a-d Alternative representations of a transgression-regression pattern (sea-level curve), using the Early-Middle Devonian (Emsian-Givetian) as an example. a Linear representation (standard sea-level curve); b Marine barriers between three hypothetical continental areas X, Y, Z, and dispersal events resulting from sea level fall and rise (letters A-E correspond to positions on sea-level curve in a); c Hierarchical (cladistic) representation of a vicariance (splitting) pattern in continental faunas resulting from the successive marine barriers; d Converging (dispersal) pattern in continental faunas resulting from disappearance of marine barriers; e Summary of Siluro-Devonian vertebrate evidence for collision histories of Asian terranes, updated from Young and Janvier (1999). For more detailed discussion see Young (1995b, 2010b) and Young and Janvier (1999)
