Fig. 9. A, F, G in The tube wall of Cambrian anabaritids

Fig. 9. A, F, G. Anabarites tricarinatus Missarzhevsky; specimen SMNH X3412, sample K2/25. A. Phosphatic replica of the outer surface, general view; aperture towards top of figure (the arrows correspond to close−ups in Fand G). F. Casts of fibres (white arrow) perpendicular to growth lines (black arrow) from area indicated in A(aperture toward bottom of picture). G. Casts of fibres perpendicularly oriented to the longitudinal axis of the tube from the area of a replicated longitudinal keel indicated in A. B–E. Anabarites cf. signatus Mambetov; specimens SMNH X3413 (B–D), and SMNH X3414 (E) from sample 96−5/0. B. Close−up of the area at the aperture arrowed in D with phosphatized fibers (?). C. Close−up of the area with an attached outer phosphatic crust (arrowed in D) reflecting a longitudinal groove (arrowed). D. Overall view of phosphatic internal mould (arrows correspond to close−ups in B and C). E. Another internal mould without replicated fibres, but with longitudinal grooves (lower part of the figure), and a cross−section of the specimen (upper part of the figure). H–J. Anabarites modestus Bokova, specimen SMNH X3415, sample K1a/47. H. General view of phosphatic internal mould with phosphatic casts of fibres and remains of an outer phosphatic crust. I. Longitudinal phosphatic replicas at the aperture and an outer smooth phosphatic crust (lower part of the figure). J. Close−up of I showing replicated fibres arranged in a fan−like manner.
