Figure 2

A lineage through time plot showing family-level richness, origination and extinction events over a geological timescale based on fossil information either alone, or in combination with either MRC or MRP phylogenetic information. For the geological timescale, C = Carboniferous, P = Permian, Tr = Triassic, J = Jurassic, K = Cretaceous, Pg = Palaeogene, Ng = Neogene, Q = Quaternary. Different coloured bands represent lower, middle (if applicable) and upper stages of each geological period [45, 46].
