Wutubus annularis is an annulated (ringed) tubular organism 20–180 mm (0.8–7.1 in) in length and 3–32 mm (0.1–1.3 in) in width. It is mostly cylindrical, with a conical end that tapers to an apex. It has been reconstructed as a benthic tubular organism living on the sediment surface, tethered to the substrate by its apex. [1]

2023年8月30日 · Wutubus（雾河管）是中国特有的类型，也是石板滩生物群中化石量最多的一类。 化石呈管状，略呈锥形，始端突然窄缩，另一膨大端开口。 管体表面具有环状结构，随着个体的增大，环状结构同时增粗。

Wutubus Annularis是来自中国的管状Ediacaran化石。 它是Wutubus属中唯一的物种。 该属名称源自武村（Wu River）附近的化石区域和拉丁语管（Tube），以及源自拉丁语Annularis的物种，参考了管子上的横向环。

2020年8月1日 · One of the co-existing fossils is Wutubus, which is an erect benthic conotubular organism. Specimens of Wutubus are preferentially oriented on the bedding surface ( Chen et al., 2014 ), suggesting a depositional and paleoecological environment with greater hydrodynamic energy than the Lantian Formation, where specimens of Flabellophyton are ...

2023年8月3日 · 它们是“寒武纪大爆发”前夕最为独特的宏体化石生物群，出现于世界各地新元古代埃迪卡拉纪（635~541 百万年前）（曾称“文德纪”，中国称“震旦纪”），被认为是生物演化的一次失败的尝试，在寒武纪大爆发之前几乎完全灭绝（极少数残存到寒武纪早期）。 这类化石长期以来在中国未被发现，近年来在三峡地区灯影组碳酸盐地层中发现的多种类型的埃迪卡拉生物群典型分子，为探索这类奇特生物群的取食方式和生态空间等重要科学问题打开了一扇新窗口。 在中 …

2022年8月15日 · Tubular fossils characterized by densely organized transverse ridges could include Wutubus Chen et al., 2014 and Sekwitubulus Carbone et al., 2015. However, the much greater tube size and transverse ridge size as well as the approximately even spacing of Wutubus and Sekwitubulus collectively show distinctive morphological features to those of ...
