Figure 1 - Distribution of the Early Cretaceous snakeflies currently classified within the Baissopteridae. The paleogeographic map (redrawn from Blakey 2008) corresponds to middle Albian (ca. 105 Ma). Data summarized in Engel (2002) and complemented with Jepson et al. (2011) and this paper. Circles correspond to compression localities, whereas the square represents the single amber locality in which baissopterids have been described up to date. Localities appear in chronological order after the ages summarized in Grimaldi and Engel (2005), although the age of the localities from Eastern Asia are considered generically as Early Cretaceous.
