Ctenodactylidae
Gundis or comb rats are a group of small, stocky, African rodents in the family Ctenodactylidae. They live in rocky deserts across Northern Africa. The family comprises four living genera and five species, as well as numerous extinct genera and species. They are in the superfamily Ctenodactyloidea. Local people in northern Africa have always known about gundis, however they first came to the notice of Western naturalists in Tripoli in 1774, and were given the name gundi mice. While they are not regarded as pests, some people hunt gundis for food.

Time the record covers
At least 35 million years on record.
The record covers at least 37.71 Mya to 1.8 Mya. No occurrence read is dated outside 56 Mya to 774 ka.
262 occurrences of Ctenodactylidae on record, most of them in the Oligocene. 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
262 occurrences- Eocene2%
- Oligocene72%
- Miocene25%
- Plioceneunder 1%
- Pleistoceneunder 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 146 sites for Ctenodactylidae, 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.
