Alectryon
Alectryon is a genus of about 30 species of trees and shrubs from the family Sapindaceae. They grow naturally across Australasia, Papuasia, Melanesia, western Polynesia, east Malesia and Southeast Asia, including across mainland Australia, especially diverse in eastern Queensland and New South Wales, the Torres Strait Islands, New Guinea, the Solomon Islands, New Caledonia, New Zealand, Vanuatu, Fiji, Samoa, Hawaii, Indonesia and the Philippines. They grow in a wide variety of natural habitats, from rainforests, gallery forests and coastal forests to arid savannas and heaths.

Time the record covers
At least 15 million years on record.
The record covers at least 15.98 Mya to 774 ka. No occurrence read is dated outside 27.3 Mya to 0 Mya.
19 occurrences of Alectryon on record, most of them in the Pleistocene. 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
19 occurrences- Oligocene2%
- Miocene3%
- Pleistocene95%
- Holoceneunder 1%
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 19 sites for Alectryon, 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.
