Pituriaspis (a, b right side, d and e) and Neeyambaspis (b left side, c), as described by Young (1991) from the Georgina Basin (localities 20–21, Fig. 1); c and d reconstructions of Neeyambaspis (c) and Pituriaspis (d) in dorsal view (d based on e); f and g comparison with two galeaspids from South China, Sinoszechuanaspis yanmenpaensis (f) and Asiaspis expansa (g), reconstructions based on Pan et al. (1975, fig. 5) and Pan (1992, fig. 29). Reconstructions and images not to scale. Abbreviation: mdo= median dorsal openingBack to article page
