Cycadophyte
Cycas circinalis.
Fossil cycads have been discovered in numerous regions where the plants are no longer found today, providing evidence that these areas once experienced much milder climates than they do now. These locations include:
- Greenland
- Antarctica
- Alaska
- France
- Austria
- Argentina1
The presence of these fossils in currently temperate and subarctic regions indicates that the global climate was significantly warmer during the Mesozoic Era, when cycads and cycadeoids were widespread.12
