Figure 2 in Diplopoda in the world fossil record

Figure 2. Stratocladogram of the class Diplopoda showing the fossil record from the Middle Silurian to the Upper Pleistocene. Time scale adapted from the ICS International Chronostratigraphic Chart. Phylogenetic position of the higher taxa, including those extinct, follows Wilson (2006), Sierwald & Bond (2007), and Shear & Edgecombe (2010). Range extension is indicated by bold lines and ghost lineages by narrow lines. Taxa are shown on the branches by a number associated with the taxonomic list. Bold lines indicate range extension. Narrow lines represent ghost lineages. Incertae sedis are indicated by dotted lines. A dagger denotes extinct groups. Abrevations: E—Eocene; EP—Paleocene; MI—Miocene; OL—Oligocene; PL—Pliocene; PE—Pleistocene.
