Entelodon
Entelodon, formerly called Elotherium, is an extinct genus of entelodont artiodactyl found in Eurasia. Fossils of species of Entelodon are found in Paleogene strata ranging in age from the Houldjinian until the Rupelian epoch of the early Oligocene.

Time the record covers
At least 3.8 million years on record.
The record covers at least 37.71 Mya to 33.9 Mya. No occurrence read is dated outside 48.07 Mya to 27.3 Mya.
22 occurrences of Entelodon on record, most of them in the Eocene. 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
22 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.
