This was originally posted here. 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 …[Read More]

The early evolution of birds – more complicated than trying to untangle your headphones..
Birds are a phenomenal story of evolutionary success. As modern-day dinosaur descendants, they occupy almost all environments and ecosystems around the globe, and are truly animals that capture our imaginations. However, how did they become so diverse, both in number and form? This is something only the fossil record can divine for us. Birds first …[Read More]
IPC4 Day 1 – Using the past to inform the present
Welcome to the fourth International Palaeontology Congress! 900 palaeontologists have piled into the land of steak, sun, and malbec in Mendoza, Argentina, for the biggest palaeontology conference that draws from all parts of the field. What I want to do with these posts is just provide snapshot summaries of the talks I’ve been at to …[Read More]
Last dinosaur of its kind found in the land that time forgot
In terms of iconic dinosaurs, the gargantuan sauropods are certainly up there. Along with the mostly meat eating-theropods, and herbivorous and often armoured ornithischians, they form one of the three major groups, or clades, of dinosaurs, and were the biggest animals to ever walk this Earth. The end of the Jurassic period, some 145 million …[Read More]
Where did all the mammoths go?
Let’s go meta. Recently, ecologist extraordinaire Dr. Jacquelyn Gill (or is it Professor cos of that weird American system?) wrote a wonderful review article on the extinctions that affected many large mammal species during the last 50-10,000 years. This period is known as the Quaternary, and was a time when ice ages were running rife …[Read More]
Was the diversity of feeding styles in giant turtles a key to their suckcess?
Sometimes, it can be difficult to figure out how ancient organisms used to eat. Part of the problem is that we can never actually see extinct animals eating (until we invent time-travel.. *taps fingers impatiently at physicists*), and often it can be hard to work out how something ate based just on its anatomy. Sometimes …[Read More]
The early evolution of dinosaurs
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 mean it’s not that frequent …[Read More]
Plan of action!
Crikey, it’s been 3 months already?! *panics* At Imperial College, new PhD students have to produce an initial plan of study within the first three months of setting off, and submit it for independent assessment. Having uploaded mine just now (not in the slightest bit late..), I figured I’d share it here! It’s a broad …[Read More]
