Achelousaurus horneri skull, collected in Glacier County, Montana, at the Museum of the Rockies in Bozeman, Montana.
The Ceratopsidae are those dinosaurs with head frills.  There are three large subgroups of Ceratopsidae: Centrosaurinae, Ceratopsinae, and Chasmosaurinae. The Triceratopsini are a "tribe" of the Chasmosaurinae -- a genus so vast that it gets the special name "tribe".  The Pachyrhinosaurini are a "tribe" within the Centrosaurinae.

Achelousaurus is a genus within the Pachyrhinosaurini.  So far, only three skulls and some limited skeletal remains have been collected anywhere in the world -- and all of them in Montana.  Their bony frills are quite similar to the Styracosaurus albertensis, although their other skull features (such as big bony bosses on the nose and behind the eyes) are not.

Cast of a Scaphognathus crassirostris, a kind of pterosaur. On display as part of the exhibit "Pterosaurs: Flight in the Age of Dinosaurs" at the Cleveland Natural History Museum in Cleveland, Ohio, in the United States.
This animal lived about 150 million years ago. This fossil was found in the Solnhofen formation in Germany. This is a cast; the fossil itself is held by the Institute of Geology and Paleontology at the University of Bonn.

Montanoceratops cerorhynchus (Brown & Schlaikjer, 1942) - fossil ceratopsian dinosaur skeleton from the Cretaceous of Montana, USA. (MOR 542, Museum of the Rockies, Bozeman, Montana, USA)
The species name is sometimes incorrectly spelled "cerorhynchos".  The original publication spells it "cerorhynchus".  The genus name is sometimes incorrectly spelled "Montanaceratops".
Ceratopsians are the "horned dinosaurs".  They were large, quadrupedal, herbivorous dinosaurs having a beaked skull and a frill - an extension of bone behind the skull that partially covered the neck.  Ceratopsian dinosaurs are known from the Jurassic and Cretaceous.  The last members of the group died out at the Cretaceous-Tertiary boundary, 65 million years ago.
This is a partial skeleton of a juvenile Montanoceratops, a ceratopsian from the near-latest Cretaceous of western North America.  This type of ceratopsian lacked facial horns.


From exhibit signage:
Sixty-eight million years ago, when the horned dinosaurs Triceratops and Torosaurus inhabited the coastal plain near the inland ocean, primitive "horned" dinosaurs named Montanoceratops lived in uplands near the young Rocky Mountains.  These little protoceratopsians fed on plants with slicing teeth and narrow beaks similar to their giant three-horned relatives.


Classification: Animalia, Chordata, Vertebrata, Reptilia, Archosauria, Dinosauria, Ornithischia, Marginocephalia, Ceratopsia, Leptoceratopsidae
Stratigraphy: St. Mary River Formation, Maastrichtian Stage, Upper Cretaceous
Locality: Little Rocky Coulee, north of the town of Cut Bank, eastern Glacier County, northwestern Montana, USA

 Cette semaine, nous allons découvrir un premier dinosaure au look unique avec un nom très cool.  Rencontrez Daemonosaurus chaoliodus ! Daemonosaurus était un petit dinosaure carnivore qui vivait dans ce qui est aujourd'hui le Nouveau-Mexique, aux États-Unis, à la fin du Trias, il y a environ 205 à 200 millions d'années.  Du nez à la queue, on estime qu'il mesurait environ 5 à 7 pieds (1,5 à 2,2 m).  Il s’agit d’estimations basées sur le fait que seuls le crâne et le cou ont été retrouvés.  Le nom du genre se traduit par "Demo
