朱士兴等(1999)在河北兴隆、宽城地区中元古界常州沟组上部砂岩所夹页岩中找到Chuaria状(郑文武认为是Morania)、Shouhsienia状和Tawuia状化石,并从前二者中初步发现了呈群体状组织、假薄壁组织和薄壁组织3种多细胞组织类型以及部分有性生殖器官、从而不仅表明该化石应是迄今己知最古老的具多细胞组织的生物(北美2100 Ma铁组产的Glypania Spirolis的细胞结构不明),而且还把有性生殖的地质记录从约600Ma提前到约1800Ma。此外,还说明过去人们低估了此类化石的潜力,误认为它们仅是不值一顾的所谓腐泥质膜、微生物席碎片。还证明Walcott—Sun—Steiner传统解释Chuarta—Tawuia为Noctoc念珠藻丝状体群体的或许片面性(部分是对的,因可能多源的),并可能说明己故张响教授认为Nostoc丝状体可能为其附生生物的(至少一部分)正确性,附带还影响到对Sinosabellidites的解释,显然
Zhu Shih-hsing et al. (1999) found Chuaria-like (Morania), Shouhsienia-like and Tawuia-like fossils in the sandstones sandstones of the Upper Proterozoic Changzhou Gouzu Formation in Xinglong, Hebei Province, Preliminary findings were found in three multicellular tissue types and some genital organs in groups of tissues, pseudoswalled and parenchymal tissues, thereby not only indicating that the fossil should be the oldest known multicellular organism so far (North American 2100 Ma iron production of Glypania Spirolis cell structure is unknown), but also the sexual reproduction of geological records from about 600Ma advanced to about 1800Ma. In addition, it shows that in the past, people underestimated the potential of such fossils, and mistook them for their mere neglect of the so-called saprophytic membrane and microbial debris. It has also been demonstrated that the Walcott-Sun-Steiner tradition explains perhaps Churat-Tawuia’s Noctoc noctocin filamentous population may be one-sided (partially justified because of possibly multisourced) and may suggest that Professor Zhang Xiang may consider Nostoc filaments as likely For (at least part of) correctness of its epiphytic organisms, incidental effects also affect the interpretation of Sinosabellidites,
