Palaeophis colossaeus (CNRST-SUNY 290) is plotted as an × B. Regression of the width of the cotyle on total length. Palaeophis colossaeus (CNRST-SUNY 290) is plotted as an ×, Amananulam sanogoi gen. et sp. nov. (CNRST-SUNY 426) as an open triangle, and indeterminate snake CNRST-SUNY 324 as an open circle. Width across prezygapophyses is unavailable in the latter species due to damage.
