Hipparionini
Hipparionini is an extinct tribe of three-toed equids in the subfamily Equinae. They had body forms similar to modern equines, with high-crowned teeth. They first appeared in North America during the Early Miocene around 17 million years ago, before migrating into the Old World around 11.4–11.0 million years ago. The youngest species date to the end of the early Early Pleistocene, becoming extinct following the arrival of modern equines of the genus Equus to the Old World.

Time the record covers
At least 15 million years on record.
The record covers at least 16.3 Mya to 774 ka. No occurrence read is dated outside 23.04 Mya to 11.7 ka.
1,698 occurrences of Hipparionini 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
1,698 occurrences- Miocene67%
- Pliocene19%
- Pleistocene14%
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 1,230 sites for Hipparionini, and this reads 240 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 1,698 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. 446 further references are not listed. Entries link to doi.org where the Paleobiology Database holds an identifier, and to its own record where it does not.
