Xerus
Xerini is a tribe of ground squirrels occurring in Africa and Asia. With the tribes Marmotini and Protoxerini, they form the subfamily Xerinae. There are five living genera—Xerus, the unstriped ground squirrel; Euxerus, the striped ground squirrel; Geosciurus, the Cape and mountain ground squirrels; Atlantoxerus, containing the living Barbary ground squirrel of North Africa and some extinct species; and Spermophilopsis, containing the long-clawed ground squirrel of Central Asia.

Time the record covers
At least 15 million years on record.
The record covers at least 15.98 Mya to 11.7 ka. No occurrence read is dated outside 16.9 Mya to 0 Mya.
16 occurrences of Xerus on record, most of them in the Pliocene. 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
16 occurrences- Miocene17%
- Pliocene39%
- Pleistocene38%
- Holocene6%
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 15 sites for Xerus, 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 16 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.
