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.
