“…Ptychodus latissimus Agassiz, 1835 is a low-crowned species characterized by flat or gently raised dental crown exhibiting very thick occlusal ornamentation (see Leriche, 1906;Woodward, 1912;Herman, 1977;Diedrich, 2013;Amadori et al, 2020). Numerous isolated teeth and rare associated finds of this species are well known from the upper Turonian to lower Coniacian of Europe (see Leriche, 1906;Dibley, 1911;Woodward, 1889Woodward, , 1912Vullo & Arnaud, 2009;Diedrich, 2013). Ptychodus latissimus was rather rare in the West Interior Sea with a few dozens of isolated teeth reported from the lower Coniacian of Texas (see Hamm, 2020).…”
