Eurybacteria is a taxon created by Cavalier-Smith, [1] which includes several groups of Gram-negative bacteria. In this model, it is the ancestor of gram positive bacteria. [2] Their endospores are characterized by producing and presenting external flagella or mobility by bacterial displacement.
Specifically, it includes:
In the standard classification, Selenobacteria are usually included in the phylum Bacillota, whereas fusobacteria and togobacteria are classified as their own groups.
The following graph shows Cavalier-Smith's version of the tree of life, indicating the status of eurybacteria. Cavalier-Smith's Tree of Life, 2006 [cstol 1]
