Phenacomys intermedius
The western heather vole is a small vole found in western North America. Until recently, the eastern heather vole was considered to be a subspecies. They have short ears with stiff orange hair inside and a short thin tail which is paler underneath. Their long soft fur is brownish with silver grey underparts. They are roughly 14 cm (5.5 in) long with a tail length shorter than one-half their body length, approximately 50 mm (2.0 in). They weigh about 40 g (1.4 oz).

Time the record covers
At least 645 thousand years on record.
The record covers at least 774 ka to 129 ka. No occurrence read is dated outside 2.58 Mya to 0 Mya.
24 occurrences of Phenacomys intermedius 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
24 occurrences- Pleistocene99%
- Holocene1%
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 24 sites for Phenacomys intermedius, 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 24 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. 8 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.
