Camarhynchus pauper
The medium tree finch is a species of Darwin's finch. It is endemic to the Galápagos Islands, where it occurs only on Floreana Island. Its name derives from its intermediate size between the small tree finch and large tree finch. Due to its limited geographic range and its high breeding mortality following the introduction of the parasitic avian vampire fly, the medium tree finch is listed as critically endangered on the IUCN Red List.

Time the record covers
At most 12 thousand years on record.
Every occurrence read is dated to somewhere between 11.7 ka and 0 Mya, and nothing in the dating separates them, so that window is what the record shows rather than a span.
2 occurrences of Camarhynchus pauper on record, most of them in the Holocene. 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- Holocene100%
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 Camarhynchus pauper, 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.
