Comparison of the frondose features in the Dongpo Formation with uninterrupted chevron marks (A−D) and the Ediacaran Charnia for comparison (E). (A) Uninterrupted chevron marks from the Carboniferous Gull Island Formation, Ireland (modified from Doyle and Hoey, 2022); (B) and (D) frondose forms from the Dongpo Formation (modified from Wang et al., 2026); (C) uninterrupted chevron marks from the Lower Silurian Aberystwyth Grits, Wales (modified from Dżułyński and Walton, 1965); (E) Charnia ewinoni from the Ediacaran of Newfoundland (modified from Pasinetti et al., 2025). All scale bars are 1 cm. Portions of the branch-like structures highlighted in (B-D), primary branches in (E) are offset not opposite and have second (red) and third order branches (green) highlighted as is typical of Ediacaran rangeomorphs.
Earlier this year there was an article on the beautiful new #Ediacaran #Dongpo Biota in China, it has some lovely fossils in it. Well worth a look!
There were also some things interpreted as fronds that we consider to be abiogenic uninterrupted Chevron marks. doi.org/10.1016/j.pr...
