Kombuisia

Kombuisia is a genus of dicynodont from Early to Middle Triassic (Induan to Anisian) of South Africa and Antarctica.

This indicated that this genus existed in a wider biographical region in the southern hemisphere of Pangaea[2] and believed by some to indicate the migration to Antarctica to avoid the rise in global temperatures that led to the mass extinction.

[3] Migration to avoid global warming has been highly controversial because many of the fossils that are found in this region are juvenile and of small body size.

The specimens were originally catalogued in the American Museum of Natural History as Kingoria, however, with no formal reasoning for this categorization, this has since been revised with more up-to-date knowledge of features and speciation.

In a re-evaluation of the cranial anatomy of K. frerensis using the rule of parsimony the most recent conclusion is that Kingoria and Kombuisia are sister taxa of the Kingoriidae clade.

The specimens from South Africa were catalogued in the National Museum of Natural History and were later moved to the Bernard Price Institute for Paleontological Research in Johannesburg.

[2] The lack of a complete skeleton makes it difficult to re-create what the species may have looked like; however, analysis of the skull allows for an estimate of the animal's body size.

[2] Since Fröbisch reviewed the cranial anatomy of K. frerensis and was able to closely relate the genus to Kingoria, subsequent attempts to re-create the species represent similar body plans.

However, further analysis of the body size of many of the specimens found in the lower member of the Fremouw Formation indicated that these species already existed in Antartica.

Kombuisia provides knowledge of specimens in both South Africa and Antarctica; in addition, examination of the cranial length and features indicates a small body size for Kombuisia—too small to migrate seasonally from the Cynognathus Assemblage Zone in South Africa to the central Transantarctic Mountains, which provides further argument against the proposed hypothesis.

These burrows indicate that the environment may have been too harsh for a tetrapod to live above ground and suggest a permanent subterranean residence of many of the species in Antarctica.
