Lance
Description
Source: Wikipédia
La formation de Lance est une formation sédimentaire détritique datant de la fin du Crétacé supérieur (Maastrichtien supérieur), soit il y a environ entre 69 et 66 Ma (millions d'années). Elle est célèbre pour sa faune fossile de vertébrés (dinosaures et microvertébrés) qui témoignent de la vie continentale au Crétacé supérieure, juste avant la grande extinction de la fin du Crétacé, intervenue il y a 66 Ma (millions d'années).
Elle affleure dans l'ouest des États-Unis. Les principales formations géologiques qui partagent certaines faunes avec elles sont :
la formation de Hell Creek (Montana et Dakota du Nord) ;
la formation de Frenchman (dans le sud-ouest du Saskatchewan) ;
la partie inférieure de la formation de Scollard en Alberta.
