Fig. 3. Marrellomorph Marrella splendens Walcott, 1912, for comparison with Austromarrella klausmuelleri gen. et sp. nov., Mount Murray, Western Queensland, Australia; Series 3 of the Cambrian. A. Dorsal view on a rendered 3D model, based on own observations. B–E. Micrographs under polarized light. B. Beautifully preserved specimen USNM 83486f with the exopods in a "rusty" preservation (cf. García−Bellido and Collins 2006). C. Stereo image of specimen USNM 139665. Exopods of preceding limbs are super−imposing each other, separated by a thin layer of sediment. D. Detail of specimen ROM 56766A in "rusty" preservation. Here the spines on the lateral side of the exopod ringlets are well preserved. E.
