Urocyon littoralis
The island fox is a small fox species that is endemic to six of the eight Channel Islands of California. They evolved from their larger mainland gray fox ancestor and have diversified into six subspecies, each confined to its own island and all exhibiting insular dwarfism. Island foxes are generally docile, show little fear of humans, and are easily tamed. Island foxes have played an important role in the spiritual lives of native Channel Islanders. They were likely semi-domesticated as pets, for their pelts, or other functions, like pest control. Genetic and archaeological evidence suggests that the foxes arrived on the islands around 7,000 years ago, probably with the assistance of early human populations.

Time the record covers
At most 210 thousand years on record.
Every occurrence read is dated to somewhere between 210 ka and 0 Mya, and nothing in the dating separates them, so that window is what the record shows rather than a span.
3 occurrences of Urocyon littoralis on record, most of them in the Holocene. 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
3 occurrences- Pleistocene31%
- Holocene69%
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 3 sites for Urocyon littoralis, 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.
