Trachinus
Trachinus is a genus of ray-finned fish in the weever family Trachinidae consisting of eight extant species and a few extinct species. All species of the genus inhabit the waters of the eastern Atlantic Ocean with the exception of T. cornutus, which inhabits the southeastern part of the Pacific Ocean. Three of the seven Atlantic species occur near the coasts of Europe.

Time the record covers
At least 45 million years on record.
The record covers at least 48.07 Mya to 2.58 Mya. No occurrence read is dated outside 56 Mya to 1.8 Mya.
51 occurrences of Trachinus 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
51 occurrences- Eocene25%
- Oligocene22%
- Miocene48%
- Pliocene2%
- Pleistocene2%
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 42 sites for Trachinus, 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.

Each of the 51 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. 9 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.
