Glossopteris, genus of fossilized woody plants known from rocks that have been dated to the Permian and Triassic periods (roughly 300 to 200 million years ago), deposited on the southern supercontinent of Gondwana.

What kind of plant was Glossopteris?
Glossopteris was a woody, seed-bearing shrub or tree, some apparently reaching 30 meters tall. They had a softwood interior that resembles conifers of the family Araucariaceae.
What do you mean by Glossopteris?
1 capitalized : a genus of chiefly Permian and Triassic fossil ferns or fernlike plants characterized by thick entire fronds with anastomosing veins. 2 plural -es : any plant of the genus Glossopteris.
Why are Glossopteris fossils important?
Glossopteris fossils provide important evidence for currently accepted distribution of continental plates in the Permian period that ended 250 million years ago. ... The mass extinction that marks the end of the Permian period is believed to have led to the disappearance of Glossopteris.
What kind of organism was the Glossopteris What did it look like what type of climate did it live in?
Glossopteris is an extinct type of plant referred to as a seed fern. These plants most likely thrived in warm tropical climates.
What is the habitat of Glossopteris?
Glossopteris was a genus of woody gymnosperms that was common through out the continent of Gondwana, providing another piece of evidence for the theory of continental drift (Fossil Museum 2010). They were found in wet, swampy habitats, much like bald cypress (Fossil Museum 2010).
What continents have Glossopteris fossils been found on?
The Glossopteris fossil is found in Australia, Antarctica, India, South Africa, and South America—all the southern continents. Now, the Glossopteris seed is known to be large and bulky and therefore could not have drifted or flown across the oceans to a separate continent.
On which continent were fossils of both Glossopteris and Lystrosaurus?
Fossils of Lystrosaurus are only found in Antarctica, India and South Africa. Glossopteris was a woody, seed-bearing shrub or tree, named after the Greek descripton of 'tongue' – a description of the shape of the leaves.
How many Glossopteris fossils have been found?
Over seventy different Glossopteris species have been identified from fossils scattered throughout South America, Africa, Australia, India, and the Antarctic.
How do Glossopteris fossils support Pangaea?
WEGNER'S EVIDENCE FOR CONTINENTAL DRIFT Evidence from fossilized organisms and mountain chains can be used to reconstruct the positions of today's continents and landmasses to form the supercontinent Pangea. Glossopteris ferns had very heavy seeds that could not move by wind or drift on ocean currents.
Which plant is known as Fossil Plant?
Ginkgo biloba (also called the maidenhair tree) is often referred to as a “living fossil,” because it is the only remaining representative of a perished botanical family (the Ginkgoaceae) and is considered to be the oldest living tree species [1]. The plant is dioecious, that is, there are male and female trees.
What is a plant fossil called?
Plant fossils are classified into two groups: (1) macrofossils, which are the larger plant members, such as stems and leaves, usually detached and often fragmented; and (2) microfossils, which are the shells or resistant outer walls of minute plants, such as diatoms, or of pollen grains and spores. Fruits and seeds ...
Are there trees in Antarctica?
On the other end of the world in the the Antarctic, one can find another type of "tree" - or rather remains of trees. ... These petrified treed formed approximately 40 million years ago, when the Antarctic climate was just starting to cool down, and and the Antarctic Ice Sheet only covered land around the South Pole.
What does the discovery of Glossopteris fossil in five continent suggest?
The glossopteris fossils reflects the evidence of separation of continents like southern Africa, Australia, India and Antarctica which was largely separated by huge and wide ocean which was larlier connected with each other.
Where did the Glossopteris plant grow?
Glossopteris flora The fossil flora that succeeds the Permian glacial deposits of South Africa, Australia, South America, and Antarctica. It grew in a cold, wet climate, while the flora of North America and Europe existed under warm conditions.
Where do fern plants grow?
Ecologically, the ferns are most commonly plants of shaded damp forests of both temperate and tropical zones. Some fern species grow equally well on soil and upon rocks; others are confined strictly to rocky habitats, where they occur in fissures and crevices of cliff faces, boulders, and taluses.
What is paleontological evidence?
Paleontological Evidence
Fossils are the geological remains and scientific traces of organisms in the past excavated from the soil. ... An example of paleontological evidence is the presence of rings on the surface of an oyster which represents the number of years of its life.
