Aigarchaeota

Aigarchaeota
Scientific classification
Domain:	Archaea
Kingdom:	"Proteoarchaeota" or incertae sedis
Phylum:	"Aigarchaeota" or "Thaumarchaeota"
species
Ca. "Caldiarchaeum subterraneum"

The Aigarchaeota are a proposed archaeal phylum of which the main representative is Caldiarchaeum subterraneum.^[1] It is not yet clear if this represents a new phylum or a thaumarchaeal order, since the genome of Caldiarchaeum subterraneum encodes several thaumarchaeal features.^[2]
