Definition
Meaning
A biogeographic realm comprising the Australian region, New Zealand, and associated islands; an area of the Southern Hemisphere with a distinctive ancient fauna.
In historical biogeography, the southern landmass or realm characterized by its unique marsupial and monotreme fauna, distinct from the northern continents. The term is also used conceptually to discuss ancient Gondwanan distributions.
Linguistics
Semantic Notes
A specialist term from historical biogeography and zoogeography. It contrasts with 'Arctogaea' (northern continents) and 'Neogaea' (Neotropics). Often used in discussions of plate tectonics, marsupial evolution, and Gondwana.

Frequently Asked Questions
No, it is an extremely rare, specialised scientific term from biogeography.
Primarily marsupials (like kangaroos, wombats) and monotremes (platypus, echidna), which evolved in isolation there.
Not exactly. Notogaea is a broader biogeographic realm that includes Australia, New Guinea, New Zealand, and some Pacific islands.
Only in advanced academic texts on historical geography, zoogeography, or the evolution of mammals.
