Glossopteris

Glossopteris is the largest seed fern that ever existed. It lived in the Permian period. it was also a really dumb tree

Description
Glossopteris was a woody tree, and some examples grew to over 30 meters in height. They had large, broad leaves which are commonly preserved as fossils. Their exact appearance in full is uncertain, because complete trees have not been found.

Distribution
Glossopteris fossils are found on nearly all continents in the Southern Hemisphere. This distribution led many to present it as evidence for continental drift, as it was likely that the tree originated on one landmass that later split into many different ones. This proposed supercontinent was called Gondwana, and existed as part of Pangaea.

History
Glossopteris was first described in 1828 as a type of fern.
