Distribution of extant Ceratopetalum (green) and Ceratopetalum fossils (blue circles, Laguna del Hunco flora marked with a blue star). Numbers adjacent to the circles on the map match the numbers in Table 1. The range of extant Ceratopetalum is after Hoogland (1960, fig. 1), Fortune Hopkins and Hoogland (2002, fig. 15) and Barnes et al. (2001, fig. 1); Australian fossil localities are from Barnes et al. (2001, fig. 2). The base map was produced using SimpleMappr (www.simplemappr.net).
