Pachyrhinosaurus
Click here for more Pachyrhinosaurus Pictures
Pachyrhinosaurus was a herbivore (plant-eater) that lived in western North America
during the late
Cretaceous period,
between about 72 and 68 million years ago. Its
fossils
have been found in
Alberta, Canada,
and in Alaska.
Pachyrhinosaurus was about 18 feet (5.5 meters) long, and weighed about
4 tons. Like other
Ceratopsian dinosaurs,
it had a massive head, a neck-frill, and spikes on its neck-frill. However, unlike some of its relatives
it did not have a horn on its snout, but instead had a massive flattened bony lump ("boss").
Scientists believe that it probably
used this boss in butting and shoving matches in a similar way to musk oxen do today.

Click Here | Product Description: 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. |

Click Here | Product Description:
The horned dinosaurs, a group of rhinoceros-like creatures that lived 100 to 65 million years ago, included one of the greatest and most popular dinosaurs studied today: Triceratops. Noted for his flamboyant appearance--marked by a striking array of horns over the nose and eyes, a long bony frill at the back of the head, and an assortment of lumps and bumps for attracting females--this herbivore displayed remarkable strength in its ability to fight off Tyrannosaurus rex. It was also among the last dinosaurs to walk the earth. In telling us about Triceratops and its relatives, the Ceratopsia, Peter Dodson here re-creates the sense of adventure enjoyed by so many scientists who have studied them since their discovery in the mid-nineteenth century. From the badlands of the Red Deer River in Alberta to the Gobi Desert, Dodson pieces together fossil evidence to describe the ceratopsians themselves--their anatomy, biology, and geography--and he evokes the human dimension of their discovery and interpretation. An authoritative survey filled with many original illustrations, this book is the first comprehensive presentation of horned dinosaurs for the general reader. Dodson explains first the fascinating ways in which the ceratopsians dealt with their dangerous environment. There follows a lesson on ceratopsian bone structure, which enables the reader quickly to grasp the questions that still puzzle scientists, concerning features such as posture, gait, footprints, and diet. Dodson evenhandedly discusses controversies that continue, for example, over sexual dimorphism and the causes of the dinosaurs' disappearance. Throughout his narrative, we are reminded that dinosaur study is a human enterprise. We meet the scientists who charmed New York high society into financing expeditions to Mongolia, home of Triceratops' predecessors, as well as those who used their poker winnings to sustain paleontology expeditions. Rich in fossil lore and in tales of adventure, the world of the Ceratopsia is presented here for specialists and general readers alike. |
