The Rise and Fall of the Dinosaurs: Four Surprising New Discoveries
Overview
The dinosaurs ruled the Earth for over 150 million years–evolving into spectacular giants, like Brontosaurus and T. rex. Over the last two decades, we have learned more about dinosaurs than ever before, thanks to a blistering pace of new fossil discoveries that have produced around 50 new dinosaur species per year, on average. This lecture will recount the story of where dinosaurs came from, how they rose to dominance, how most of them went extinct when a giant asteroid hit, and how some of them lived on as today’s birds. Professor Brusatte will highlight four intriguing new discoveries from his research: footprints of the oldest dinosaur antecedents from Poland; fossils of some of the first enormous dinosaurs from Scotland; new small-bodied tyrannosaur ancestors from Uzbekistan and China; and feathered and winged raptors closely related to birds from China. At a time when Homo sapiens has existed for less than 200,000 years–and we are already talking about planetary extinction–dinosaurs are a timely reminder of what humans can learn from the magnificent creatures that ruled the earth before us.
