Final answer:
Mauritia separated from the supercontinent Gondwana 61 to 83.5 million years ago during the breakup of Gondwana, which was part of the Earth's geological history of continental drift.
Step-by-step explanation:
Mauritia separated from Gondwana 61 to 83.5 million years ago. Gondwana was a supercontinent that existed during the Neoproterozoic and began to break up during the Jurassic period, ultimately concluding its separation in the Eocene epoch. The breaking away of landmasses such as Mauritia from Gondwana was part of the complex process of continental drift, which has shaped the current geographic configuration of our planet over hundreds of millions of years. Mauritius is a piece of continental crust that broke off the supercontinent as it fragmented. Madagascar is an example of another landmass that separated from the mainland of Africa, developing its unique environmental conditions and biodiversity after splitting from Gondwana over 160 million years ago.
