Our world was once dominated by dinosaurs but why did they become extinct? What ultimately destroyed the final dinosaurs that had ruled the earth for 160 million years? Through recreations using cutting edge 3D computer-generated imagery, 'Last Day of the Dinosaurs' shows why time eventually ran out for them. Follow this most dramatic event in Earth's history and witness the catastrophic impact a six mile wide meteor had as it landed in the Gulf of Mexico. See how our planet was thrown into chaos with dust clouds, fire storms, earthquakes, volcanic eruptions, sand storms, mega tsunamis, acid rain and toxic gases. Learn how a lack of sunlight killed off plants and without the plants, all the herbivorous dinosaurs died, and without the plant-eaters, all the carnivorous dinosaurs died. Despite this dreadful series of events, some species managed to survive. Eventually a new order of mammals was established and man came to be dominant.
