In Jainism, Antarctica is not described as a continent connected to past yugas.

Jain cosmology explains time through utsarpini and avasarpini and describes the world mainly in terms of Jambudvipa, Dhātakīkhanda, Puṣkarārdha, and other cosmological regions—not through modern continents like Antarctica. So, from a Jain scriptural point of view, Antarctica is a modern geographical name, not a yuga-based concept.

If you are asking in a symbolic sense, the only clear Jain connection would be this:

• past yugas refer to vast time cycles,
• while Antarctica belongs to the present physical world’s geography,
• so there is no direct traditional Jain linkage between the two.

In short: Antarctica is not part of classical Jain yuga geography.
