01 / ANSWER FIRST
What was Cladophlebis?
This archive records Cladophlebis under the scientific name Cladophlebis denticulata, with an age of About 201–145 million years ago and a range of Humid woodlands across Laurasia and Gondwana. Finely pinnate fronds carpeted Jurassic understories, each toothed leaflet crossed by repeatedly branching veins.
Cladophlebis is a fossil-fern form genus defined mainly by foliage. Clumps of fronds likely rose from short rhizomes along rivers, lakes and shaded forest floors.

03 / ANATOMY
How was Cladophlebis built?
Overall body plan
Finely pinnate fronds carpeted Jurassic understories, each toothed leaflet crossed by repeatedly branching veins.
Growth architecture
The available record is interpreted through preserved proportions, attachment surfaces, wear and comparison with related organisms. For Cladophlebis, those observations must be separated from features added only for visual reconstruction.
Reproductive structures
Cladophlebis is a fossil-fern form genus defined mainly by foliage. Clumps of fronds likely rose from short rhizomes along rivers, lakes and shaded forest floors.
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 Cladophlebis.
04 / DIET & BEHAVIOUR
How did Cladophlebis live?
Cladophlebis is a fossil-fern form genus defined mainly by foliage. Clumps of fronds likely rose from short rhizomes along rivers, lakes and shaded forest floors. 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 Cladophlebis live?
This archive currently lists About 201–145 million years ago; Humid woodlands across Laurasia and Gondwana. 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
Humid woodlands across Laurasia and Gondwana. This boundary can change when specimens are reidentified or new localities are published.
Time window
About 201–145 million years ago, with the final recorded stage listed as End of the Jurassic. 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 Forest. These labels help explore related records; a habitat reconstruction requires evidence from individual localities.
07 / FOSSIL EVIDENCE
What evidence supports reconstructions of Cladophlebis?
Primary record
Widespread compressions preserve rachises, teeth and forked veins; rare fertile fronds confirm a fern affinity.
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 Cladophlebis within About 201–145 million years ago and Humid woodlands across Laurasia and Gondwana. 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 Cladophlebis disappear?
Fern lineages and forest environments changed into the Cretaceous, and this particular leaf form vanished from younger strata.
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.
