Ostariophysi
Ostariophysi is the second-largest superorder of fish. Members of this superorder are called ostariophysians. This diverse group contains 10,758 species, about 28% of known fish species in the world and 68% of freshwater species, and are present on all continents except Antarctica. They have a number of common characteristics such as an alarm substance and a Weberian apparatus. Members of this group include fish important to people for food, sport, the aquarium industry, and research.

Time the record covers
At least 145 million years on record.
The record covers at least 145.06 Mya to 11.7 ka. No occurrence read is dated outside 149.2 Mya to 0 Mya.
1,588 occurrences of Ostariophysi on record, most of them in the Miocene. 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
1,588 occurrences- Late Jurassicunder 1%
- Early Cretaceous2%
- Late Cretaceous6%
- Paleocene2%
- Eocene12%
- Oligocene7%
- Miocene31%
- Pliocene16%
- Pleistocene21%
- Holocene3%
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 named rock units Ostariophysi has been recovered from, largest first. Drawn where the rock is now, not where it formed. 244 further formations hold fewer occurrences each and are not listed. 422 occurrences have no formation on record, which is common for older literature.

The Paleobiology Database records 846 sites for Ostariophysi, 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 1,588 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. 472 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.
