Euoplocephalus

Euoplocephalus is a genus of armored ankylosaurid dinosaur known from Late Cretaceous North America. Its body was protected by extensive bony armor, and its tail ended in a club.

Ankylosauridae: Ankylosauridae is a family of herbivorous ankylosaurs with heavily armored bodies and, in many species, tail clubs. Euoplocephalus is classified within this family of armored dinosaurs.
Euoplocephalus tutus: Euoplocephalus tutus is the type species of the ankylosaurid dinosaur genus Euoplocephalus. This species anchors the name and classification of the genus.
Lawrence Lambe: Lawrence Lambe was a Canadian geologist and paleontologist who studied and named many fossil vertebrates. Lambe named Euoplocephalus in 1910 from fossils found in Alberta.
Dinosaur armor: Dinosaur armor comprises bony or horn-covered structures that protected the bodies of some dinosaur groups. Euoplocephalus provides extensive fossil evidence for armor design in dinosaurs.
Ankylosauria: Ankylosauria is a group of herbivorous dinosaurs characterized by broad bodies and extensive protective armor. This broader group includes ankylosaurids as well as their close relatives.
Dinosaur Provincial Park: Dinosaur Provincial Park is a fossil-rich protected area in Alberta, Canada, known for Late Cretaceous dinosaur remains. Its fossil beds have yielded important remains assigned to Euoplocephalus.
Canadian Museum of Nature: The Canadian Museum of Nature is a national natural history museum in Ottawa, Canada. Its fossil collections include material central to the study of Euoplocephalus.
Biomechanics: Biomechanics applies mechanical principles to the structure and movement of living and extinct organisms. Mechanical analysis helps estimate the forces Euoplocephalus’s tail club could deliver.
Osteoderm: An osteoderm is a bony structure that forms within the skin of an animal. Osteoderms formed the plates and other elements of Euoplocephalus’s armor.
Dinosaur Park Formation: The Dinosaur Park Formation is a Late Cretaceous rock formation in Alberta, Canada, rich in dinosaur fossils. Fossils from this formation document Euoplocephalus in its ancient ecosystem.
