Ticholeptus
Ticholeptus is an extinct genus of oreodont endemic to North America during the Middle Miocene subepoch, existing for approximately 2.4 million years. Fossils have been uncovered throughout the United States from Florida to Oregon, as well as California, and numerous sites in Nebraska, Nevada, and Montana.

Time the record covers
At most 18 million years on record.
Every occurrence read is dated to somewhere between 23.1 Mya and 5.333 Mya, and nothing in the dating separates them, so that window is what the record shows rather than a span.
53 occurrences of Ticholeptus 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
53 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 52 sites for Ticholeptus, 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.
