25 year chap who recently earned his PhD trying to make his way into the murky, uncertain world of vertebrate palaeontology.

Updated version of this old picture featuring two males Cryolophosaurus fighting, I've mainly reworked the background. The heads should be less massive but I decided to keep it like it is. Certainly a new picture to come of one of my favourite theropod one day.

Many fossilized dinosaurs have been found in a twisted posture. Scientists have long interpreted this as a sign of death spasms. Two researchers from Basel and Mainz now come to the conclusion that this bizarre deformations occurred only during the decomposition of dead dinosaurs.

Palaeontologists and engineers at Drexel University have teamed up to scan fossilised dinosaur bones, 3D-print scaled-down replicas and then use them to build perfectly-proportioned robotic dinosaur skeletons.

A nest full of dinosaur babies—fossilized in their "last, bug-eyed, terrified minutes"—suggests Protoceratops parents nurtured their young.

What makes Pleo, the long-awaited toy dino from Ugobe, able to respond to its surroundings and learn from its environment? We take a look at his high-tech innards to see

It's been a while since I shared origami dinosaurs here. Enough time for a lot of new photos to be posted at the origami groups I follow at Flickr.

Meet the Smithsonian's Matthew Carrano, curator of Dinosauria at the Smithsonian's National Museum of Natural History in Washington, D.C. Matthew studies all things dinosaur, but focuses on the evolutionary history of predatory (meat eating) dinosaurs.

The latest issue of Science contains a paper by McKellar et al, showing a number of examples of dinosaur and early bird feathers preserved in late Cretaceous amber (about 70 million years old) from Alberta, Canada (h/t to artist Kalliope Monoyios at Symbiartic for calling to to my attention).

The first dinosaurs were small, meat-eating animal that first arose over 200 million years ago. From such small beginnings evolved thousands of different species, including the largest animals ever to walk on Earth.
