01 / ANSWER FIRST
What was Glossopteris?
This archive records Glossopteris under the scientific name Glossopteris browniana, with an age of About 299–252 million years ago and a range of Gondwana · Antarctica, Australia, India and southern Africa. Tongue-shaped leaves across the southern continents became important evidence that Gondwana was once united.
Glossopteris was a woody seed plant that formed high-latitude forests under severe seasonal light. Deciduous leaves and underground structures helped it endure cold dark seasons.

03 / ANATOMY
How was Glossopteris built?
Overall body plan
Tongue-shaped leaves across the southern continents became important evidence that Gondwana was once united.
Growth architecture
The available record is interpreted through preserved proportions, attachment surfaces, wear and comparison with related organisms. For Glossopteris, those observations must be separated from features added only for visual reconstruction.
Reproductive structures
Glossopteris was a woody seed plant that formed high-latitude forests under severe seasonal light. Deciduous leaves and underground structures helped it endure cold dark seasons.
Growth and individual variation
A single specimen does not define the whole species. Size, maturity, preservation and possible sex differences are considered before anatomical traits are treated as typical of Glossopteris.
04 / DIET & BEHAVIOUR
How did Glossopteris live?
Glossopteris was a woody seed plant that formed high-latitude forests under severe seasonal light. Deciduous leaves and underground structures helped it endure cold dark seasons. This ecological reconstruction is strongest where anatomy, associated organisms and the depositional setting point in the same direction.
05 / DIET & BEHAVIOUR
What shaped its ecological limits?
Its populations depended on plant communities, soils, water availability and climate. Changes in any one factor did not necessarily cause immediate extinction, but interacting pressures could reduce range, recruitment and resilience.
06 / RANGE & HABITAT
Where and when did Glossopteris live?
This archive currently lists About 299–252 million years ago; Gondwana · Antarctica, Australia, India and southern Africa. Fossil or historical occurrence data describe where evidence has been found, not every place the taxon once occupied. Species-level age and range limits still require source-specific review.
Documented geographic range
Gondwana · Antarctica, Australia, India and southern Africa. This boundary can change when specimens are reidentified or new localities are published.
Time window
About 299–252 million years ago, with the final recorded stage listed as End-Permian. Rock units and dating uncertainty mean the true biological range may extend beyond the known record.
Environmental setting
The archive uses the broad habitat labels Polar. These labels help explore related records; a habitat reconstruction requires evidence from individual localities.
07 / FOSSIL EVIDENCE
What evidence supports reconstructions of Glossopteris?
Primary record
Matching leaves, wood, roots and reproductive organs across continents reconstruct the plant and support continental drift.
Comparative anatomy
Preserved structures are compared with close and functionally similar organisms. The method can constrain posture and function, but analogy alone cannot prove colour, behaviour or soft tissue.
Age and locality
Stratigraphy and occurrence records place Glossopteris within About 299–252 million years ago and Gondwana · Antarctica, Australia, India and southern Africa. Reworked fossils and uncertain provenance are treated cautiously.
Open entity records
Links below connect the archive to available taxonomic and occurrence records. A matching name does not verify every ecological claim, and related-taxon links provide comparison rather than an exact species match.
08 / DISAPPEARANCE & DEBATE
Why did Glossopteris disappear?
End-Permian warming, drought, fire and ecosystem collapse erased glossopterid forests.
The last fossil or observation marks the youngest evidence currently known, not necessarily the death of the final individual. Explanations are strongest when timing, environmental change and population biology agree; otherwise the profile preserves uncertainty instead of assigning a single dramatic cause.
