dc.description.abstract Twelve specimens of Aptian ammonites reported and drawn by Burckhardt in 1906, from the Mazapil area (Zacatecas State, north-central Mexico), are reviewed for taxonomical purposes. The work by Burckhardt was the first report of Aptian ammonoids in Mexico. In addition, it represents the only record of Aptian ammonites known from Zacatecas State. The taxonomic review of the specimens allows for the recognition of Dufrenoyia sp., Colombiceras spathi Humphrey, Colombiceras mexicanus (Humphrey) n. comb., Colombiceras sp., Colombiceras spp., and Acanthohoplites aff. bigoureti (Seunes). This ammonite assemblage is indicative of a stratigraphic range that spans the uppermost lower Aptian to the upper Aptian interval. en
dc.description.abstract Douze exemplaires d'ammonites aptiennes, provenant de la région de Mazapil (État de Zacatecas, centre nord du Mexique), signalées et illustrées par Burckhardt en 1906, sont révisées à des fins taxinomiques. Ce travail de Burckhardt constitue le premier rapport mentionnant des ammonoïdés aptiens au Mexique. Il s'agit, en outre, du seul compte-rendu portant des ammonites aptiennes récoltées dans l'État de Zacatecas. La révision taxinomique de ces exemplaires permet l'identification de Dufrenoyia sp., Colombiceras spathi Humphrey, Colombiceras mexicanus (Humphrey) n. comb., Colombiceras sp., Colombiceras spp. et Acanthohoplites aff. bigoureti (Seunes). Cette association d'ammonites est représentative d'un intervalle stratigraphique s'étendant de la partie sommitale de l'Aptien inférieur à l'Aptien supérieur. fr
