The Mesozoic Era saw the spectacular rise and fall of many groups, particularly in terrestrial vertebrates. These include birds, squamates, crocodiles, and pterosaurs, who wove a complex tapestry of evolution through the 185 million years of the Mesozoic, some even persisting until now. Dave Hone, now of Queen Mary in London, has extensively studied the ecology of many of these now-extinct organisms, especially theropod dinosaurs, to gain rare insights into how they would have lived millions of years ago. You can keep track of his research by following his blogs at the Guardian and Archosaur Musings webpages.
