Pedigree: Phylum Euryarchaeota

The PEDIGREE of

Phylum Euryarchaeota

aka Kingdom Euryarchaeota; (recent evidence shows Euryarchaeota to be polyphyletic, with Thermococci and some other classes in a separate phylum)

"Child(ren)": Class Methanobacteria ; Class Methanopyri ; Class Halobacteria ; Methanomicrobia (clades with Halobacteria) ; Archaeoglobi (3 genera :: sulfate-reducing : iron-reducing : benzoate-reducing) ; Methanococci ; Thermococci ; Thermoplasmata
