Pachycynodon
Pachycynodon is an extinct genus of arctoid belonging to the family Amphicynodontidae. It lived in Europe during the late Oligocene epoch. They were relatively small carnivores. They have deep mandibles that are robust, even more robust than that of genus Amphicynodon. Their muzzle is elongated.

Time the record covers
At least 4.2 million years on record.
The record covers at least 27.3 Mya to 23.04 Mya. No occurrence read is dated outside 33.9 Mya to 20.45 Mya.
13 occurrences of Pachycynodon on record, most of them in the Oligocene. 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
13 occurrencesThese 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 7 sites for Pachycynodon, 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 13 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. Entries link to doi.org where the Paleobiology Database holds an identifier, and to its own record where it does not.
