Max Pearson presents a collection of this week’s Witness History episodes from the BBC World Service. We hear about a prehistoric discovery in India - a nest full of dinosaur eggs found in 1982. Plus, why a Mongolian dinosaur skeleton became the centre of a 2012 court battle in a case known as United States V One Tyrannosaurus Bataar. Our guest, palaeobiologist Neil Gostling reveals how newly-uncovered dinosaurs are named, and tells us which fossilised beast was the first to be christened. José Mujica recounts his journey from young revolutionary in the 1960s and 70s to becoming Uruguay's president in 2009. Plus, we learn more about the deaf children in Nicaragua who invented their own sign language. And find out why a treehouse built beside the Berlin Wall during the Cold War became a symbol of resistance. Contributors:
