description Glossopteris indica Overview
Glossopteris indica is a fossil species assigned to Glossopteris, a widespread genus of seed plants that flourished across Gondwana during the Permian Period. Its characteristic tongue-shaped leaves occur in rocks from India and other parts of the former southern supercontinent. The broad geographic distribution of Glossopteris fossils helped support the reconstruction of Gondwana and became important evidence in the historical development of continental-drift theory.
help Glossopteris indica FAQ
What did Glossopteris indica look like?
It is known especially from broad, tongue-shaped leaves with a strong central midrib and a network of branching veins. Those leaves belonged to extinct woody seed plants rather than to a modern fern.
Why was Glossopteris evidence for continental drift?
Glossopteris fossils occur across India, South Africa, Australia, Antarctica, and South America. That distribution is difficult to explain across modern oceans but makes sense when those lands are reconstructed as parts of Gondwana.
When did Glossopteris indica live?
Glossopteris plants flourished across Gondwana during the Permian Period. Their communities largely disappeared during the end-Permian mass extinction about 252 million years ago.
Is Glossopteris indica a fern?
No, despite the fern-like appearance of some leaf fossils, Glossopteris was a seed plant. Fossil reproductive structures associated with its leaves distinguish it from true ferns, which reproduce through spores.
