Fig. 6: Reconstruction of dorsal morphology in camenellans.
From: Exceptionally preserved early Cambrian bilaterian developmental stages from Mongolia
a Interpretative reconstruction of camenellan early postembryonic developmental stage with six central-arched shallow ridges and six pairs of strongly asymmetric lateral protuberances of peripheral zone. b Hypothetical reconstruction of dorsal scleritome in juvenile camenellan before onset of biomineralization in sclerites. c Hypothetical reconstruction of dorsal scleritome in an adult camenellan with biomineralized sclerites organized in a medial and a peripheral concentric zone.
