Proposed archaeal phylum

Aigarchaeota
Scientific classification
Domain: Archaea
Kingdom: "Proteoarchaeota"
Superphylum: TACK
Phylum: "Aigarchaeota"
Nunoura et al. 2011
Order: "Caldarchaeales"
Rinke et al. 2020
Families
  • "Caldarchaeaceae"
  • "Calditenuaceae"
  • "Wolframiiraptoraceae"

The "Aigarchaeota" are a proposed archaeal phylum of which the main representative is Caldiarchaeum subterraneum. 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. 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.
