## The Rainforest Beneath Antarctica

Status: Coming soon
Last prepared: 11 August 2026

Researchers studying sediment cores from West Antarctica found preserved forest soil, roots, pollen and spores dating to the mid-Cretaceous, around 90 million years ago.

This film reconstructs the evidence carefully. It follows the core from the seabed into the laboratory, then asks what polar darkness, atmospheric carbon dioxide and global temperatures must have been like for that ecosystem to exist.

## Evidence, inference and imagination

### Evidence: A temperate rainforest existed near the South Pole

The core contained in-situ roots, pollen and spores consistent with a swampy temperate rainforest environment.

Sources: Temperate rainforests near the South Pole during peak Cretaceous warmth

### Evidence: The forest endured polar darkness

Its latitude meant a prolonged winter period without sunlight.

### Inference: Atmospheric conditions must have retained exceptional heat

The discovery constrains estimates of temperature and carbon dioxide during the mid-Cretaceous greenhouse climate.

### Imagination: The camera travels through the ancient forest

The on-screen ecosystem is an AI-created reconstruction informed by the evidence, not recovered footage.
