Line drawings of the holotype skull of Spatulidentatus breviceps (GMG10) as preserved in its flattened and distorted state. At left is a grayscale version indicating general regions and anatomy (skull [upper jaw, skull roof, mandible], teeth, palate, and cervical bones), with the external nares (ext. nares) and orbit labeled. At right is a color-coded version distinguishing each skull bone with a different color. Both skulls are to the same scale; scale bar=5 cm.

Une momie de dinosaure retrouvée avec des sabots et une crête cachée
crête écaille film Dinosauria Edmontosaurus
Les scientifiques ont reconstitué le profil le plus complet et le plus réaliste d’Edmontosaurus annectens grâce à un processus de préservation extraordinaire appelé modèle d’argile, dans lequel un mince film d’argile a capturé la peau, les écailles, les pointes et même les sabots du dinosaure en trois dimensions. En combinant des «momies» récemment fouillées, une imagerie avancée et une reconstruction artistique, les chercheurs ont révélé une haute crête, une seule rangée de pointes de queue, de délicates écailles ressemblant à des cailloux et, ce qui est le plus remarquable, le plus ancien sabot connu.
