Extended Data Fig. 4: Ultrastructure and EDS spectra of Ammonia veneta.The alternative text for this image may have been generated using AI.

TEM images of A. venata thin-sections (A&B) and locations and related spectra of EDS point measurements (B1-B3). Note the abundant empty vesicles with 0.5–3 µm diameter and the absence of phosphorus in EDS spectra B1 & B3. Only the vesicle, which still had visible content showed a visible phosphorus peak in the EDS spectrum (B2). The TEM/EDS experiment of 3 different specimens of A. veneta.
