Time the record covers
At least 65 million years on record.
The record covers at least 66 Mya to 11.7 ka. No occurrence read is dated outside 100.5 Mya to 0 Mya.
228 occurrences of Sphyrna 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
228 occurrences- Late Cretaceousunder 1%
- Paleoceneunder 1%
- Eocene7%
- Oligocene5%
- Miocene71%
- Pliocene9%
- Pleistocene4%
- 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 159 sites for Sphyrna, and this reads all of them. Of that, one read hit the database's own return limit, so every count below is a floor rather than a total. 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 228 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. 105 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.
