If you go to an average Thai island today, you find a very different “predator” to what existed 100 million years ago during the Cretaceous period. Instead of your average-IQ’d Australian male ‘gap yah’ backpacker, back in the age of dinosaurs there existed a group of ferocious carnivores called megaraptorans. Source: Mega-raptors were top predators […]
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 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 my new blog at: http://blogs.egu.eu/palaeoblog/2013/03/18/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 […]
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 […]
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 […]
What comes to your mind when someone says ‘theropod dinosaurs’ to you? Does the mind conjour images of Tyrannosaurus rex noshing on lawyers, packs of voracious Deinonychus ambushing unsuspecting ornithopods, or perhaps you’re quite progressive and thought about flocks of birds migrating south for the winter. Sticking strictly to the Mesozoic (before 65.5 million years […]
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 […]
