery that is just ridiculously appealing, whether you’re 5, 50, a teacher, palaeontologist, or cab driver. I think this is part of human nature, where we always seem to have …[Read More]
Theropod dinosaurs were waaay more diverse than previously thought
Dinosaurs! What image sprang to your mind then? There’s a reasonable chance, I’d hazard, that your brain just conjured an image of ferocious Tyrannosaurus rex, a nimble and intelligent Velociraptor mongoliensis, or any one of the other meat-eating theropods, notoriously infamous thanks to a certain eccentric millionaire with a passion for splicing genes. These two …[Read More]
Gender confusion in Confuciusornis? Not any more!
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 …[Read More]
A new feathered dinosaur – worth getting ruffled for?
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 …[Read More]
DINOSAUR! But what does it mean..?
Palaeontology probably isn’t the most difficult of sciences, but it does incorporate aspects of chemistry, biology, and physics to a certain degree, as with many other geoscientific disciplines. Palaeontologists are also well known for the mysterious and unintelligible ‘science-speak’ that they use in research papers, fueled by this combination of a multitude of various sciences, …[Read More]
Which direction to take!?
One of the most important things palaeontologists and taxonomists do is the description of new species or fossils. Focussing on dinosaurs, because they’re the ones I know the best, there is a whole host of descriptive anatomy to get your head around. It’s not just the names of the bones; it’s also the names of …[Read More]
