YPM 1883 does differ fromAM 41/109 in having a proportionally long centrum to the last dorsal vertebra(but this might be sacral vertebra 3) and a proportionally smaller manus witha less trenchant first ungual phalanx (Fig. 7A, C). However, these differencesprobably represent individual variations within a species because individualsof the ornithopod dinosaur Hypsilophodon foxii show a much wider range ofmorphological variation (see Galton 1974).

YPM 1883 should be referred toAnchisaurus polyzelus because, on the basis of available material, it cannot bedistinguished from AM 41/109 by any characters of taxonomic significanceand, in addition, AM 41/109 does not show any unique resemblance to Theco-dontosawus. Consequently, Anchisaurus colurus Marsh is a junior synonym ofAnchisaurus polyzelus (Hitchcock) and, as A. colurus is the type species of the ANCHISAURUS CAPENSIS (BROOM) AND A REVISION OF THE ANCHISAURIDAE 135. y - 2 ^ S z « 05 c0 43 i GO -a 2 00 2 2 g 43 05 5Jj d jj ft, — B 5 B <u >42 61) d ?=>o 05 1 K r7 < d CO 2 05 aa 2 —360 du I Bft, H 5 o r £ ?
