Figure 2

Plant propagules from the botanical record of the Jehol Biota that show a resemblance to some enantiornithine “follicles”. (A) Aggregation of Carpolithes multiseminalis propagules (NIGPAS PB19001). (B) Detail of NIGPAS PB19001 showing propagules with a reticulate surface structure. (C) “Follicles” in the enantiornithine fossil STM 29–8 (from Ref. 1: Fig. S5; used with permission). (D, E) Details of a “follicle” and C. multiseminalis propagules from the framed areas in (B) and (C), respectively (note the different size of the shown structures). Abbreviation: sca, scale or bract. Scale bars equal 10 mm in (A) and (C) and 1 mm in (B, D, E).
