Aulopiformes
Aulopiformes is a diverse order of marine ray-finned fish consisting of some 15 extant and several prehistoric families with about 45 genera and over 230 species. The common names grinners, lizardfishes and allies, or aulopiforms are sometimes used for this group. They are included in the superorder Cyclosquamata, though modern taxonomists consider this superorder to be unwarranted.

Time the record covers
At least 161 million years on record.
The record covers at least 161.5 Mya to 129 ka. No occurrence read is dated outside 165.3 Mya to 0 Mya.
748 occurrences of Aulopiformes on record, most of them in the Late Cretaceous. 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.

748 occurrences- Middle Jurassicunder 1%
- Early Cretaceous2%

- Pliocene1%
- Pleistocene1%
- Holoceneunder 1%
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 479 sites for Aulopiformes, and this reads 240 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.

Each of the 748 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. 282 further references are not listed. 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.
