The new version of EO is much better than the old one...Yes, it was a codex, Bacterium Bullaris (lime), the Osseus is called Pumice (green), that's according to Elite Observatory, I open it every time I play now, just too lazy to look at it before.
Though I haven't used it recently as a) I'm in the bubble and b) I'm playing the BGS game lately, for which Vista Genomics transactions do not produce Influence, only Reputation, which I'm already full of and continue to be so.
Out of curiosity, how many codex entries have you added by now? It must be quite a few. Not sure if there's any easily acquired statistics for that though...
