Palaeoniscidae
Palaeoniscidae is an extinct family of "palaeoniscoid" ray-finned fishes (Actinopterygii). The family includes the genus Palaeoniscum and potentially other Palaeozoic and Mesozoic early actinopterygian genera. The name is derived from the Ancient Greek words παλαιός and ὀνίσκος.

Time the record covers
At least 239 million years on record.
The record covers at least 382.31 Mya to 143.1 Mya. No occurrence read is dated outside 383.4 Mya to 121.4 Mya.
369 occurrences of Palaeoniscidae on record, most of them in the Late Triassic. 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
369 occurrences- Devonian3%
- Carboniferous22%
- Permian31%
- Early Triassic2%
- Middle Triassic8%
- Late Triassic32%
- Early Jurassic2%
- Late Jurassicunder 1%
- Early Cretaceousunder 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 277 sites for Palaeoniscidae, 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.
