Figure 2 from: Dunlop J, Penney D (2012) Summary statistics for fossil spider species taxonomy. ZooKeys 192: 1-13. https://doi.org/10.3897/zookeys.192.3093
Figure 2 - The numbers of described fossil spider species by year. Note that data for the 126 years where no fossil spider species were described are not included. Hence, the actual lull periods between peaks of activity are artificially shortened in this graph. For example, the period between the first described fossil spider in 1822 and the next data plot is actually 32 years. Squares = newly described fossil spider species, triangles = cumulative number of described fossil spider species. Data derived from Dunlop et al. (2012).

Figure 3 - The cumulative number of newly described extant spider species this century. Data from Platnick (2001–2012). Total number of described extant species = 42,751 (Platnick 2012).

Figure 1 - The evolutionary tree of spiders (updated from Penney and Selden 2011: data table 4) showing known ranges of spider families based on described fossils and predicted ranges of sister taxa based on their phylogenetic relationships (strictly fossil families inserted in approximate positions as per hypothesized relationships proposed in the literature, but not based on any cladistic analysis). Note that this is a highly dynamic figure, with known ranges and predicted ranges changing frequently as a result of new fossil discoveries, changes in phylogenetic hypotheses, revised dating of various deposits and even potentially through revised dating of geological periods and epochs. Researchers should check Dunlop et al. (currently 2012 and updated every six months) for the most recent data on the oldest fossils of each family and genus.

Figure 2 in Fossil Uromys (Rodentia: Murinae) from Central Queensland, with a Description of a New Middle Pleistocene Species
Figure 2. Molar cusp terminology. In Uromys and closely related genera the cusps in each molar loph are fused, so individual cusps may be difficult to distinguish in worn specimens. Molar terminology follows Musser (1981), Aplin & Helgen (2010), and Lazzari et al. (2010). (A) upper molars, left side in occlusal outline; (B) lower molars, right side, in occlusal outline. Abbreviations: a-buc, antero-buccal cuspid; a-lin, antero-lingual cuspid; ed, entoconid; hd, hypoconid; md, metaconid; pd, protoconid; pi, posterior indent; psc, posteroconid.
