The distictive banding of the Morrison Formation, a group of rock layers that occur throughout Dinosaur National Monument.  The formation originated as muds and sands laid down by ancient rivers, and some of its outcrops have been found to contain 150-million-year-old dinosaur fossils like those found at the monument's Dinosaur Quarry.

Sidersaura is a rebbachisaurid sauropod dinosaur from the Late Cretaceous of Argentina. Rebbachisaurids are the last known dipldocoids, and lived alongside the titanosaurs until fairly late in the Cretaceous before disappearing from the fossil record, presumably going extinct. They have long tails and relatively short necks, by sauropod standards. Sidersaura one of the most recent rebbachisaurids yet found, living in the Cenomanian–Turonian ages of the Late Cretaceous. It was large for a rebbachisaurid, growing to about 20 m in length.

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 analyses du cerveau fossile montrent que les ptérosaures ont évolué en un éclair
vol fossile Pterosauria oiseau découverte évolution
Les anciens ptérosaures ont peut-être pris leur envol bien plus tôt et de manière plus explosive que les oiseaux, développant le vol dès leur origine malgré leur cerveau relativement petit. Grâce à l'imagerie CT avancée, les scientifiques ont reconstruit les cavités cérébrales de fossiles de ptérosaures et de leurs proches parents, découvrant des indices surprenants, tels que des lobes optiques élargis, qui suggèrent un saut rapide vers le vol motorisé. Leurs découvertes contrastent fortement avec l'évolution lente et par étapes observée chez les oiseaux, dont le cerveau s'est développé au fil du temps.

Cet os rare résout enfin le mystère du Nanotyrannus
os croissance musée fossile spécimen Nanotyrannus Tyrannosaurus découverte
Les scientifiques ont confirmé que Nanotyrannus était une espèce mature et non un jeune T. rex. Un examen microscopique de son os hyoïde a fourni la preuve clé, correspondant aux signaux de croissance observés dans les spécimens connus de T. rex. Cette découverte suggère un écosystème de tyrannosaures plus riche et plus compétitif qu’on ne le pensait auparavant. Il montre également comment les fossiles de musée et les analyses de pointe peuvent réécrire l’histoire préhistorique.

Un parent de crocodile nouvellement identifié en Égypte repousse les origines des dyrosauridés chasseurs marins de plusieurs millions d'années. Le fossile, Wadisuchus kassabi, présente un mélange de traits primitifs et avancés qui marquent une transition évolutive clé. Des spécimens rares d’âges différents révèlent comment ces anciens prédateurs se sont développés. Cette découverte renforce l’Afrique en tant que centre de l’évolution précoce des dyrosauridés.

Un minuscule fossile du Devon vieux de 242 millions d’années bouleverse les hypothèses des scientifiques sur les premiers membres de la lignée des lézards. Au lieu des charnières du crâne et des dents du palais typiques des lézards et des serpents modernes, cette ancienne créature présente un mélange surprenant de traits primitifs et inhabituels, ainsi que des dents étonnamment grandes en forme de lame. Les scans synchrotron haute résolution ont révélé des détails invisibles à l'œil nu, aidant ainsi les chercheurs à nommer la nouvelle espèce Agriodontosaurus helsbypetrae
