01 / DEFINITION & ECOLOGY
What was Dicranophyllum?
Dicranophyllum (Dicranophyllum gallicum) was an extinct organism known from About 299–272 million years ago, with a range in Seasonal river-valley woodland · France.
Life and ecology
It grew as a shrub or small tree in seasonally dry valleys and survived unfavorable periods as seeds.
02 / DISAPPEARANCE
Why did Dicranophyllum disappear?
Permian drying and seed-plant turnover are possible context; the fossil record does not establish why the species disappeared.
03 / EVIDENCE
How do scientists know about Dicranophyllum?
Cuticle-bearing shoots and fertile organs establish the lineage; whole-plant form remains reconstructed.

Use the scientific name to compare taxonomy, occurrence records and the fossil record. Database coverage and classifications may differ.
05 / REVISION HISTORY
How has this record changed?
- Rewrote an extinction cause that presented environmental or faunal turnover as established; it is now given as context the record does not prove.
- Verified authoritative entity sources and added three responsive reconstruction sizes.
- Initial bilingual species record published.
