Time the record covers
At least 633 thousand years on record.
The record covers at least 5.333 Mya to 4.7 Mya. No occurrence read is dated outside 11.63 Mya to 1.4 Mya.
42 occurrences of Dinohippus mexicanus on record. 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
42 occurrences- Miocene85%
- Pliocene15%
- Pleistoceneunder 1%
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 named rock units Dinohippus mexicanus has been recovered from, largest first. Drawn where the rock is now, not where it formed. 25 occurrences have no formation on record, which is common for older literature.

The Paleobiology Database records 40 sites for Dinohippus mexicanus, 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 42 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. 7 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. Relayed as the Paleobiology Database holds them, not checked against what they resolve to.

Smithsonian Open Access and MorphoSource were not reached for this taxon, so this list is what the others held rather than everything there is.
This is what the site found, which is not the same as what exists.
