Albertaceratops
Albertaceratops was a centrosaurine horned dinosaur that lived during the middle Campanian age of the Late Cretaceous period in what is now Alberta, Canada. It is distinguished by its unique combination of long brow horns and a bony ridge over its nose, along with large, outwardly-projecting hooks on its frill. This dinosaur is estimated to have reached lengths of up to 5.8 meters and weighed around 3,500 kilograms.

About Albertaceratops
Albertaceratops is a genus of centrosaurine horned dinosaur that roamed the Earth during the middle Campanian age of the Late Cretaceous period. Its fossils were discovered in the Oldman Formation of Alberta, Canada. The meaning of its name, "Alberta horned face," directly references its place of discovery and its striking cranial ornamentation.
Description and Discovery
Albertaceratops is notable for its unusual combination of features within the centrosaurine group. While most centrosaurines possess short brow horns, Albertaceratops sported long ones. Its face was further characterized by a bony ridge above the nose and two prominent, outwardly-projecting hooks on its frill. These distinctive traits, along with its estimated size of 5.8 meters (19 feet) and weight of 3,500 kilograms (7,700 lb), make it a unique find.
The discovery of Albertaceratops is based on a single complete skull and additional postcranial fragments. Its describer, Michael J. Ryan, identified it as the most basal centrosaurine discovered to date. While initial reports suggested the presence of Albertaceratops remains in Montana's Judith River Formation, subsequent studies indicated these belonged to a different centrosaurine, Medusaceratops. Both dinosaurs lived concurrently, around 77.5 million years ago.
The species name, A. nesmoi, was chosen to honor Cecil Nesmo, a rancher from Alberta whose efforts aided fossil hunters. This recognition highlights the collaborative nature of paleontological discovery and the importance of local support.

Related Dinosaur species
Anchiceratops
Anchiceratops is an extinct genus of chasmosaurine ceratopsid dinosaur that roamed what is now Alberta, Canada, during the Late Cretaceous Period, approximately 73 to 68 million years ago. This heavily built, quadrupedal herbivore was characterized by a distinctive skull featuring two long brow horns, a short nasal horn, and an elongated, rectangular frill with ornate, triangular projections along its edges. The genus name "Anchiceratops" translates to "near horned face," reflecting its perceived evolutionary relationship to other ceratopsids.
Anodontosaurus
Anodontosaurus was a medium-sized ankylosaurid dinosaur that lived during the Late Cretaceous period in what is now Alberta, Canada. This armored herbivore is known for its distinctive tail club and skull ornamentation, distinguishing it from closely related ankylosaurs.
Centrosaurus
Centrosaurus is a genus of dinosaur belonging to the Centrosaurinae subfamily, known for its characteristic nasal horn and frill ornamentation. These large herbivores lived during the Campanian age of the Late Cretaceous period in what is now Canada. Vast bonebeds suggest they were gregarious animals that may have traveled in herds.
