Gerygone albofrontata · Epoch Explorer

The Chatham Islands gerygone, also known as the Chatham gerygone or Chatham Island warbler, is a species of bird in the family Acanthizidae. It is endemic to the Chatham Islands. The Chatham Islands gerygone is larger than and differs in plumage from the related grey warbler of mainland New Zealand. Both warblers were discovered and named by G. R. Gray in 1845. The grey and Chatham Island warblers are the only two members of the Australasian family Acanthizidae found in New Zealand.

Time the record covers

At most 12 thousand years on record.

The one occurrence read is dated to somewhere between 11.7 ka and 0 Mya, which is a dating window rather than a span.

1 occurrence of Gerygone albofrontata 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

1 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.
