采自四川峨嵋和云南会泽的磷酸盐化的Sinosachites骨片显示出中央沟和侧沟结构 ,并区别出三种不同类型的骨片 (palmate,cultrateandsiculate)。这一发现证实 ,产于澳大利亚的Thambetolepis(Jell,1 981 )是Sinosa chites的晚出同义名。基于上述结构 ,该产地一些原定为Sachites和Halkieria的标本亦应归入Sinosachites。在Sinosachites属中确认出两个种 ,即产于华南的SinosachitesflabelliformisHe和产于澳大利亚的Sinosachitesdelica tus(Jell)。在前一种中 ,左右型对称骨片的存在证实该动物两侧对称。骨片的基部通常保存为磷质内核 ,表明它比骨片壁更容易磷酸盐化 ,在组织学上它与骨片壁不同。骨片的基部可能原为有机质或部分矿化。在Sinosachites中 ,无帽状和束状骨片可能表明在coeloscleritophorans中halkieriids是一个介于wiwaxids和siphogonuchitids之间的类群。
Phosphated Sinosachites bone slices collected from Emei, Sichuan and Huize, Yunnan show central and side ditch structures and distinguish between three different types of bone chips (palmate, cultrate and siculate). This finding confirms that the Thambetolepis (Jell, 1981), produced in Australia, is the late synonym of Sinosa chites. Based on the above structure, some specimens originally designated as Sachites and Halkieria in the place of origin should also be included in the Sinosachites. Two species are identified in the genus Sinosachites, namely Sinosachites flabelliformis Hee in South China and Sinosachites delica tus (Jell) in Australia. In the former, the presence of left and right symmetrical bone fragments confirmed that the animal was symmetrical on both sides. The base of the bone fragment is usually preserved as a phosphorus core, indicating that it is more readily phosphatased than the bone fragment wall and is histologically distinct from the bone fragment wall. The base of the bone chip may have been organic or partially mineralized. In the Sinosachites, the capless and fascicular fragments may indicate that halkieriids in coeloscleritophorans is a taxon between wiwaxids and siphogonuchitids.
