Rhynchostruthus socotranus

The Socotra golden-winged grosbeak or Socotra grosbeak is a finch endemic to Socotra, an island in the Indian Ocean off the coast of Yemen. R. socotranus is by some authorities held to be the only species of the then-monotypic genus Rhynchostruthus, including all other golden-winged grosbeaks therein as subspecies. But in recent times the three populations are usually considered a distinct species, with R. socotranus being limited to the Socotra population, the Arabian golden-winged grosbeak becoming R. percivali, and the Somali golden-winged grosbeak R. louisae.

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.

Pleistocene — about 0 of 2 occurrencesHolocene — about 2 of 2 occurrences17 ka–0 Mya — about 2 occurrences512 ka0 Mya

2 occurrences of Rhynchostruthus socotranus 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

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.

30 taxa

The Paleobiology Database records 2 sites for Rhynchostruthus socotranus, 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.

Entered from

1 reference

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.
