Amentotaxus
Amentotaxus is a genus of conifers (catkin-yews) comprising five species, treated in the Taxaceae. The genus is native to subtropical Southeast Asia, from Taiwan west across southern China to Assam in the eastern Himalaya, and south to Vietnam. The species are evergreen shrubs and small trees reaching 2–15 m tall.

Time the record covers
At least 16 million years on record.
The record covers at least 72.2 Mya to 56 Mya. No occurrence read is dated outside 89.8 Mya to 33.9 Mya.
5 occurrences of Amentotaxus on record, most of them in the Paleocene. The Paleobiology Database records this as a living group, and the chart stops with its fossils rather than at the present. Bar height is expected occurrences, not a count: each fossil is spread across the span it is dated to, so a tall narrow bar means tight dating and a low wide one means loose.
When
5 occurrences- Late Cretaceous20%
- Paleocene40%
- Eocene40%
These are dates about fossils, not the animal: the record can only begin after it arose and end before it died out, so either end may reach further. Shares are expected occurrences: a fossil dated to a span is counted partly in each period it straddles. More on what this infers.

The Paleobiology Database records 5 sites for Amentotaxus, and this reads all of them. The number is how many of those sites it was catalogued from too. The 24 sharing the most are listed.
This is not a list of everything alive at the time. It is only what has come out of the same ground as this animal and been written down.
