Subulitidae
Subulitidae is an extinct taxonomic family of fossil sea snails, marine gastropod molluscs in the clade Caenogastropoda.

Not Subulitidae. This is Subulites Emmons, 1842, a relative — both are Subulitidae.

Time the record covers
At least 223 million years on record.
The record covers at least 483.4 Mya to 259.857 Mya. No occurrence read is dated outside 486.85 Mya to 254.14 Mya.
490 occurrences of Subulitidae on record, most of them in the Ordovician. 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
490 occurrences- Ordovician87%
- Silurian6%
- Devonian5%
- Carboniferousunder 1%
- Permian2%
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 253 sites for Subulitidae, and this reads 240 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 490 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. 75 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.
