Aigarchaeota
Scientific classification
Domain:
Kingdom:
Superphylum:
Phylum:
"Aigarchaeota"

Nunoura et al. 2011
Order:
"Caldarchaeales"

Rinke et al. 2020[1]
Families
  • "Caldarchaeaceae"
  • "Wolframiiraptoraceae"

The "Aigarchaeota" are a proposed archaeal phylum of which the main representative is Caldiarchaeum subterraneum.[2] It is not yet clear if this represents a new phylum or a Nitrososphaerota order, since the genome of Caldiarchaeum subterraneum encodes several Nitrososphaerota-like features.[3] The name "Aigarchaeota" comes from the Greek αυγή, avgí, meaning "dawn" or "aurora", for the intermediate features of hyperthermophilic and mesophilic life during the evolution of its lineage.[2]
