Se trata de un mamifero de tamano considerable, el mas grande de Gondwana y solo algo mas pequeno que un triconodonte de Laurasia hallado por Yaoming Hu y sus colaboradores en 2005 en la China actual, Repenomamus robustus, cuyo hallazgo levanto un revuelo considerable entre los especialistas porque se trataba de un carnivoro capaz de alimentarse de las crias de los dinosaurios.
A breakdown in disparity between Gondwanan and Laurasian marginal marine ecosystems towards the end of the Devonian has previously been noted, possibly caused by increasing proximity of Laurasia to Gondwana (Young 1987).
The researchers believe a barrier free connection would have allowed the beasts' migration from Laurasia and Gondwana - the northernmost parts of Pangea - to the southern tip of the continent.
If you look up Gondwana, you will see in the Late Triassic an area between Gondwana (South America, Africa, India, Antarctica and Australia) and Laurasia (North America, Europe and Asia) called the Tethys Sea.
At the time of divarication, Laurasia, still intact, would have facilitated movement between regions.
During the Triassic, the Earth's continents were united as Pangaea, with one southern landmass known as Gondwana and one northern one known as Laurasia. Africa was part of Gondwana, which is also where most of the Triassic dinosaur fossils have been found.
About 200 million years ago, Pangaea (super continent) broke into two new continents, Laurasia existing as a part of the split, in the late Mesozoic era and Gondwanaland.
The existence of the Tethys Ocean was first postulated and named (after a goddess of rivers rather than seas) by the geologist Eduard Suess in 1893 as a sea between the supercontinents Gondwana and Angaraland (later called Laurasia).The existence of shallow seas in the past has been enormously significant geologically (for example, in identifying oil-bearing strata), yet Tethys, which came into being about 256 million years ago and started closing up only in the past ten million years, is nevertheless one detail albeit an important one--in the larger story of continental drift, itself until recently sidelined by plate tectonics.

Presumably the early angiosperms radiated into Laurasia in the region of what is now North Africa, the Iberian Peninsula, and the Middle East.
As late as 120 million years ago, many of the landmasses that we identify as continents today fit together like two giant puzzle pieces: Gondwana in the southern hemisphere and Laurasia in the northern hemisphere.
The Kazakhstan and North China plates form a part of eastern Laurasia which had accreted by late Devonian times; the part of Myanmar which produces Cretaceous amber (Grimaldi et al.
