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

Un fossile d'ambre vieux de 16 millions d'années vient de révéler la plus petite fourmi prédatrice jamais trouvée
prédateur fossile évolution extinction
Une fourmi fossilisée des Caraïbes, Basiceros enana, conservée dans de l'ambre dominicain, révèle l'ancienne aire de répartition de l'espèce et renverse les hypothèses sur l'évolution de sa taille. L’imagerie avancée montre qu’il possédait déjà les adaptations de camouflage de ses parents modernes, offrant de nouvelles perspectives sur les stratégies d’extinction et de survie.

Un poisson vieux de 400 millions d'années révèle une grave erreur dans notre compréhension de l'évolution
fossile découverte évolution
Un poisson considéré comme la capsule temporelle de l’évolution vient de surprendre les scientifiques. Une dissection détaillée du cœlacanthe – une espèce vieille de 400 millions d’années souvent appelée « fossile vivant » – a révélé que les muscles clés censés faire partie de l’évolution précoce des vertébrés étaient en réalité des ligaments mal identifiés. Cela signifie que les hypothèses fondamentales sur la façon dont les vertébrés, y compris les humains, ont évolué pour manger et respirer, devront peut-être être réécrites. La découverte corrige des décennies d'erreurs anatomiques et remodèle l'histoire de s

Un fossile vieux de 500 millions d’années vient de réécrire l’histoire de l’araignée
fossile
Il y a un demi-milliard d’années, une étrange créature marine appelée Mollisonia symetrica aurait ouvert la voie aux araignées modernes. Grâce à une analyse détaillée du cerveau des fossiles, les chercheurs ont découvert des schémas neuronaux étonnamment similaires à ceux des arachnides d'aujourd'hui, ce qui suggère que les araignées ont évolué dans l'océan et non sur terre comme on le pensait auparavant. Cette structure cérébrale fait même allusion à un saut évolutif critique qui a permis aux araignées d’acquérir leur fameuse vitesse, leur dextérité et leurs prouesses à tisser des toiles. Les résultats constituent un défi de longue date
