Protepicyon raki
Protepicyon is an extinct monospecific genus of the Borophaginae subfamily of canids native to North America. It lived during the Barstovian stage of the Middle Miocene 16.0—13.6 mya. One of the top predators of its time, it was the probable ancestor of the better known Epicyon, and is known from remains in California and New Mexico.

Time the record covers
At most 3.8 million years on record.
Every occurrence read is dated to somewhere between 16.3 Mya and 12.5 Mya, and nothing in the dating separates them, so that window is what the record shows rather than a span.
5 occurrences of Protepicyon raki on record, most of them in the Miocene. 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
5 occurrences- Miocene100%
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 5 sites for Protepicyon raki, and this reads all of them. The number is how many of those sites it was catalogued from too.
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 5 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. Each entry links to the Paleobiology Database's own record for the work.
