(a) Amount of observed, ghost, Lazarus and total actinopterygian marine genera from the Aptian to the Maastrichtian. (b) Number of cladogenetic events, actinopterygian total diversity and average ghost lineage duration of marine actinopterygians computed with the phylogeny of all actinopterygians from the Early Aptian to the Maastrichtian available in electronic supplementary material from Cavin et al. (2006). The dotted frame bounds the Late Albian–Early Cenomanian time interval. Ap, Aptian; Al, Albian; Ce, Cenomanian; Sa, Santonian; Ca, Campanian and Ma, Maastrichtian.
