Macaca cyclopis
The Formosan rock macaque, also known as the Formosan rock monkey or Taiwanese macaque, is a macaque endemic to the island of Taiwan, which has also been introduced to Japan. Besides humans, Formosan rock macaques are the only native primates living in Taiwan. The species was first described by Robert Swinhoe in 1862.

Time the record covers
At most 763 thousand years on record.
Every occurrence read is dated to somewhere between 774 ka and 11.7 ka, and nothing in the dating separates them, so that window is what the record shows rather than a span.
2 occurrences of Macaca cyclopis on record, most of them in the Pleistocene. The Paleobiology Database records this as a living group. 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
2 occurrences- Pleistocene100%
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 2 sites for Macaca cyclopis, and this reads all of them. The number is how many of those sites it was catalogued from too.
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 2 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. Each entry links to doi.org. Relayed as the Paleobiology Database holds them, not checked against what they resolve to.
