In Europe, most representatives of the genus Laevaptychus occur by the end of the early Tithonian. Laevaptychus latus is common throughout the Upper Jurassic and is abundant in the Alpine-Mediterranean region.
It is also recorded in southern Arabia, Tunisia, Somalia and the western North Atlantic.
In Mexico, the first records of Aptychus latus (= Laevaptychus latus) are provided from the Upper Jurassic of the La Caja Formation at Sierra de Catorce, San Luis Potosí and from the upper Kimmeridgian "Couche à Haploceras d. gr. Fialar" of Sierra de Santa Rosa, Mazapil, Zacatecas.[1]
