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

Nunoura et al. 2011
Order:
Caldarchaeales
Family:
Caldarchaeaceae
Genera
  • "Ca. Caldiarchaeum"
  • "Ca. Calditenuis"

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] 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.[1]
