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

Cet ancien parent du crocodile a grandi sur quatre pattes puis a marché sur deux
fossile Dinosauria
Un étrange parent d'un crocodile de l'époque des dinosaures réécrit ce que les scientifiques pensaient savoir sur les anciens reptiles. Cette créature de la taille d'un caniche, appelée Sonselasuchus cedrus, semble avoir commencé sa vie en marchant à quatre pattes avant de passer à une position sur deux pattes à mesure qu'elle grandissait - une transformation inhabituelle rarement observée dans les archives fossiles.

Ces minuscules fossiles de dinosaures ont trompé les scientifiques pendant 20 ans
armure os croissance fossile Ankylosauria Dinosauria découverte
De minuscules fossiles de dinosaures qui ont intrigué les scientifiques pendant plus de 20 ans ont enfin révélé leur véritable identité. Plutôt que d’appartenir à une espèce miniature, ce sont en réalité des bébés ankylosaures, certains âgés de moins d’un an, y compris un possible nouveau-né. En étudiant les schémas de croissance osseuse, les chercheurs ont confirmé que ces jeunes dinosaures n’étaient pas encore devenus des adultes de grande taille. La découverte apporte un nouvel éclairage sur la façon dont les ankylosaures se sont développés, montrant qu'ils ont commencé à développer une armure étonnamment tôt.

os croissance prédateur fossile juvénile Dinosauria Nanotyrannus
Un mystère de longue date sur les dinosaures pourrait enfin être résolu : Nanotyrannus, autrefois considéré comme un simple T. rex adolescent, semble avoir été une espèce distincte après tout. Les scientifiques ont analysé un minuscule os de la gorge du fossile original et ont découvert des schémas de croissance montrant que l'animal était déjà mature et non un géant juvénile en devenir. Ce petit prédateur, environ la moitié de la taille d'un T. rex adulte, errait probablement aux côtés de son célèbre cousin, ajoutant une nouvelle couche de complexité à l'écosystème préhistorique.
