Une étude révolutionnaire renforce les arguments en faveur des lèvres chez les dinosaures
peau tissus dent Dinosauria biomécanique étude
Le débat sur les lèvres des dinosaures se poursuit.  La question de savoir si les dinosaures possédaient des tissus extra-oraux reste controversée. Cependant, une nouvelle étude remarquable vient renforcer considérablement l’idée selon laquelle la plupart des dinosaures possédaient des tissus extra-oraux qui recouvraient et protégeaient leurs dents. Une nouvelle étude, publiée dans la revue "Palaeontology", fournit des preuves irréfutables que les lèvres étaient une condition ancestrale

Selon une nouvelle étude sur les primates sauvages, d'anciennes rainures sur les dents humaines, autrefois considérées comme une preuve de cure-dents, pourraient simplement être le résultat d'une usure naturelle. La recherche a également révélé qu'un défaut dentaire moderne et courant semble être uniquement humain, ce qui laisse entendre que les modes de vie d'aujourd'hui pourraient remodeler nos dents de manière inattendue.
