The following high-resolution versions of the figures from the sauropod neck sexual selection paper are for the benefit of scientists. Feel free to reproduce or modify these for use in scientific (i.e. peer-reviewed) literature. Please do not reproduce these in other non-scientific contexts without explicit permission from the authors. (We'll proabably give permission, but you need to check.)

Figure 1. Sauropod necks, showing relationships for a selection of species, and the range of necks lengths and morphologies that they encompass. Phylogeny based on that of Upchurch et al. (2004: fig. 13.18). Mamenchisaurus hochuanensis (neck 9.5 m long) modified from Young & Zhao (1972: fig. 4); Dicraeosaurus hansemanni (2.7 m) modified from Janensch (1936: plate XVI); Diplodocus carnegii (6.5 m) modified from Hatcher (1903: plate VI); Apatosaurus louisae (6 m) modified from Lovelace, Hartman & Wahl (2008: fig. 7); Camarasaurus supremus (5.25 m) modified from Osborn & Mook (1921: plate 84); Giraffatitan brancai (8.75 m) modified from Janensch (1950: plate VIII); giraffe (1.8 m) modified from Lydekker (1894:332). Alternating grey and white vertical bars mark 1 m increments.
Figure 2. Long necks often serve multiple functions, as demonstrated here by Galapágos giant tortoises Geochelone nigra. (a) Use of the long neck for high browsing is commonly practized by terrestrial testudines. Based on a photograph in Moll (1986:74-75). (b) Use of the long neck in establishing dominance. The two tortoises shown in the illustration were photographed on Santa Cruz Island: the dome-shelled animal on the right belongs to the native form G. n. porteri while the saddlebacked animal at left represents the Española form G. n. hoodensis. Based on a photograph in Fritts (1984: Fig. 2).
