Hemicyon
Hemicyon, also known as the "dog-bear", is an extinct genus of hemicyonine bear, which probably originated in Eurasia but was found in Europe, Asia and North America during the Miocene epoch, existing for approximately 16 to 13 mya. Hemicyon is the best-known genus in the Hemicyoninae, a subfamily intermediate between bears and their Caniform ancestors, but most often classified as bears. Hemicyonine bears should not be confused with Amphicyonids (bear-dogs), which are their own separate family of carnivores.

Time the record covers
At least 4.4 million years on record.
The record covers at least 16.9 Mya to 12.5 Mya. No occurrence read is dated outside 23.04 Mya to 5.333 Mya.
27 occurrences of Hemicyon 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
27 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 20 sites for Hemicyon, 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 27 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. 6 further references are not listed.
