This boundary joint to the LAB define a low-velocity zone in the Australian mantle, which is also present for a similar depth range in the continents (South America, Antarctica and Africa) that were part of the same super-continent Gondwanaland
The ostrich's closest living relatives, the rheas, emu, cassowaries, kiwis, and tinamous, are found in the New World or islands of the southern hemisphere--and it's likely that they, too, rafted away on their own pieces of the former Gondwanaland
It is known that the Antarctic continental shelf is holding rich natural resources (surveys have proven that it has been part of the super-continent Gondwanaland
that back in the Palaeozoic era consisted of South America, Africa and Australia).
WHEN YOU STAND QUIETLY in central Tanzania, the idea of Gondwanaland
makes a lot of sense: you might easily be in parts of remote Australia.
This species-group occurs in the central Drakensberg mountain region, extending through the northern part of Lesotho, its surrounding area stretching to KwaZulu-Natal and neighbouring parts of the Free State, within Gondwanaland
My geologist friends tell me that something over 200 million years ago many of what today are the earth's major continents were joined in a single "supercontinent" known as Gondwanaland
Suffice it to say that this exotic piece of geology, a remnant of Gondwanaland
left behind after the breakup of Pangea, is the 'home' of the GEO CENTRE and is given special attention.
The region was subjected to major rifting episodes during the Mesozoic with the break-up of Gondwanaland
and subsequent formation of the Perth Basin to the west and the Eucla Basin to the south.
In short, build a theme park and there goes Gondwanaland
The islands broke away from Gondwanaland
more than 80 million years ago, and for about 79,999,200 years after that, save for two species of bat, there were no mammals.
Several poems make mention of Livingstone (46) and there is even reference to the geological history of Gondwanaland
When the continents of the Southern Hemisphere that were once all part of the same Gondwanaland
mass broke apart, each took with it genetic material related to plants on lands that drifted in other directions.
