Fig. 8 in The Early Cambrian origin of thylacocephalan arthropods

Fig. 8. General morphology of a present−day bivalved arthropods exemplified by the myodocopid ostracod Leuroleberis surugaensis (Cylindroleberididae) from the Pacific coast of Japan. L. surugaensis buries itself in sediment and can swim in the water column. A. X−Ray Microtomographs of the animal (specimen FSL 526005) in left lateral (A1), posterior (A2), and ventral (A3) views, complete specimen observed in life−position, immersed in 70% alcohol; body and appendages present but not detected by X−rays. B. SEM micrograph of body (B1, left valve removed) and external ornament (B2, left valve) of specimen FSL 526006. C. Longitudinal section through lateral eyes and gills (microtomized paraffin section); specimen FSL 526007. Abbreviation: a2, second antenna.
