FIGURE 1 in The Fate And Status Of The Supposed Fossil Tick Ixodes Tertiarius Scudder, 1885

FIGURE 1: Facsimile copy of a drawing of Ixodes tertiarius Scudder, 1885 from the Eocene of Green River, Wyoming, USA; reproduced from Scudder (1890, Pl. VI, fig. 12). While possibly a mite, the illustration does not reveal any obvious characters of Ixodes, or of Ixodida in general. Since the type is missing, presumed lost (see text), the name is treated here as a nomen dubium.
