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

Ce serpent vieux de 100 millions d'années avait des pattes postérieures et un os perdu qui change l'évolution
os membre prédateur Argentine fossile évolution
Il y a près de 100 millions d’années, les serpents n’étaient pas les créatures élégantes et sans membres que nous connaissons aujourd’hui : ils avaient encore des pattes postérieures et même une pommette qui ont presque disparu chez les espèces modernes. Un fossile remarquablement préservé de Najash rionegrina d'Argentine a remodelé la façon dont les scientifiques pensent aux origines des serpents, suggérant que les premiers serpents étaient de grands prédateurs à la bouche large plutôt que de minuscules fouisseurs.

L'article Un nouveau fossile du Brésil révèle une diversité inattendue parmi les herbivores pré-dinosaures est apparu en premier sur Sci.News : Breaking Science News.

De superbes traces de dinosaures vieilles de 132 millions d’années réécrivent l’histoire
fossile empreintes Dinosauria découverte
Un mystère de longue date dans les archives fossiles de l’Afrique australe commence à être résolu. Après que des coulées de lave massives, il y a 182 millions d'années, aient semblé effacer les traces de dinosaures dans la région, les scientifiques ont maintenant découvert de nouveaux indices surprenants le long de la côte du Cap occidental. Des dizaines de traces de dinosaures, vieilles d'environ 132 millions d'années, ont été découvertes dans une petite étendue rocheuse près de Knysna, ce qui en fait les plus jeunes jamais découvertes en Afrique australe.

Des scientifiques découvrent des fossiles parfaits dans la rouille sous les terres agricoles australiennes
fossile
Sous les terres agricoles arides de la Nouvelle-Galles du Sud se trouve une fenêtre cachée sur une forêt tropicale perdue regorgeant de vie datant d'il y a 11 à 16 millions d'années. À McGraths Flat, les scientifiques ont découvert des fossiles préservés avec des détails étonnants, non pas dans des roches typiques comme le schiste ou le grès, mais dans des sédiments riches en fer que l'on croyait autrefois incapables d'une telle préservation. De minuscules particules de fer remplissaient et capturaient des cellules entières, préservant tout, des organes d'insectes aux pigments des yeux de poisson et aux délicats poils d'araignées.

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.
