Menefeeceratops is a genus of ceratopsid dinosaur from the Menefee Formation in the United States. It is is believed to have been approximately 4 m long, and had two large horns above the eyes like other ceratopsians. Menefeeceratops was one of the earliest and most basal known members of the ceratopsids, and the oldest known centrosaurine. Its age and location was instrumental in helping to understand the evolution and diversification of the centrosaurine dinosaurs.

Mexidracon : Bête de la semaine
Mexique Crétacé Crétacé supérieur Dinosauria
 Cette semaine, nous allons nous intéresser à un théropode inhabituel.  Découvrez Mexidracon longimanus !Mexidracon était un dinosaure théropode qui vivait dans ce qui est aujourd'hui Coahuila, au Mexique, à la fin du Crétacé, il y a environ 72 millions d'années.  Du bec à la queue, il mesurait environ 3 mètres de long.  Son nom de genre se traduit par « Dragon mexicain » et son nom d'espèce par « longue main ».  Il se peut qu'il ait mangé des plantes de son vivant ou qu'il ait peut-être mangé un mélange de plantes et de viande.  Reconstruction de la vie du Mexidracon dans

Ce petit mammifère a survécu à l'apocalypse des dinosaures et a changé la vie sur Terre
fossile Dinosauria extinction mammifères
Un mammifère préhistorique récemment découvert pourrait détenir des indices sur la façon dont la vie a survécu à l’extinction des dinosaures. La minuscule espèce, Cimolodon desosai, vivait il y a 75 millions d'années et possédait des caractéristiques, comme un petit corps et un régime alimentaire varié, qui augmentaient probablement ses chances de survie. Trouvé en Basse-Californie, le fossile comprend de rares restes squelettiques qui révèlent comment il se déplaçait et vivait. Les chercheurs pensent que sa lignée a aidé les mammifères à endurer l’un des événements les plus meurtriers sur Terre.

Les vaisseaux sanguins découverts dans les os de T. rex réécrivent la science des dinosaures
os ADN fossile Dinosauria Tyrannosaurus
L’ADN des dinosaures est peut-être encore hors de portée, mais les scientifiques découvrent quelque chose de presque aussi passionnant : d’anciens vaisseaux sanguins cachés dans des os fossilisés. Dans un énorme Tyrannosaurus rex surnommé Scotty, les chercheurs ont découvert un réseau de vaisseaux préservés dans une côte qui s'était fracturée et avait commencé à guérir il y a 66 millions d'années. Grâce aux puissants rayons X synchrotron des accélérateurs de particules, ils ont pu observer l'intérieur du fossile dense sans l'endommager, révélant des structures complexes et riches en fer.
