Pachyrhinosaurus: The Mystery of the Horned Dinosaur (Discoveries in Palaeontology)
Price 12.44 USD
Pachyrhinosaurus, one of the rarest, least understood horned dinosaurs, lived during the second half of the Cretaceous Period, the last period in the 150-million-year Age of Dinosaurs. Pachyrhinosaurus was different in a striking way. Instead of the sweeping lances found on fossil Triceratops and Centrosaurus faces, gnarly platforms of bone covered Pachyrhinosaurus"s nose and eyebrows. These bony fossil shields gave the dinosaur its name: Pachyrhinosaurus means "thick-nose reptile."Pachyrhinosaurus, the third book in the Royal Tyrrell Museum"s Discoveries in Palaeontology series, follows two separate stories.The first is of the discovery of Pachyrhinosaurus fossils at Pipestone Creek in northwestern Alberta. The second is the story of a single Pachyrhinosaurus herd and the events that led to its abrupt demise 76 million years ago. Each story is compellingly told and accompanied by colour illustrations throughout. The Discoveries in Palaeontology series includes Albertosaurus, which explores the life of a distant cousin of the ferocious predator Tyrannosaurus Rex, and Ornithomimus, which is about a small, toothless theropod that resembled an ostrich and is believed to have given rise to birds.
