While dinosaurs may have been some of the mightiest creatures ever to have walked the earth, they also could have been among the most bizarre. With extreme, exaggerated body parts, some predators were loaded with outlandish or disproportionately sized appendages. Join world-renowned paleontologists and travel the globe to unearth some of the lesser-known but most surprising members of the dinosaur family: Mamenchisaurus, whose neck alone was longer than the rest of its body; Chasmosaurus, adorned with a fashionable crown of frilly spikes to attract the eyes of potential suitors; Spinosaurus, with massive extensions from its vertebrae that could have supported a sail or a hump; and Parasaurolophus, whose tube-like head crest may look odd to us, but was a mating magnet back in the day.

The Pit of Death is what some scientists are calling it, others "Dinosaur Pompeii". Envision dinosaur corpses stacked one on top of each other, piled four and five high. But not just any old dinosaurs, new, well-preserved skeletons - many that have never been seen before. A bizarre T. rex ancestor, a triceratops ancestor, an ancient crocodilian and nearly 40 different species dating back 160 million years, a time in dinosaur history of which little is known. The graves of these new species are uncovered deep in the dry and desolate Junggar Basin of western China and a team of palaeontologists unearth answers to this virtual black hole in dinosaur evolution. Watch as the bones are examined, reconstructed and brought back to life, using high resolution CGI, and slowly probe the mystery of who these dinosaurs were, how they died and what they can tell us about the Lost Age of the Dinosaurs.
