Megalohyrax
Megalohyrax is an extinct hyrax-grouped genus of herbivorous mammal that lived during the Oligocene, about 33-30 million years ago. Its fossils have been found in Africa and in Asia Minor.

Time the record covers
At least 25 million years on record.
The record covers at least 41.03 Mya to 15.98 Mya. No occurrence read is dated outside 56 Mya to 13.82 Mya.
10 occurrences of Megalohyrax 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
10 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 8 sites for Megalohyrax, 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 10 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.
