The early evolution of dinosaurs

This was originally posted at: http://blogs.egu.eu/palaeoblog/?p=581 Dinosaurs. What springs to mind when they’re mentioned? Colossal, towering sauropods? Packs of feisty feathered fiends? Or huge herds of hadrosaurs, chomping their way across the plains of long-lost worlds? Most, including myself, will automatically default to any one of these images when dinosaurs come up in conversation (what, you […]

Feeding at both ends of the food chain

In terrestrial environments, predator body size is largely correlated with prey body size. The opposite is found for many predators in the marine environment – baleen whales in particular comprise some of the world’s largest mammals and yet they feed on something far smaller (plankton). The leopard seal is unusual in that it feeds both […]

More sedimentology than you can shake a stick at

This was originally posted at: http://blogs.egu.eu/palaeoblog/?p=549 Welcome to Day 3 of the EGU Annual Meeting. Do check the Geology for Global Development page too for some cracking updates on the sessions, particularly on the more ‘applied’ side of the geosciences, by Rosalie Testovin. This post is a quick break-down of some cool science from the morning […]

From impact factors to impact craters

This was originally posted at: http://blogs.egu.eu/palaeoblog/?p=542 Day 2 in the Big Brother house (aka the European Geosciences Union General Meeting). There’s no where near enough beer, and tensions are getting high. A horde of angry horses have invaded the lower levels, and taken the President of Austria hostage, with demands of lowering the Fair Straw Tax. […]

Curiosity continues to rock on Mars

This was originally posted at: http://blogs.egu.eu/palaeoblog/?p=529 NASA might be having a rain-check on its outreach activities, but that’s not why Curiosity has gone silent the last few days. Every once in a while an event known as the Mars Solar Conjunction places Mars’ orbit directly behind the sun with respect to Earth, and makes communications impossible. […]

Dwarf crocodiles in Munich

This was originally posted at: http://blogs.egu.eu/palaeoblog/2013/04/04/dwarf-crocodiles-in-munich/ My PhD consists of two parts. The first is investigating the dynamics of biodiversity across the Jurassic/Cretaceous interval about 145 million years ago. I want to see if when we consider the biases of the fossil record whether there was a ‘hidden’ mass extinction, and what were the ecological, physiological […]
