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

Des chercheurs de Virginia Tech (Virginie, États-Unis) ont identifié une nouvelle espèce de dinosaure du Trias supérieur.  Le dinosaure a été nommé Ptychotherates bucculentus.  Ce nouveau taxon de dinosaure carnivore a été érigé sur la base de l'examen détaillé d'un fossile de crâne incomplet, bien conservé mais mélangé (numéro de spécimen CM 31368).  Le crâne provient de la Coelophysis de renommée mondiale

Le Peloroplites était un dinosaure herbivore qui vivait dans ce qui est aujourd'hui l'Utah, aux États-Unis, pendant la période du Crétacé, il y a entre 98 et 93 millions d'années.  Du museau à la queue, il mesurait environ 6 m de long.  Son nom de genre se traduit par « Hoplite géant » en référence aux hoplites, les anciens soldats grecs qui portaient des lances et de grands boucliers.  Le nom de l'espèce se traduit par « Cedar Mountain ».

prédateur musée États-Unis Dinosauria squelette
Un énorme « crocodile terroriste » de la taille d’un bus qui s’attaquait autrefois aux dinosaures a été ramené à la vie avec des détails époustouflants grâce au premier squelette complet scientifiquement précis de Deinosuchus schwimmeri. S'étendant sur plus de 9 mètres de long, cet ancien prédateur suprême régnait sur le sud-est des États-Unis il y a plus de 75 millions d'années. Les visiteurs peuvent désormais le voir de près au Tellus Science Museum, le seul endroit au monde à posséder cette réplique.
