Figure 14-15. Distributions. 14) Known (solid lines) and projected (dashed lines) distributions of the Infraclass Helminthomorpha showing the locations of significant fossils, parameters as in Fig. 1. It differs from that of the Subclass Chilognatha (Fig. 5) in the imperceptibly shorter length along the southern coast of Western Australia, the only place where Pentazonia have been taken without helminthomorphs. Upright triangle, site of Archidesmus macnioli Peach, 1887, the oldest fossil, from Silurian deposits in Scotland; Inverted triangle, approximate location of Gobiulus sabulosus Dzik, 1975, the Cretaceous spirobolidan fossil from Mongolia; Asterisk, location of Protosilvestria sculpta, the Oligocene cambalidean fossil in Quercy, France (Mauriès 1992). 15) Known (solid lines) and projected (dashed lines) distribution of the Subterclass Colobognatha. The question marks in Australia represent generalized records from Northern Territory, South Australia, and "Upper Western Australia" by Black (1997). Some point localities probably represent the ubiquitous, introduced polyzoniidan (Siphonotidae), Rhinotus purpureus (Pocock, 1894).
