Quercus semecarpifolia
Quercus semecarpifolia is an Asian species of oak. It is native to the Himalayas and nearby mountains, from eastern Afghanistan through Pakistan, northern India, Nepal, Tibet, and Myanmar to northern Thailand, where it is referred to as kharsu. It is classified in subgenus Cerris, section Ilex.

Time the record covers
At least 13 million years on record.
The record covers at least 15.98 Mya to 2.58 Mya. No occurrence read is dated outside 23.04 Mya to 11.7 ka.
5 occurrences of Quercus semecarpifolia on record. The Paleobiology Database records this as a living group. 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- Miocene20%
- Pliocene7%
- Pleistocene73%
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 Quercus semecarpifolia, 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.

Each of the 5 occurrences read was entered from one of these publications, ordered by how many each accounts for. This is not a search for papers mentioning the name. Entries link to doi.org where the Paleobiology Database holds an identifier, and to its own record where it does not. Relayed as the Paleobiology Database holds them, not checked against what they resolve to.
