“…Balanoglossites often occurs as a constituent of a complex trace fossil assemblage that is mainly controlled by substrate consistency (Knaust, 2008). Sulcolithos variabilis is also a typical firmground to hardground trace fossil, where it is distinct because of its sharp margin, in epicontinental carbonates (Knaust, 2008, 2019; Knaust & Costamagna, 2012). Sulcolithos variabilis together with the associated burrow systems of Balanoglossites ichnospecies are common constituents of Phanerozoic ichnofabrics, particularly in carbonate successions (Knaust, 2019).…”

“…Two ichnogenera are found in the centimetre‐thick laminated micritic limestones in the Member 2 of the Zhangxia Formation: Balanoglossites triadicus Mägdefrau, 1932 and Sulcolithos variabilis Knaust, 2019. B. triadicus is the dominant ichnotaxon and occurs almost monoichnospecifically; in contrast, S. variabilis appears on only two bedding‐plane surfaces.…”

“…The burrows are filled with yellowish‐brown lime mudstone. Sulcolithos differs from other surface groove‐like burrows or trails in its straight to arched course and its simplicity, for example, absence of curves or meanders, levees, and ornamentation (Knaust, 2019).…”

“…Such sediments are characteristically exposed at the seafloor after erosion of the overlying deposits to deeper levels (Gerard & Bromley, 2008). Balanoglossites is common in the Palaeozoic firmground and hardgrounds that are formed on omission surfaces (Knaust, 2008(Knaust, , 2019Knaust & Dronov, 2013). Some of the firmgrounds in the Zhangxia Formation were produced by storm erosion.…”

Thrombolites and ichnofossils in the Middle Cambrian of south North China Block: Implications for the environmental controls on the evolution of microbes and metazoans

et al. 2021

Handling Editor: M. Luo Thrombolites and ichnofossils are well-preserved in a carbonate succession of the Cambrian (Miaolingian Series) Zhangxia Formation, south North China Block. This provides a chance to investigate the factors controlling the distributions of thrombolites and metazoans. Three types of thrombolites are identified, on the basis of clot shape and their array styles, namely, bushy, columnar, and blocky thrombolites. Bushy thrombolites occur in the lower part of the study unit, columnar thrombolites in the middle, and blocky thrombolites in the upper. Thrombolitic intervals alternate with bioturbated limestones, with the latter including two ichnogenera:
