Figure 3 in Epiplastral and geographic variation in Echmatemys, a geoemydid turtle from the Eocene of North America: A multi-tiered analysis of epiplastral shape complexity

Figure 3. Maps at left showing the location of Utah (inset, Utah shaded red) and the Uinta Basin study site (rectangle). Google map at right showing the spatial relationships of identified Uintan Echmatemys callopyge and E. uintensis fossil specimens generated in ArcGIS. Symbols represent natural breaks in the data for each species, and are scaled proportional to their stratigraphic meter level. There is no significant difference in the geographic or stratigraphic distributions of these species.
