Time the record covers
At least 274 million years on record.
The record covers at least 458.2 Mya to 184.2 Mya. No occurrence read is dated outside 468 Mya to 161.5 Mya.
12,000+ occurrences of Spiriferida on record. 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
12,000 occurrences read- Ordovicianunder 1%
- Silurian11%
- Devonian46%
- Carboniferous23%
- Permian19%
- Early Triassicunder 1%
- Early Jurassicunder 1%
- Middle Jurassicunder 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. The read hit its cap, so every figure above is a floor and the shares are of the occurrences read. More on what this infers.

The named rock units Spiriferida has been recovered from, largest first. Drawn where the rock is now, not where it formed. The read hit its cap, so each count is a floor. 1,101 further formations hold fewer occurrences each and are not listed. 1,370 occurrences have no formation on record, which is common for older literature.

The Paleobiology Database records at least 1,057 sites for Spiriferida, 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 12,000 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. That read hit its cap, so each count is a floor. 783 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.
