Auchenoceros
The āhuru is a species of morid cod found in waters off the eastern coast of New Zealand and to the south as well as in the Cook Strait. It is found at depths from 5 to 420 m. This species grows to 13 cm (5.1 in) in total length. It is the only known species of its genus.

Time the record covers
At least 23 million years on record.
The record covers at least 25.2 Mya to 1.63 Mya. No occurrence read is dated outside 27.3 Mya to 340 ka.
35 occurrences of Auchenoceros on record, most of them in the Miocene. The Paleobiology Database records this as a living group, and the chart stops with its fossils rather than at the present. 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
35 occurrences- Oligocene3%
- Miocene83%
- Pliocene6%
- Pleistocene9%
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 34 sites for Auchenoceros, 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.
