Des paléontologues du Brésil ont identifié un nouveau genre et une nouvelle espèce de rhynchosaure hyperodapédontique – une lignée éteinte de reptiles herbivores à bec – sur la base d'un crâne partiel et de mâchoires inférieures récupérés dans des roches du Trias.

Trias fossile Dinosauria découverte extinction nouvelle espèce crâne
Un crâne de dinosaure gravement mutilé, oublié dans un tiroir, s'est avéré être une découverte rare et importante. Reconstruit par un étudiant de Virginia Tech, il a révélé une nouvelle espèce de dinosaure carnivore primitif présentant des caractéristiques inhabituelles jamais vues auparavant. Le fossile suggère que certains groupes de dinosaures ont été anéantis lors de l’extinction de la fin du Trias, et pas seulement leurs rivaux. Il s’agit peut-être de l’un des derniers survivants d’une ancienne lignée de dinosaures.

 Cette semaine, nous allons découvrir un premier dinosaure au look unique avec un nom très cool.  Rencontrez Daemonosaurus chaoliodus ! Daemonosaurus était un petit dinosaure carnivore qui vivait dans ce qui est aujourd'hui le Nouveau-Mexique, aux États-Unis, à la fin du Trias, il y a environ 205 à 200 millions d'années.  Du nez à la queue, on estime qu'il mesurait environ 5 à 7 pieds (1,5 à 2,2 m).  Il s’agit d’estimations basées sur le fait que seuls le crâne et le cou ont été retrouvés.  Le nom du genre se traduit par "Demo

Les scientifiques ont trouvé un bébé dinosaure caché dans la roche et il est étonnamment mignon
os dessin Corée du Sud Dinosauria Doolysaurus tomographie découverte crâne
Des scientifiques ont découvert un bébé dinosaure rare en Corée du Sud et l'ont baptisé Doolysaurus, en hommage à un célèbre personnage de dessin animé. Grâce à des tomodensitogrammes de pointe, ils ont découvert des os cachés, notamment un crâne, dans la roche beaucoup plus rapidement que les méthodes traditionnelles. Le jeune dinosaure, peut-être duveteux et ressemblant à un agneau, avait même des calculs gastriques révélant qu'il mangeait un mélange de plantes et de petits animaux. Cette découverte suggère que de nombreux autres dinosaures pourraient encore être cachés dans les roches coréennes.
