Sciurini
Sciurini is a tribe that includes about forty species of squirrels, mostly from the Americas. It includes five living genera—the American dwarf squirrels, Microsciurus; the Bornean Rheithrosciurus; the widespread American and Eurasian tree squirrels of the genus Sciurus, which includes some of the best known squirrel species; the Central American Syntheosciurus; and the American pine squirrels, Tamiasciurus. Like other arboreal squirrels, they are sometimes referred to as tree squirrels.

Time the record covers
At least 37 million years on record.
The record covers at least 37.71 Mya to 11.7 ka. No occurrence read is dated outside 41.03 Mya to 0 Mya.
184 occurrences of Sciurini 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
184 occurrencesThese 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 named rock units Sciurini has been recovered from, largest first. Drawn where the rock is now, not where it formed. One further formation holds fewer occurrences and is not listed. 130 occurrences have no formation on record, which is common for older literature.

The Paleobiology Database records 164 sites for Sciurini, 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 184 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. 89 further references are not listed. 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.
