Petroica australis

The South Island robin is a sparrow-sized bird found only in New Zealand, where it has the status of a protected endemic species. The birds are sparsely distributed through the South Island and Stewart Island / Rakiura, although the distribution is not continuous. The nominate, and the Stewart Island robin are the two subspecies. The species is closely related to the North Island robin, and also to the extremely rare black robin of the Chatham Islands.

Time the record covers

At most 129 thousand years on record.

Every occurrence read is dated to somewhere between 129 ka and 0 Mya, and nothing in the dating separates them, so that window is what the record shows rather than a span.

17 occurrences of Petroica australis 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

17 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.

The Paleobiology Database records 17 sites for Petroica australis, 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

4 references

Each of the 17 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. Relayed as the Paleobiology Database holds them, not checked against what they resolve to.
