Comment:
Metalloporphyrins, and metal-specific porphyrins (e.g. VO-porphyrins), are summed concentrations of multiple compounds shown in Fig. S2 (Connock et al., 2022). Metal abundances are from previous work (Owens et al., 2006; doi:10.1016/j.epsl.2016.05.046). Horizontal black lines bracket the OAE 2 interval.
