What is fossilized plant that has been found on several continents?

Fossilized plants, such as the ancient tree species known as Glossopteris, have been found on several continents, including South America, Africa, Antarctica, India, and Australia. This plant is significant for providing evidence of the theory of continental drift, as its widespread distribution suggests that these landmasses were once connected in the supercontinent Gondwana. Fossils of Glossopteris indicate that it thrived in a warm, temperate climate before the continents drifted apart.
