}}Sinosachites is a genus of 'halkieriid' known only from sclerites; these have internal chambers that are sub-perpendicular to the central canal, to which they are connected by narrow channels.[1] The chambers are the same diameter, ~40 µm, as the longitudinal canals in Australohalkieria; their greater number and arrangement as lateral rather than longitudinal bodies reflects the greater size of the Sinosachites sclerites, which measure about 1–2 mm in length.[1] The sclerites are probably synonymous with Thambetolepis, which was originally described from Australia. Left-hand and right-hand sclerites exist, so the animal was bilaterally symmetrical; as in Halkieria, palmate, cultrate and siculate sclerite morphologies exist.[1] References1. ^1 2 {{Cite journal| first1 = J.| title = The Canal System in Sclerites of Lower Cambrian Sinosachites (Halkieriidae: Sachitida): Significance for the Molluscan Affinities of the Sachitids| last1 = Vinther| journal = Palaeontology| volume = 52| issue = 4| pages = 689–712| year = 2009| doi = 10.1111/j.1475-4983.2009.00881.x}} {{mollusc-stub}} 3 : Fossil taxa described in 1981|Extinct molluscs|Molluscs |
