The Burgess Shale Formation in the Rocky Mountains of British Columbia, Canada, is one of the world's most celebrated fossil fields. It is famous for the exceptional preservation quality of its fossils which are more than 500 million years old. The rock unit of the fossil bed is black shale, exposed at the surface of the earth in many places within the Yoho National Park, where the formation is located.
Sinornithosaurus (derived fro a combination of Latin and Greek, meaning "Chinese bird-lizard") is a genus of bird-like feathered dinosaur that lived in the Early Cretaceous, about 125 million years ago.
Xiphactinus ( from Latin and Greek for "sword ray" ) is an extinct genus of large marine predary fish that existed in the late Cretaceous Period, between 99 and 65 million years ago.
Corythosaurus (meaning "helmet-lizard) was a large, plant-eating, duck-billed dinosaur that lived in the Cretaceous Period, 80 - 65 million years ago. It was 9-10 m long, 2 m tall at the hips, and weighed about 5 tons.
Helicoprion is a genus of shark-like, spiral-toothed prehistoric fish that arose in the early Permian, about 290 million years ago, survived the Permian-Triassic extinction event, and eventually became extinct during the early Triassic, some 250 million years ago.
Chasmosaurus is a genus of beaked, plant-eating dinosaurs that lived during the Upper Cretaceous Period, between 76 - 70 million years ago. The name means "opening lizard", referring to large openings in its frill.
Peteinosaurus ("winged lizard") is a genus of extinct feathered reptiles that existed in the Later Triassic period, between 221 - 210 million years ago. With a wingspan of around 60 cm and weight probably less than a common blackbird, it was one of the smallest flying reptiles in its day. Its wings consisted of skin stretched between an elongated finger on its hand, and its foot.
The Jurassic is a geologic period that extends from 201 million to 145 million years ago, from the end of the Triassic to the beginning of the Cretaceous. The Jurassic constitutes the middle period of the Mesozoic Era, also known as the Age of Reptiles. It is named after the Jura mountains on the border between Switzerland and France, where rocks of this age were first studied.
Hylaeosaurus ( meaning "woodland lizard" ) was an armored four-legged plant-eating dinosaur that lived in the early Cretaceous Period, about 135 - 119 million years ago.
Struthiomimus ("ostrich mimic", the name derived from Greek "strutheios" meaning 'of the ostrich' and "mimos" meaning 'imitator') is a genus of omnivorous bird-like dinosaurs, bearing a superficial resemblance to modern ostriches, that lived in the late Cretaceous period, 80 - 66 million years ago.
