Bjuvia (Bjuvia simplex) was an extinct organism known from About 247–237 million years ago, with a range in Seasonal valleys and lakeshores · Europe.
Life and ecology
Bjuvia grew in open recovery woodlands and endured seasonal conditions with thick leaves and protected buds.
02 / DISAPPEARANCE
Why did Bjuvia disappear?
Late Triassic floral turnover is possible context; the fossil record does not establish why this large-leaved form disappeared.

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.
